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.)

I very much doubt it's a Bios problem.This may or may not work.Remove the power cord and battery, hold the power button down for 60 seconds. Plug in and try.

A:My tower Power button will not work

You could have a defective power switch on the PC case. Test this by using the reset switch as a temporary power switch. The power switch and the reset switch are the same for practical purposes except, of course, the size of the button (on most cases). If the reset switch works and is able to start the PC, then you know the power switch is defective.

I have an older eMachines Desktop PC model EL1360G which has a 200 watt power supply.
I would like to upgrade it to at least a 400 watt power supply.
Does anyone have a suggestion as to where or what I should buy? I watched a few videos on youtube on how to do the replacement but how do I know all the plugs on the new unit are the same and will fit? Because if they don't, I'll be more confused than I already am.

1x 4pin (P4)

2x SATA power
Does your power supply have these and only these?

My Friend has a HP Pavilion DV2000 Laptop. His display isn't work. Suddenly display gone. But I thought it could be Display problem not a VGA. So, i tried to connect an external monitor and used Shortcut keys to change the display. I pressed fu + F1 or Fu + F2 or Fu + F3 or Fu + F4 up-to F12. But no result.
I couldn't check whether it's a Display or VGA card problem. IS there any other way to check it. in addition to these is there any other combination keys to Change the display to an external monitor. I'm unable to check whether i get login or not. if I can login then i can use Windows Key + P. Then i can select mode. But I'm Unable to anything here. Please help me to find the problem and i have to take it to repairing shop.

Hello,

I have been using the same set up for just over a year now and yesterday my monitor (which is just a TV with a HDMI port) stopped receiving signal.

I can boot up the pc and get the BIOS, which I can go into and see everything fine, as well as the windows loading icon but when it would normally go to the log in screen I get nothing.

I can however plug in an extra monitor (an actual Samsung monitor) with a VGA cable and it all works fine and on top of that if I connect the TV at the same time it works perfectly fine as a second monitor.

However if I try to turn off the VGA monitor and just use the HDMI TV then I get no video signal again.

No idea how to get my main TV monitor working again. Totally stumped.

Hi guys, new here...I'm setting up a new pc, sooo a few questions here.
I'm planning on getting an Asus A88XM-plus motheboard, Amd X4 860K cpu and Sapphire R9 280 3GB video card...so how much power supply would be enough...450-500W?..would 650 be an overkill? Is all of this fully compatible?
Do I need a sound card, modem or special cooling or something? ( I already have 2*8gb Ram sticks and HDD, don't really need DVD drive).
I'm also thinking in between Antec 902 V3 case and a lot cheaper LC Power Gaming 975b Air wing Midi...how much quality difference is there in between these two?
Also, how much improvement is there in between this card and my current one, sapphire r7 265 2gb?
Are there anything that you would exchange for something else...I'm on a tight budget, but I don't mind spending a few extra bucks if it be worth in the long run.
Thanks in advance.

I have uploaded a video of my laptop to better show the problem:

I am thinking something is wrong with a connection or some cable just don't know which. Never fixed a laptop. I broke the panel before I figured out the screws were hidden behind tiny black covers. Also broke the metallic part of the screen on the right side but I guess I will crazy glue it somehow. My most important issue is the flickering.

If anyone knows how to fix this issue please let me know I would really appreciate it.

At certain position the screen doesn't flicker, mostly if it's set back at a greater than 90 degree angle.
 

A:Laptop display flickers

It's sensible to check the connectors to the screen but unless you find a video of how to get inside your particular laptop and study it you are highly likely to break other pieces too. I worked out how to take mine apart thanks to Google but although I was careful I still broke a connector. Putting that right took me ages.

Here's the situation. I have this old mITX computer I built a few years ago that I'd like to hook up to Dad's big-screen TV so he can Skype from his living-room. Problem is, the computer is VGA only and his TV is HDMI only. The MoBo has just one PCI (not PCIe) slot with a maximum output of 75watts.

I tried a PCI video card with HDMI output, but the slot couldn't drive the card. Didn't even detect it.

