PC doesn't power up after cmos

Q: PC doesn't power up after cmos

First, my computer had BSOD every time i start up my computer so i reset the cmos but after my computer didnt power up at all, no fan, no sound, nothing other then the green light on the mobo when everything is plugged in. I try turning on the computer with another PSU that i had but still nothing. Anyone has any idea what is wrong or what i can do?

Preferred Solution: PC doesn't power up after cmos

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Hi CS,
did you clear the CMOS by removing, and moving a jumper pin?....if you did make sure that the metal insert (the part that connects the pins) in the jumper didn't fall out or come out of the plastic casing and stay on the second set of pins when you reset the CMOS.

I was playing around with my overclocking settings on my recently new asus p5n-d. It has ai tuning which gives me the option to overclock 5%, 10%, 15%, 20%. I decided after playing around with other overclock settings ( got up around 2.66 ghz without heat issues) to go for the 20% and see how it would run. I picked it, saved to bios and restarted. Upon restarting my bios updated itself (flashed?) and then restarted. Upon restart I have no display yet everything appears to be running. If i remove my ram i get the usual ram beeps, no beeps if i remove my video card. I pulled my cmos battery a few times leaving it out for hours to no avail. My monitor also claims to be getting no input. Any help would be greatly appreaciated.

A:Monitor doesn't come on unless I clear CMOS - possibly ram issue

A tour through the ABIT manual, or a discussion with the ABIT tech support people should take you to a fix. I suspect you have a minor setup problem, and if you go back through the checklist when rested and not frustrated, you will come down to a solution. I doubt that it is anything serious.
Press the shutdown button for 12 seconds. When off, remove your CMOS battery for a few minutes. Now look for little, but obvious things.

I have a Dell Dimension 4500
When I power it up with only: The motherboard, Power Supply, Video Card, 1 Stick of RAM, and the Processor I dont get any beeps On the back of the computer the diagnostic codes tell me "Memory modules are detected, but a memory failure has occurred." The thing that bothers me is that their is no video out signal, and i am not getting anything on screen. Is thier any way to findo out what is wrong without buying the ram. PLEASE TELL ME HOW TO RESET THE CMOS. Maby that is the problem. The computer has worked before And I dont know what the problem is. It has to be bios/COMS related because nothing is coming up on screen. please help!!!!!

A:I get power but no boot!!! Cmos?

There should be some CMOS reset jumper on the motherboard. There are many instrucitions to do that. Optionally, you can unplug power cord, hold the power button for about 10 secs, remove your CMOS battery (the one inserted in the MB) and wait for about half an hour to be sure.

Ok so I bought a HP Mini Notebook for my wife Model NR Everything was working fine She goes to boot it yesterday and she gets hit with a password right after the AMI bios screen She asked me if I set the PW I told her no and she said she didn t either No big deal I take it apart and unplug the CMOS battery for about minutes Hold the power button down for a bit to discharge any left over juice Put it all back together and Unplugging battery work. BIOS doesn't CMOS password. same thing So I tried to leave it out for over hours and the same thing I even tried various AMI master passwords I knew it wouldnt work but you BIOS password. Unplugging CMOS battery doesn't work. know how desperate we get So now I m stuck I googled it today and found various information Most leading me to believe I am stuck with a paperweight or will have to send it to HP to have it fixed which will run me almost what I paid for it So am I missing something here Anything else I can do Thanks guys nbsp

I have a newer PC and trying to diagnose the problem. It was working fine for four months. I have had it turned off for nearly two months due to traveling and other activities. I powered it up and the Power Supply fan operates...the CPU fan operates...but that is it. Will not boot up. The hard drive light is a constant yellow (I know not all PCs have a light like this).

I switched out hard drives....same results. I've checked all connections but no help.

I hate to think a motherboard went bad on this thing.

Any help greatly appreciated!!!!

