LCD doesn't power down with computer

Q: LCD doesn't power down with computer

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...

Preferred Solution: LCD doesn't power down with computer

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 http://downloadreimage.com/directdownload.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Right click on desktop -> properties ->screensaver ->power.. -> turn off monitor

select the same time that your pc idles before it either powers off or goes into standby.

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?

Thanks
 

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

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!!

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.

not sure how it turns slightly on. but your power supply may be bad. thats the cheapest fix. the motherboard will be the worst case scenerio.

Hi guys I ve had this problem with my PC now for the last few weeks When I power up my computer it doesn t switch on immediately and didn t come on until around mins later This mins then doesn't power up immediately Computer became mins When the computer did power on however everythign was fine and I could access all my files etc properly I suspected that it may be the PSU or MB I opened it up and first took the MB s battery out and then put it back in again after mins This didn t do anything At this point I had brought the computer downstairs Then I decided to make sure the whole tower was free of dust etc and then try it All of a sudden it started to work correctly i e I could switch it off and then when I switch it on again it would come on right away I Computer doesn't power up immediately took it upstairs again and the same problem started again During Computer doesn't power up immediately all this however the motherboards green power light is always on and I can t see any warning lights or obvious areas of damage to it My dad then took the battery of the MB out again and put it back in again and then it started coming on immediately again However I went to try it again and guess what it s not powering up at all now again What do you think may be the cause of this Is a new PSU in order When I manage to get into BIOS In the Hardware Monitor section the voltages are all indicated as being correct i e where it says it should be it is and where it says it is etc The CPU s temp is around C and the motherboards is C I havent installed any new software etc and dont think I have any viruses as I hardly have anything on my computer as it is But I installed a Netgear USB Wireless device which kept hanging forcing me to keep on having to switch my computer off from the power button as opposed to shutting it down through windows I have since uninstalled this Your ideas suggestions will be much appreciated Thanks Sukhraj Intel P GHz Asus P S X MB MB RAM Windows XP IDE Gb HDD nbsp

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.

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!!

Hello friends,

My old computer (Intel Impression 440BX) was running Win98, I formatted and installed XP Professional. Now when I select shutdown, the computer no longer turns itself off - as it used to. I now get the "It is now safe to turn off your computer" screen and have to manually turn off the power to the Motherboard.

I didn't make any changes to BIOS (AWARD) and I looked around to see if XP changed something, but didn't notice anything. I am not that experienced with all the different BIOS settings.

Thanks for your help.

Hello,
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.

Thanks,

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.

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'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.

:knock: Today I came home from work and pressed the power button on the computer to which nothing happened. Not a slight power up and turn off, no lights fans, no sign of life. I used it this morning with no problems or indications of anything being wrong and turned it off when I was done, which it shut down properly. It never just turns off in the middle of gaming or anything. What could be the problem with it? Would that be the power supply? I have it plugged into a good surge protector and there was no lightning of weather effects today while I was gone. I turn it off every night before sleeping and when ever i'm done with it. Anyways, thats some usage of it. Its usually on for 6 hours a day or so and its rufly 3 weeks old. (just built). Thanks for any help you guys can give!!

Jason - from what you describe (and assuming your power outlet is OK), your computer's power supply may have blown. Thankfully, it is an inexpensive part to replace!

After a power outtage hit my house I tried to start my computer, but it didn't turn on. I opened the computer up thinking it was the power supply. I had the power supply replaced but that wasn't the issue. I also noticed the modem on the motherboard was lit up, so im guessing the motherboard is still ok. Sometimes when i kept turning off the power supply then back on, then try to start the computer i would see a flicker of the power light. Please i need advice on what could be wrong with the computer before i waste money to get it repaired when it could be a easy fix that I can do.

Greetings all,

This is my first post. Let me try to explain this as much as possible. I've been having this problem of when I first start up my computer the fans start spinning but the computer seems to start and then shut off like it has a short. Almost like a wire is loose touching and then not touching. Once it goes thru this for a few minutes then it will fire up all the way and run fine. I've gone back into my case and made sure that all cables were securely connected. Removed and reseated the memory in different slots as well as the video card. I'm thinking about removing the cpu and making sure that the pins are fully connected too.

Could this be a sign a my power supply about to go bad? What are your thoughts on this? Thanks for listening.

Hi!

My Vista problem is this:

I unplug AC and USB devices in order to work outside my working station...
After some time, when I replug the laptop to AC and replug the USB devices they don't work... No mouse, no printer, no smart card, no usb at all. Also I can't restart the computer as it freezes, so I have to shut it down "violently". I noticed that this always occurs when the battery is under 50 %. But sometimes it happens even at higher percentages. I've installed sp2, I've disabled the USB selective suspend both in power options and in registry... WHAT ELSE TO DO???
Thanks!!!

Hi ogi30 and welcome to Vista Forums

What happens if you shutdown your laptop before reconnecting the adapter and USB devices? Does it then restart correctly? How old is your laptop, and, more to the point, how old is the battery?

Suggest you go back to basics, and test then add one component at a time.
It appears you have the knowledge to think this through and get it up to speed. You probably have two or three problems which will not make it easy to trouble shoot.
Make sure you are rested, then make a lot of notes.

A:Computer fails to boot, Monitor doesn`t power on and constant beep follows

Seems your system is signaling an equipment failure at the POST (Power On Self Test). Is the beeping a single continuous beep that never ends, or a series of individual beeps that just keeps going?