I believe DVI uses less power (the cards are definitely cheaper), and I could just use a simple DVI-to-HDMI cable. A native HDMI port would be better. As long as it works, I don't care. But w/o an external power input, the card can't draw more than 75watts from the PCI slot.

Anyone know of a card that fits this very specific bill? Thx.

ADDENDUM: PC only has a tiny 300watt PSU.
 

A:I need a PCI (not PCIe) DVI card (either <75w or w/power input)

Check this one out: Zotac GeForce GT 610
It is a PCI Card (non express) that has DVI / VGA / HDMI. It is also a Low Profile and requires a 300w power supply or higher. It looks like it should work with your situation.

I recently moved my computer from one side of my desk to the other and somehow it managed to make it so when I press the power button nothing happens. I've disassembled and reassembled the computer numerous times and tested the psu. The psu is working and it seems like the motherboard is the culprit. What is confusing me the most is that when I short the 24 pin connector to the motherboard then plug it in if I also press the power button I can turn on the computer. I dont see that as a permanent fix just in case it sleeps and I assume it is not good for the computer so I am looking for help on how to permanently fix my issue. Thanks in advance.

I could use some advice. My second monitor just died, and I would like to find a replacement with a few specific features.

27 inch
Adjustable White Point
As low as possible wattage

As I understand it, having a white point that is adjustable separately from brightness and temperature controls provides a better way to dim the white without dimming other colors. If I am not understanding this right, please correct me. The reason for looking into this is because of my eyes being sensitive to light. If I could, I would replace all white that comes through my monitor with a light tan. That's how bad it is. So, if there is a way I can better adjust how bright the white is, I'll probably take it.

The low power I want for reduced heat. With two screens this size, heat is obviously a problem. So far, I have only found that reducing wattage will have a noticeable decrease in heat. If there is something else, feel free to clue me in.

Thanks all!

HI, I was wondering if it is safe to use an atx psu on a motherboard with an eatx power connector. The motherboard has a 24-pin eatx and a 4-pin atx 12v connector. I bought the motherboard and started using an atx psu and everything seems to work ok then realized after it was an eatx power connector on the motherboard. Are there eatx psu's? Thanks
 

A:Safe to use ATX PSU on a motherboard with an EATX power connector?

EATX is a form factor (12"x13") not a power connector. I'm assuming you are talking about using a PSU with a 20 pin (old ATX) connector with a newer motherboard that has a 24 pin (current ATX) connector. If that is the case you will need to consult your motherboard's manual. Some 24 pin boards run fine with only 20 pins some don't. The issue is that each pin in only rated to carry a certain amount of current (Amps). If you overload one of these pins your risk burning or melting the ATX connector on either the PSU, Motherboard, or both.

If necessary I am able to disconnect 1 HD and the optical drive as they are not necessary, also to disable the onboard graphics if possible if this will help.

A:My laptop HP G61 does not power on

Perhaps you have one of those infernal HP laptop motherboard problems? How old is your HP g61, and have you kept the cooling channels free of lint and dust? How old is the hard drive?
Since it doesn't work from a battery or from wall power, you should have an experienced tech take a look.
First thing I would do is remove the hard drive, so you can rescue the data if need be.
Then I would remove the battery, and try again from the Mains. If nothing, then there is some real work ahead. Consider this a major failure in that case, and get expert help to take a look.
I doubt there is a quick fix.
Please keep us informed as to what you learn and what helped get your HP G61 back up and running.

I came home one day to find that my monitor was no longer displaying my PC via HDMI. After a lot of testing, I've found that the monitor works with other PCs via HDMI, and my PC works with other monitors via HDMI, but they don't work together. All I get is a black screen. I know that my PC's resolution is set to one that my monitor can display. I've tried several different cables. I have absolutely no idea what the issue might be, and I'm pretty much at my wit's end here. Any ideas?
 

A:Strangest display problem I've ever had

Have you tried different projection modes? Windows will remember set profiles for specific monitors. It is possible the the projection mode was turned off for the monitor, and will stay that way until the mode is changed.