Whenever I power up this new machine (from being completely switched off from the back) the CMOS looses its contents, reverts to default and says "CMOS Checksum Error - F1 to Continue DEL for Setup". After that its fine (even if you don't touch the settings). Once you set the date time, it runs fine and retains its contents even on reboot or if you switch it off from the front (which I'm assuming is a standby mode cos the green LED on the board is still on)... that is, until you completely power off from the back, then it loses its settings - again!
I'm assuming its the little silver battery which is probably dead (weird considering its a new motherboard) but as I don't really keep up to date with technology anymore like I used to, I can't be sure. Can someone please confirm this?

Hello I have a desktop Dell Inspiron XP SP that was gaining time and dropping my internet connection often It's about years old so I figured it was replacing CMOS synch Time work battery tool after doesn't past time to change the CMOS battery and did so When I restarted I attempted to synchronize Time synch tool doesn't work after replacing CMOS battery with adjust date time It informed me that Windows could not synchronize for security reasons because my date did not match and to adjust the date and try again Sure enough I hadn't noticed but the date was reading So I manually adjusted to both the correct date and correct time and tried again and got the same message So then I went into BIOS setup BIOS showed both the correct date and time This isn't a big issue at this point I guess because the time in both BIOS and on my desktop are showing the correct date and time and I no longer seem to be gaining time or dropping my internet connection since I replaced the battery and I can manually adjust the date and time However it bothers me that I cannot seem to synchronize with an internet time server because it keeps saying that the date does not match I have tried various time servers including pool ntp org Any ideas would be very welcome

This is another case of factory bloatware interfering - in this case a useless factory utility overriding Win7's superior built-in version.

Googling the Quiet Office feature of Asus there are multiple reported problems. Best to default to the Win7 built-in Power Options in Control Panel. Set up a Balanced Plan unless you're a gamer then use High Performance.

Sorry for the length as I tried to make this as short as I could while giving what I believe is essential information Back in late - early I built a socket system running Windows XP The case I used Power Issues? or CMOS Something Else Causing Battery, Supply, was a Thermalrock which was a division of Thermaltake The case itself was well made but the start CMOS Battery, Power Supply, or Something Else Causing Issues? button was housed in extremely cheap material and through normal CMOS Battery, Power Supply, or Something Else Causing Issues? wear broke ever so easily the case was an expensive mistake So I was forced to remove the start CMOS Battery, Power Supply, or Something Else Causing Issues? button from its housing there was absolutely no way to fix When this happened the system would not start up when the now unhoused button was engaged I had to reach around the back turn off the power supply turn it back on and then press the power button It would then start but I had to do this every time Three years ago I built an i system and the socket with a few exceptions lay dormant since then realizing it is almost years old Last week my dad wants me to build him a system but I decided to see if these parts were serviceable Besides it would be better than his laptop that runs Vista and at years of age he basically only uses his system to do family research video streaming listening to online music and his favorite internet talk shows So I bought a HAF and I am going to upgrade him to Windows yes I have installed gigs of RAM I migrated everything over to the HAF and here is what I have run into no I have not upgraded to yet The CMOS does not appear to retain any of the changes I have made I e once had a floppy drive a long time ago but it shows it is enabled installed I disabled but on the next start-up it shows it enabled again so I disable again and on the next start up its repeat and rinse When the system initially loads it goes so far and then it stops and at the bottom it says Press F to continue and DEL for set-up every time It continues on to what I chose to load either Windows or it enters BIOS Turn on PSU hit start button nothing just like before One out of Blue leds on mobo indicating the board is powered is on Turn off power supply and then turn it back on press start button and system boots up but this time the additional mobo leds come on Then it proceeds to point The PSU voltages are all within normal I ran every Seagate SeaTools tests they have and the Hard Drive passed them all without any issues at all Your thoughts advice please on what I probably have missed need to try CMOS battery psu both and or something else Thanks nbsp

A:CMOS Battery, Power Supply, or Something Else Causing Issues?