Also, knowing the brand and model of the computer, or if it's a generic build, details of the motherboard, video card used, will help in diagnosis.

A:Built new computer, normal fans work, but CPU fan doesn't spin, board wont power

Sounds like a power supply problem, or a error in connecting a cable. Thus the shot spin of the cpu fan. But usually you just missed something too obvious to think about.
Reseat all cables. Reseat all memory modules. Then try it with one or two memory modules at a time. Then switch to the others.
Check your CPU for proper seating, and possible bent pin.
When no longer frustrated, think through everything you have done in the setup, even the heat sink and thermal paste.
We have all gone through this. We know has exasperated you must feel.

I have an ASUS notebook running windows 7 64-bit. I am using the QuietOffice power profile, however the screensaver won't kick in no matter what I do, and the display does not turn off even though I set it to be after 5-minutes of inactivity. I don't know if there is something running in the background... I have turned off my usb wireless mouse, and nothing....

Any ideas?

THanks.

A:HELP: power option doesn't work - screen saver doesn't start!

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.

Here are other tips for cleaning up factory bloatware

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 !

For the last month or so, every time I log off my account, the keyboard does not register at the Windows Log In screen. This makes it so I have to restart the computer and then it works fine.
There are three accounts on the computer, the casing has been half removed for the last 3 months, a DVD burner and driver recently installed 3 months ago and I am using a wireless off brand USB keyboard and mouse.
OS: Windows Xp Home Edition 5.1.2600 Service Pack 3
As for the second part, the computer requires several restarts to boot up, sometimes up to twenty minutes of turning on and off to boot up. Only started doing this a week ago.

A:My Keyboard doesn't work, and the computer turns on but doesn't start.

It sounds like something is wrong with your Windows XP drivers. Something like that happened to me while building my computer, and when I boot up the keyboard did not work because my copy of windows XP was bad. You could try reinstalling windows XP, and It might work better, but I dont have a definite answer to your problem.

I have an HP Pavilion 8562 I just bought off someone. It came without the HD, but with all the other original componants. When I hit the power button nothing happens, the light might flash, but the power supply does not start up. When I got it the big 8-pin thing was oput of the mobo, but I plugged it back in. It will not scan thdrives, or go to bios, or even make any noise or bring anything up on the screen. Assuming it is not dead, any suggestions? This is why I hate manufatured computers.
 

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.)

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.

How?!

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.

The green like on the back of tower was solid when power cable was plugged in. It would turn off in couple seconds after the power cable is detached. I have read through the forum and most of people's problem was with the PSU or MB. Any idea what could be the problem in my case? Or anywhere I can go to have someone troubleshoot my PC for me?

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: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.

A:Board doesn't power on

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.

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

Hi

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.

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.

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.

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.

Despite this the monitor is always turned of after a while.

Is there a way to save my power options so that the monitor is never turned off?

Thanks

Hello Aperture,

If you are sure you are saving your changes before closing the windows, perhaps it is another program interfering. For instance, do you have any power-saving programs that came with your machine?

A:Micro ATX system doesn't power up

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.

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.

Hi,

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...

Cheers,
 

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 all...it's never a good thing.

I am fixing a PC for a friend; their power supply went bad, so i switched it but now the PC will NOT turn on using the front PC button but rather it turns on when i plug in the cable in the Power Supply.

& Furthermore, it shows nothing on the monitor when it turns on...

The Power Supply Fan is working, CD Drive open normally & i can hear the Hard drive moving...

Can you guys give me a bit of advance on what i should do next please?

Are you sure you plugged all the connectors correctly? The PC not switching on from the front button would seem to indicate the power switch is not plugged into the motherboard.

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.

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 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!

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.

Hi,
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)

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,

A:Unseen BSOD after shut down, PC doesn't power down

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



   Tip
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.
Frederik

As I was reading it almost near the end the guy found out what the problem was and it was bad. He said the motherboard was touching the metal inside the tower and that that way u can fry ur motherboard in secs and that's what happened to him along wid few other things connected to it. When I read that I almost got a heart attack and felt like shyt since my PC is worth some big bucks and I just bought it 6 months ago. So widout any hope left miserably feeling I unscrewed the motherboard and I have used the plastic dunno what to call it (screws) to hold up my motherboard in the air. And for the last time I decided to press the button knowing it won't work. And guess what everything turned on and I almost shyt myself instantly from the shock and happiness and almost wanted to cry. I don't know what saved me, why my motherboard didn't fry but I know I am lucky as hell like never befo. I turned on my system and eveertyhing seems to work well other than the fact that norton antivirus cant load up it's driver and my date was resetted to default but that's it for now.

A:Windows doesn't start after disconnect power

Each O/S is on a separate partition.
 
That means that one partition may have bad clusters or some other hard problem...while the other does not.
 
The boot files for each O/S are also different, so a problem booting one does not equate to a problem booting the other, IMO.
 
Beyond that, I can't generalize.

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.

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!

Thanks

When I turn off the computer, be it by pressing the power button or by the turn off option in the start menu, windows closes normally, the screen goes no signal, even the hard disk and power leds turn off but the fan in the power supply keeps spinning.

All I can do then is keep the power button pressed for a few seconds and finally the power supply stops, or press the reset button to start the computer again or click the power switch of the power supply in the back of the computer tower off and on (when clicked on again, the computer keeps turned off)

I had Windows XP in the same computer and it turned off normally. In fact, if I boot in Windows XP (it still is in another hard disk inside the computer), the turn off sequence works normally so it looks like a software problem, not hardware.