For Windows 7 press "Windows Key + P" to bring up the projection menu.

Hello,

I remote into my home PC from work using the Chrome Remote Desktop tool. It works well. The problem is the screen resolution. The monitor I use at work isn't the same as the one on my home PC. This causes the resolution to be a little blurry and images to be slightly small.

When I disabled my monitor completely at home, the resolution was clear and it worked well. I just unplugged the monitor from my PC. Is there a way to completely disable a monitors input without having to physically disconnect it from the PC? I've tried disabling it in the Device Manager and that didn't do the trick. Any suggestions?

Thanks,

Speck

I know we had a thread on this in April of last year but what I really want is a poll so I can quickly see the numbers. What I'm trying to see is how many people are running 3 core machines and how many people have 6 core procs. Keep in mind I want to know actually cores, not the number of simultaneous threads you can run. Also, if you're using a multiprocessor machine please add up your cores. Also, if you have a triple core machine but it's not your primary I would appreciate it if you would post so in the thread.
 

A:How many cores power your primary machine?

Work related question or just curiosity?

I run 2 cores now in almost everything I physically use. I have a single core system that runs and does stuff for me nearly 24/7, but I almost never sit in front of it.

A:Acer Extensa 5235 problem booting

I had to look up BartPE to see what it was but I think it's unlikely to save the day in your situation.

Assuming that your priority is to get Windows 7 back I'd first check that you have the Microsoft authorisation code for your copy. If it was pre-installed on the laptop there will be a hidden restore partition and you could try holding down the Alt key while tapping F10 to access it. Failing that option I'd download a Windows 7 SP1 ISO, burn it to disc, reinstall the OS and hope that there are no serious driver problems. Both options mean that everything you have installed and saved will be lost unless you have already made backups.

I have checked all drivers and windows shows they are up to date. Both displays were fine as of about 1 AM this morning, and to my knowledge no updates or downloads were done during this time.

Any help would be appreciated; I work from home and having dual monitors is almost critical.
 

A:2nd display black screen

Try changing cables first, by some chance the cable has gone bad.

Sounds like it could be a lighting issue within the monitor. If it is a backlight issue, the monitor will still be displaying an image. You will not be able to see the image without some kind of lighting. If you can use a flashlight to expose the image, you would at least know it is a backlighting issue. I've been able to use this technique on phones as well as monitors.

I have been looking around and cant find a cut and dry answer to my problem.

What I'm looking to do I set up 6 monitors on 2 gtx 980's. My question is if its possible to have 3 monitors running in landscape as well as 3d and the other 3 as separate workspaces. Or can you only get 3 total monitors to work with nvidia 3d. And it gets more complicated when SLI comes into the picture since I would like to maximize my cards. But correct me if I'm wrong, SLI essentially turns my 2 cards into 1 not allowing me to utalize all the video ports on the 2nd card. Meaning I won't even be able to accommodate 6 monitors? I may just have to do without SLI.

So again. 3 monitors in surround 3d. 3 monitors not inside the 3d or surround environment. Off of 2 Gtx 980's. Possible? If not is there a way to accomplish this with other hardware.

Thanks for your time. SF

A:New Build no power-up: case's power supply or MB?

Well, I figured out the problem.
I am planning to re-do the older mini-itx system I have; it has gotten riddled with Trojan software for kids downloading games; it basically has been de-commissioned already.

So, I took the pico-psu power supply from that older computer, and hooked it up to the one I am making. Everything went perfectly.

So, I un-did that, removed the MB from case, disconnected the barrel-power connection from the case, unscrewed and removed the power supply that had been mounted in the case, put the pico-psu power supply back in place (I had to drill the hole for the barrel-connection out to be a little bigger since the pico-psu internal/external connection is threaded and held in place by nut with lock washer), and routed wires to be clear of cpu fan, screwed MB to stand-offs, and closed it all up.

now, everything is great. I like this linkworld case, but the power supply is worthless. I may try to get a few dollars back from the ebay vendor, to make me happy with a case that is less than what I should have gotten, but is working for me; I don't want to wait on returns, etc.