I would replace the CMOS battery and see if the bios changes are properly saved. If not, the realtime clock chip is probably gone, meaning it is time to upgrade the CPU and motherboard. 939 boards may be extremely rare now

Hello. I'm new to this forum, and I'm not super experienced, so I hope I'm not overlooking something basic or don't understand something, but here's my question:

I set the "supervisor password" and the "user password" in the BIOS set-up in windows xp professional (pavilion a1010, p4). After turning off the computer and then powering it back up, I am not prompted for the "user password" (which is the power-on password, right?). I am, however, prompted for the "supervisor password", if I try to enter BIOS set-up, indicating to me that the CMOS battery is good. When I do enter BIOS set-up the "supervisor password" and the "user password" are still indicated to be "enabled". Any insights on why my computer is not prompting me for the power-on password would much appreciated. Thank you.

The system's fan was very loud so I put in a new power supply and then everything booted up fine. Unfortunately, that didn't solve the problem. It was the Motherboard fan making all the noise.

So, I put the old power supply back in and now the system doesn't power up at all. I checked all connections & I replaced the power cord and tried a different electrical outlet.

I even put the new P/S back in and nothing changed. It still doesn't power up. It's dead!

Any suggestions?

Do you mean the CPU fan ?
If so then I wonder if the CPU has been cooked

I would start by dispersing all internal voltage.
Detach the power cord
Press the power button in for 20 seconds
Re=attach the power cord
Try again

If it didn't fix then remove all addons, usb devices really anything attached (except screen and keyboard and power cord)
And try again

If it didn't fix then, confirm all internal connections are secure (even detach the dvd drive{s}

If it didn't fix then try disconnecting all fans (what !) for about 10 secs (turning on) I once had a fan of all things, that stopped my computer from turning on (unbelievable, I know)

Lastly, check the CPU for heat damage !

This is a first...

A friend was visiting for three days and a few things seemed to change. He shut off my monitor when not using the PC. It didn't come back on when I hit the power, so I hit the menu button and tried to get the thing up & running. I didn't get into the monitor's menu.

That's the only thing that was done differently. Now XP asks for the CMOS setting every time I boot up. It asks for standard (F1) or advanced (F2). When I do the standard setting, my computer starts back to the year 2002 at 12pm.

How can I get things back to normal, when I turn the PC on and it boots up in XP like always?

A:Doesn't Power Up

Can you move the suspect power supply to another box and test ? Can you move a good PSU to the failed box and test ? The PSU is the first component I would prove/disprove. (It would be better to test the suspect one on another, working box, as the failed box could have multiple problems which a good PSU might not fix and the results, therefore, could be misleading.)

After my friend's laptop wouldn't run on battery power OR charge the battery I tried many "fixes."
Shockingly none worked that I found.
Only one thing worked for me to my surprise.
A last ditch effort was to open up the laptop (sony pcg-81114L) and disconnect the cmos battery for a few minutes to reset the CMOS.
To my surprise, when powered on, the battery instantly showed it was charging AND when removing the power plug the battery POWERS the laptop now! (and I'd thought I was wasting my time.)
Worked with an off brand battery also.
Many times this has saved many computers that have odd "unsolvable" things wrong with them.
Surely someone else has done this also but I haven't seen it posted anywhere to my knowledge.
Thank GOD for bringing the idea to remembrance!

A:HP laptop doesn't power up

Some laptops won't power up if the battery is not working, but I doubt that's the issue in your case. So far I've only seen that on Medion laptops, and I own a HP myself - pretty sure it should work without a battery.

That is indeed a rather intriguing issue. Seems like you're stuck in a difficult position.
I would normally suspect some kind of hardware fault such as motherboard failure. It could be something much simpler such as faulty power jack, which I doubt since the little light comes on.

Here are my suggestions:

1. Try a different charger, was yours ever getting very hot?

2. Remove the battery AND the CMOS battery and do a hard reset, then plug the charger in (without CMOS or the laptop's battery) THIS WILL ERASE YOUR BIOS SETTINGS. Doing so on my laptop would cause it to power up without having to press the power button.