Hello...I will start from the begining .

I bought the Acer V5 and tried booting it up...it came with boot-up Linux which means nothing to me so I made a Windows 8 bootable USB and the problems started. First I could'n find the USB and after enabling the Legacy mode it finally found it and booted from it. Turned out the partitions are GPT and as I made the USB MBR it couldn't install so I canceled which I guess was my mistake but there was no other option. After that I created the bootable USB with GPT partition scheme and tried again. Unfortunately this time I got something called GNU GRUB....wth? I googled around and found the commands required for booting - root (hd1,0), then chainloader +1 and finally boot. Then I get the famous The Boot Configuration Data for your PC is missing or contains errors with Status: 0xc000000e. Of course tried that couple of more times but still to no avail. I cannot recover or repair as Windows was never really installed, so I don't know what to do....Hopefully someone here would be able to help. Thanks in advance guys.

I usually connect the vga cable from my monitor to the port on my gpu,but for some reason it doesn't display anything now.

I tried to locate the source of the problem by doing these

1) Connected the vga cable from my laptop to the monitor, and it displays the laptop's content just fine so the monitor/cable isn't the issue.

2)Connected the cable to the vga port on my samsung smart tv and to the slot on my gpu and my desktop boots and functions just fine.

3) I opened up my cpu cabinet and dusted the ram and the video card and put everything back in place but that didn't help either.

I don't have a DVI cable with me so I can't check if that works and I don't have another similar monitor either I can test it on other than my tv.

Video card: AMD HD6770

Monitor Samsung 23'S22B series

Is the port you're trying to get video out of active? It might be turned "off." Just a thought....

I had a completely new experience.

I installed a new R9 280 today.
I have a CORSAIR HX Series HX750 750W 80 PLUS GOLD PSU. ([email protected])
I was running an ATI 6870.

Previously I never heard the PSU. While checking out a game a fan ramped up and I thought it the
R9 280. I thought man that's loud. Through some experimentation I found the R9 280 fan noise was not the problem but the HX 750. I cannot tolerate too much noise from my computer so this PSU has to go.

I know the R9 280 draws more power then the 6870 so the PSU is doing it's job.

My question is: How many watt PSU would I need so it won't ramp up....or are there other considerations I need to focus on as well...besides the +12 rating and wattage.

Thanks for any help

Josh*^ - the lights could not possibly be pulling more that 10 watts, at an extreme. Probably they are actually pulling a level that you could not notice before-and-after if you used an actual measurement, such as with the Kill-A-Watt.

Same for fans, and most anything else you plug in or on except video cards.

Everyone: you will spend all kinds of money to have powerful components, and a suitable power supply - so go ahead and get an ACTUAL power draw measurement -

The kill-a-watt is simple to use and read, very simple. it costs $20 or $25.

You can use it on anything you plug into a 120 volt outlet. Vacuum cleaner, hair curler, radio, anything. It tells you exactly how much power is being used. Exactly.

For over a decade, these power calculators have been estimating power needs, and they have been over-estimating by 100% the entire time.

Greetings I ve moved to another country where electricity is not stable and goes high low or even disconnect power failure many times a day So i brought an old UPS i have discovery and connected it to the outlet and connected the PC and the LCD screen to it Sometimes when the electricity goes high down the UPS seems can t regulate fast enough or when the electricity disconnect the UPS can t change to battery mode fast enough so the PC restarts I though the problem is from the UPS so i bought failure during My despite restarts UPS PC power a new one iXA PRO which also has a built in AVR with wide input range of - Vac wide range of input frequency output short circuit protection overload protection and the transfer time My PC restarts during power failure despite UPS is ms I connected the PC and the LCD screen My PC restarts during power failure despite UPS to the new UPS and connected my modem and an external hard to the old one Surprisingly when the electricity went high low or when it disconnected the modem did not reset but my PC restarted which means that the old UPS is still working and the problem is from the PC itself I use My PC restarts during power failure despite UPS a very god power supply Blue Storm - wat so any idea what the problem could be Note When the electricity goes high low or disconnect the PC doesn t actually restart it just half turned off i mean i can still hear the fans rolling but there is nothing on the screen and i have to turn it off then on Note Sometimes when electricity goes high low or disconnect the PC keeps working normally Thanx in advance nbsp

A:My PC restarts during power failure despite UPS

My guess is your power supply in your PC uses active PFC (Power Factor Control) while your uninterruptible power supply is likely rated for a passive PFC.