Good day all! Here's the scoop! I've installed WindowsMe last week. It froze all the time for various reasons. So I was reseting all the time, but two days ago, I had to shut it down with the power switch. I did that a few times because the reset wasn't reponding. So at lunch today, I tried to go to check my msconfig, but my computer remains off. I've looked at the cables, changed cables, no good. I think it's the battery in the motherboard, but I'm not sure. Thanks in advance for any tips!!

I moved my computer to a different part of the room and tried booting up and nothing happens. I took off the cover and noticed the blower fan (fan that cools the inside) goes on for a brief moment then shuts off and then nothing...

Could it be the power supply or power switch?


A:Computer doesn't power up

when you moved your computer it is very possible some wiring got displaced. i would open up the case. verify that everything is in order. the cables connected properly ect ect.

pay special attention to the power supply

GeForce6600GT AGP = Bullshi*

Hi, I'm having a little trouble with my GeForce 6600gt (club3d) agp videocard.

I first plugged it in, beeps. I noticed my Power Supply didn't have enough output for the card (put my Radeon 9600 back in, ordered new one)

Well, later I received a new Sweex 400W power supply.

The GeForce worked fine, until it complained about not getting enough power.


I unplugged my floppy disk drive, it didn't complain about it on Windows startup, but later, after playing some games it started to complain *again*.

Is this a trouble within the card or do I just need to get a new power supply (again)?

A:GeForce6600GT AGP - Doesn't get enough power

it could be a defective card or it could be the power supply yuo bought is substandard. all PSU's are not equal. many of them deliver less that HALF of what their ratings say once they have warmed up. that is why it is best to buy a good brand name PSU, like antec, Vantec, etc.

Hello folks.My elitebook worked perfectly until one morning when I turned it on. On pressing the power button, the power indicator shows a white light, then the WiFi LED comes on (red and quickly changes to blue) and the HDD indicator comes on (red). The WiFi indicator also comes on. After a few seconds, the sleep indicator comes on and the laptop goes off. No display, no hdd sound, no fan sound, just the above. Please help me out.Thanks!

The puzzle.
The desktop doesn't power off at shut down from Windows 10.
Shutting down from Puppy switches everything off.
Like what it used to do.
The procedure has been to pull the power cable from the pc and then back in.
After System shuts down.
For next time...
But Puppy turns it all off.
Go Puppy.

I have a Dell 1905FP, and I want it to power down automatically when my computer goes into standby mode or powers off. Instead, the LCD floats a standard status panel, similar to what I get if I unplug the video cable with the LCD still powered on.

I'm certain there's a way for the computer to send a power off or "green mode" signal to the LCD, but I'm not finding anything helpful...

I have this motherboard whose identity I havent yet been able to discover but basically it doesn't power up. It has a P-iii 450MHz CPU and I have verified that the CPU and power supply are good. What I found was that the power LED would glow and the CPU power fan would rotate for a 3 seconds. I took out the CPU and the LED/fan were on for 5-6 seconds longer but then went dead. Problem with the capacitors ??

What could be wrong ? Any help would be appreciated.

I don't work much with laptops, but power related issues are generally a motherboard function. If a laptop boots with/without a battery, or with/without AC connected, it typically implies a motherboard malfunction.

The mute and wirless LEDs are solid (wireless LED is amber and the mute botton is white). The fan spins for a second and then it goes out.I've unseated/reseated the hard drive and removed the wireless module.

A:Satellite Pro M60-164 doesn't power up at all


It seams that this has nothing to do with power mains but with an internal hardware problem on the mobo.
I think you should firstly check the both memory modules inside the notebook.
If the notebook would not power up even using new modules, then other parts like CPU or motherboard should be checked.

Sorry but this is everything what I could suggest you.

A:Computer doesn't power up immediately

There is a jumper you can reset so you don't have to remove the battery for 5 minutes every time.

I don't know what the problem would be, but it is easier to replace or try another PSU than it is to replace the motherboard.

I have a Dell E310 with XP in which I just installed a VisionTek X1550 PCI graphics card. The card seems to work fine. My issue is that since I installed the card, the monitor will not turn off when my computer tries to go to Stand-by mode. Instead, the Dell Self-test Feature Check just slowly migrates across the screen. I believe the OS is sending the signal to turn off the monitor because the STFC would only appear when the monitor no longer detects the graphics card. So it's like the OS is shutting down the graphics card, but the signal doesn't reach the monitor to power it off (change the power button from green to amber and set the screen completely black). I would really like to get this working again. Does anyone know how to correct this? Thanks!

Hi everyone,

my almost new Portege Z30 doesn't start anymore. There is only one white light flashing - the one for DC/battery - but other than that: nothing happens :(

What can I do?
Thanks for your help and support.

A:Portege Z30- A-1FL doesn't power up anymore

Sorry to hear that?

Portege Z30 is very nice, good looking Ultrabook and as far as I know the notebook?s battery isn?t removable. Therefore the common workaround like removing the battery and pressing/holding the power button 30 sec long isn?t possible.

Anyway, I guess that notebook?s hardware started to malfunction and the fault localization will not be very easy. Usually the notebook engineer would use a special test and diagnostic software in order to find out what could be exactly wrong.

From my point the issue could be related to memory problem or motherboard malfunction and I guess both parts should be checked for possible issues.

I'm looking into why my son-in-laws Vaio VGN-FS115Z laptop doesn't power up. Would appreciate any pointers.

Have done all the obvious (reseated CPU, removed etc memory, run with power supply, checked out HDD elsewhere).

Symptons are :-

Power button works , turns machine on and off.
No backlight, no screen, no Bios beeps (even if you remove memory etc)
3 leds (Caps lock / Numlock / Shift lock) all stay on.
All chips get warm after a while.
No sounds (beeps or otherwise)
CPU fan doesn't seem to start up - not sure if it needs the CPU to get really hot first, though.
Almost as if it's lost a power line, or CPU is dead, but drive, battery, mains, wifi leds all come on and appear to work fine.

Any pointers gratefully received...


A:Sony Vaio doesn't power up

I've seen this on your identical model of laptop during a service for a client. We RMA'd it back to SONY and they ended up replacing the motherboard. At least that's what the cryptic service notes said when it was returned.

In my own technical opinion though it doesn't look good. When your motherboard doesn't respond at's never a good thing.

Hey everyone,

My computer powers up, but nothing happen from there. The screen stays blank.

I took a look around and everything seems to be connected correctly. However, the CPU is stuck to the bottom of the CPU Cooler (Not sure of this is normal, or if the CPU has overheated and melted).

I've tried switching RAM, so that's not the problem.

Does anyone have any ideas what it could be? Also is it normal for the CPU to be stuck to the top of the cooler?

A:Computer power up, doesn't boot

Yes, the heatsink/fan assembly can be "stuck" to the top of the cpu by heat transfer compounds.

Re non booting, do you have any more detail, such as odd things which may have been happening prior to the pc failing to start. Also, confirm nothing is appearing at all on the screen - no post text. Has anything been changed prior to this happening.

Hey there everybody.
I have a 2 year old desktop running Windows 7. It's worked perfectly, and was working perfectly when I left it last night. This morning I was surprised to find it shut down. When I turned the power on, it lit up like it's supposed to, the fans engaged, but I don't think I hear the hard drive spinning. The hardware on the desktop itself is functioning (the DVD tray opens, for example) but there is no output to any devices, so the monitor doesn't come on, the keyboard isn't on, etc. I've tried the obvious fixes (removing and resupplying power, checking external connections).
Any help is greatly appreciated. Thanks for taking the time to look. Sorry if I haven't included required information, I'm very much a layman.

A:Desktop has power but doesn't boot

The first step would be to eliminate any plugin cards and the drives.  Both 12 and 5 volt supplies are needed, but the 12 volt is mostly for the hard drive and optical drives.  With just the MOBO, onboard video if available, and keyboard to start.  If no display, the CPU is not starting.  I suspect the power supply is faulty.

Have you tried grounding it, sometimes computer can short out when powering due to the motherboard touching the case, e.g. one of the screws are loose and move. You seem exsperienced so i would advice taking it out and plugging it back in on cardboard which will stop any power shorting out.

Would appreciate suggestions as to what may have failed and why First the background My infrequently used year old Dell Dimension XPS T desktop computer and Trinitron monitor have been doesn't or boot! power off Desktop plugged into an APC surge protector for a while now When I d go to use my PC I d simply power on the surge protector and then press the power buttons on the CPU and monitor to turn them on and boot up the computer Now the Desktop doesn't power off or boot! problem Earlier this week I turned on the surge protector and the computer powered on automatically didn t need to press the power button then proceeded to run through it s usual sequence - checked the DVD drive then the CD drive but stopped there The light on the floppy drive didn t come on and the computer didn t boot yet the harddrive light came on and stayed on for about seconds then turned off The CPU fan ran OK Though I had no problem powering the monitor on or off I am unable to power off the CPU or get it to boot - it isn t responding The only way I could power off the computer was to unplug it Initially I thought the surge protector was the problem but plugging the CPU and monitor directly into a wall outlet has produced the same results I also attempted to boot the PC using my MS Windows boot disk and Dell Dimension support CD but the floppy drive isn t responding reading the disk I ve read some of the other threads in this forum and am thinking I may have multiple problems - floppy disk power supply etc but don t know what my next step should be to investigate the problem I know the computer is almost years old but I like Windows and I paid for the computer and would like to fix the problem if it s cost justifiable I was told by a tech at Staples Business Depot that I should just chuck the PC and buy one of their cheap desktops for but what kind of PC would I be getting for that price Could use some expert and sensible advice here Anyone Thanks - Euridice nbsp

Hello guys and gals,

I have a situation! I bought a HP Pavilion 4535 and I'm in the process of fixing it up! I recently installed a new hard drive 30gigs and installed WinXP. It seems like everything else works fine except the power supply! As soon as I connect the power cord to the power supply the fan begins to run and I havent even turned the PC on. It boots up just fine, does not overheat or anything but when I shut it off I have the same problem that the fan does not shut off! If I leave the power cord attached the fan will continue to run. I'm not sure of what this problem could be, so do any of you all have any suggestions? Should I get a new power supply? Thanks for any advice.

Me again.

I have one of the strangest issues I have come across. After upgrading to 8.1 my power button doesn't always work when trying to enter sleep mode. It's how I send my computer to sleep and wake it up. If the computer is off or asleep and I press the button it works every time, but if it is on and I press it to send it to sleep mode it works probably 25% of the time.

Not sure what specs will be useful so here are the main things: custom built computer inside a "Cooler Master Storm Enforcer" case with an ASRock Z77 Extreme6 motherboard, Intel i7 3770k, and Windows 8.1 Pro w/ media center.

Also as a side issue (that has been going on since before Windows 8.1) when I right click a word in Chrome to auto correct it that only works once per text entry. If I click the new word on the context menu nothing happens.

Hi there,
My computer is a custom build and I've had it around 4 years now,
About 2 months ago it stopped turning on fully, it'll power on and all the fans are running but it won't connect to the screen.
I was told it was the power supply, so I got a new one and still nothing.
If anyone could help, i'd be extremely grateful!!

BTX Pentium D running XP Media Center activates fans but doesn't boot when powered on. Was running fine, turned off overnight, now will not boot. 4GB ram installed, tried with 1GB, 2GB and 0GB. No beeps when powered up with 0GB.
-Tried integrated video connected and video card connected with no luck.
-Replaced motherboard, same issue.
-Also tried different processor when new MB installed. Same results. Went back to original Pent D.
-Fans run full speed all the time.

It was the power supply & the MB.

I have an emachine comp that has always had trouble restarting. If I try to restart it it gets stuck at the e machines logo. I have always just shut it down and then rebooted to avoid this. Now it gets power after I turn it on, all fans working, hard drive running, cd drive running and everything but the monitor gets no signal. I tried to start it many times but just ended up with the same results until now. It is running fine again all of the sudden with no change at all so obviously it is not the monitor. Does anyone know about what causes this to happen? I am afraid I will be stuck with it just not starting at all at one point if I don't find out what is wrong.

Thank you so much for your help!

A:Comp has power but doesn't boot every time

I had a long reply and it got lost completely so to narrow this attempt down...
Check for connections at the terminals, also dust and corrosion over time, as well as spotty HDD things like reading errors via blemishes on the discs surfaces can cause delayed reading. It's the same as most other electronics's symptoms in this regard.
That's my opinion because you can't see what the CPU and computer are actually getting stuck on, however, if the HDD light is constant, assume it is a read error.

Also, you will have extra AGP or PCI only slots, add a back up video card to insure you have a fall back! The onboard video connections can fail due to the cheap overall construction of eMachines' Mobos (TriGEM)

The power adaptor for my NTL cable modem doesn't work anymore. I know this because my modem would no longer power-up so I swapped the power adaptor from my speakers to my modem and my modem worked! So, I was wondering, where do I get another adaptor? Or is this up to Virgin Media to replace?

Note: It's a 10v OEM AC Adaptor.

Let me know if you need the model number etc.

I just did a fresh install of Windows home ultimate bit and I am pretty doesn't save turn Power sometimes off monitors sure this problem started right away I have an NVIDIA GeForce with a dual monitor setup - HP LP w connected Power save sometimes doesn't turn off monitors via DVI and a Samsung Power save sometimes doesn't turn off monitors Syncmaster connected via VGA The problem is that when the system has been idle long enough and the monitors are supposed to power off about half the time unpredictable although the monitors go black they don't turn off the backlight is on and the power LEDs show they are on Both monitors show the same behavior at the same time e g either both will power off correctly or both will fail to power off so the problem isn't monitor-specific Back when I had XP on this same setup I didn't have this problem Anybody experiencing a similar issue or have any ideas what might be the problem here I started with Windows standard drivers but them installed NVIDIA's drivers but it made no difference Windows home ultimate -bit Athlon GB NVIDIA GeForce

A:Power save sometimes doesn't turn off monitors

I think I found the problem - it's the Google Photos Screensaver included with Picasa 3. If I don't use that screensaver, the problem never occurs.

I've had this issue for quite a while with my HP Split x2 now where you'd simply try shutdown Windows, however after it has shutdown you get the blank screen, but it does not power off the machine.

Recently (in the last week) I've had this issue happen to my main computer too which is a custom built PC, either since an update or from an unsafe shutdown, not sure which.

The only fix for this is to turn fast shutdown off which solves the issue on both my laptop (HP Split x2) and my PC. There should be a better fix for this though. So is there some steps I can take to diagnose it or to see if any hybrid files are corrupt or such? I have a feeling it is a hardware issue with my HP Split x2 but it's extremely unlikely that my custom built PC has hardware faults too.

Both machines are running Windows 8.1 Pro.

Hey, i've got a major problem, probably motherboard issue, so i'm posting it here, to make sure it's my motherboard.

-When i turn on my computer, it does really nothing, even the power light on the front isn't flashing, only the one below (there are two LEDs outside) blinks once! Then it turns off.
-When i remove every other hardware (Except the ones inside the comp.), same happens.
-My computer is connected to the power cord, and when i start up, i clearly hear the fans.

Thanks for helping.

A:Computer doesn't start, and no power light

first thing to try would be to swap power supplies...

if new power supply works, then the old one is dead
if new power supply doesn't work, then the motherboard or CPU may be dead
memory may also be preventing the computer from starting, so remove a stick

if you are using an internal speaker, does it beep in pattern or nothing at all?

I would greatly appreciate help with my problem. My PC, an Acer Aspire AM5641-U5630A with Windows Vista, only starts up sometimes. When I press the power button, the blue power light comes on and the fans start sounding. However, after it quiets down there is no beeping noises and a display does not come on. On times in which the computer does turn on, a beeping noise is heard and an Acer logo display comes on before it proceeds to start up like normal. Once I'm past the Acer logo the computer works fine. It seems to be random as to when it powers up but I have tried an upwards of 20 restarts before.


A:Computer only boots up sometimes, power light on if it doesn't

This is most likely caused by a weak or failing power supply. Open up the case and make sure that the fans are running and everything is free of heavy dust and other debris...

Hi guys,

I installed a new CPU-Cooler (Scythe Mugen 4) on my computer and to do so had to remove my mother board (A88XM-E35, socket FM2+) and graphic card (R7250-OC-2GD3) from my computer. After putting back the mother board, with the graphic card and CPU-Cooler attached on it, my computer doesn't power up anymore.

I have been trying to fix this problem for several hours now but I am unable to do so. My first thought is that I didn't connect the mother board or graphic card back correctly, but I am unable to find the issue. Could anyone help me and try to guide in me in finding the issue?

A:Computer doesn't power on after installing new CPU-Cooler

Go back over ALL of the connections again. There are 2 power connections to the motherboard, the 24 pin and either a 4 pin or 8 pin CPU power. The video card power connection. Those are the only basic ones needed for it to power on. Obviously power is needed for the hard drive to boot up, the ones listed are all that is needed for the motherboard to power up and be able access the BIOS.

On startup, I have the power meter icon start up in the notification area but when the computer does startup, it doesn't load. If I were to kill the explorer.exe process and relaunch it, the power meter will load up.

Does anyone know how to fix this problem?

A:Windows Power Meter doesn't start

The Power Options, of which Power Meter is a part, is a Control Panel Extension named PowerCfg.cpl and the main entry resides in C:\Windows\System32 folder. Perhaps it is corrupt.

What you could try is to boot to Recovery Console and expand your disk copy of that .cpl into the Windows32 folder.

While you could force delete it the cache copy might be bad also.

If it works after that, replace the cache copy also.

Hi there, I've just built my first PC... everything seemed to be going well until power up!

The switch on the back of the PSU is on and the motherboard led lights up to show that it's getting power. When I try my power switch nothing happens, I even got a cheap motherboard testing kit with a little power switch in case the one on the case was loose/knackered, still nothing.

It didn't blow or bang or do anyting upon first power up. I'm pretty sure the PSU is connected to the 24pin and 4pin slots on the motherboard correctly.

There's literally nothing upon power up though, no fans, no hard drive spins, nothing.

Motherboard problem maybe? Power getting to it to turn on the LED but problems elsewhere?

Any help would be greatly appreciated as I'm slightly worried I've just thrown 500 down the toilet!

ok so my computer's screen stays black, but the on button lights up and i can hear the windows welcome noise, so i know its on. i think i know why this is happening, because i recently messed with the power settings and changed the option to go to standby when the laptop is not running on outlet power. so i realized that i need to just plug it in, but now it doesn't respond to the outlet power. usually a little lightning bolt lights up on the comp when it's plugged in, but not anymore. can someone please help on why this is?

I have screensaver off in Win 8, now 8.1, but in power options (high performance) I've set the monitor to turn off (go black) after 20 minutes of inactivity. Normally, when I come back to the computer, tapping the Escape key brings back the desktop in short order. However two times lately, one about a week ago in Win 8, the other just now in 8.1, there's been no screen response and I've had to shut down the computer and reboot. It's the monitor not responding, not the computer, which for example just now was still playing music at Spotify when I came back. I assume it has something to do with power options, but I can't figure out what. Any ideas? Thanks,

Hello iron200 and welcome.

Looks like you're having some trouble with your Graphic Driver. Try this (if possible).

1) Make your way to Nvidia - Drivers and get the one for yours

2) Uninstall the one you currently have and all the extensions (PhysX, etc)

3) Download Driver Sweeper

4) Get to safe mode (without network) and search for Driver Sweeper in your Start

5) Select all Nvidia components and analyse them

6) Clean them, head into Windows

To avoid Windows from downloading the driver it recommend, go into Windows without internet. Either plug your LAN cable out, or if you're on wireless, turn it off for just a moment until you got the new one
When you're in Windows, find the driver you downloaded on the first step. It might be in your /downloads - Install it

Carry on.