My sister's 13" MBP (2011) died a few hours ago. According to what she told me, she was using it, and then, poof, black screen and no power. She doesn't have the cash at the moment to have it properly checked by a tech, so I did a basic troubleshoot in an attempt to narrow things down.

While the internals are a bit dirty, I didn't see any obvious signs of physical damage (it was relevant to check for this). Furthermore, the machine doesn't seem to respond to any power sources. I tried a couple different power cables and, while the little amber light on the magsafe (sp?) tab will come on briefly, the computer with neither power on nor display a charge on the built-in charge indicator. I will also note that the machine failed while disconnected from an outlet source with a full battery indicated.

My initial conclusions are a) the computer fried itself or b) the battery is toast. Any suggestions?

Hey guys, I'm pretty much a noob at this.
Long story short... My acer aspire 5552 will not stay on. When I turn it on I have to press on a certain area if not multiple areas. Before I had opened it and cleaned out the fan it use to overheat like crazy it used to hit about 90 degrees I'm wondering if that has ruined something?

Please help!
Thanks in advance
 

A:Acer Aspire 5552 won't stay on

First of all. Why do you have to hit certain area or for that matter. Multiple areas. It may still be running to hot. Or something was damage when you put in back togather. If it is running to hot . It may need new thermal pads.

When I power on my Toshiba equium a200-151, the screen lights up but no display at all - even though there is loading activity. I rigged up to my PC monitor and everything is fine - see bios and windows loading etc. Borrowed a spare compatible working screen but same problem. I'm not 100% sure if its the inverter or the ribbon connector - any ideas before I buy a new inverter? Thanks for looking.
 

A:Lcd lights at power on but no display

I would say that the video cable (ribbon cable) is bad based on what you have tried so far. This cable goes from the motherboard to the LCD display. Did you use the old inverter off the suspect Toshiba when you tried the compatible spare LCD panel?

Just ruled out malware in other section of this forum. Laptop's integrated keyboard suffers intermittent lock-ups for no apparent reason (sometimes works, sometimes doesn't, right now, doesn't). Touchpad seems deactivated (tried FN + F7 in case of accidental disable, but that's not the case), every option related to touchpad are grayed out in 'mouse' menu (config panel). Before malware check-up,tried system restore to last week, all problems were still there, so I reverted back. I have to use visual keyboard to type. Have to work with external mouse because touchpad doesn't work. Tried reinstalling touchpad drivers from Acer website, and didn't work. Computer worked perfect a few days ago.

Sounds like you may have some system files corrupt. This can occur after a lot of spyware. Some times just removing it dose not correct what it has already messed up. Your best maybe to back up your personal stuff. Then do a factory reinstall.

Hi there. Since I bought my new mouse and illuminated keyboard, when I use the PC a lot, they have spontaneously been stoping for a period of time and then they work fine. I didn't have this problem before because I had a ps2 keyboard. Now I have USB mouse and keyboard and this happens. I do believe there is a problem with the power management. A friend of mine has the same motherboard and he incurs the same problem. I have a Gigabyte GA-B75M-D3V and here is a printscreen of my bios with the power management tab.
What settings should I change?

Hi,

I think you'd be able to adjust that power management settings in Windows under

Control Panel>Power Options>Edit Plan Settings>Change Advanced Power Settings>USB Settings
Or in Device Manager>USB Root Hub Properties>Power Management Tab

A:Is my mob compatible with new Video Card & have enough power to run it

No one can say if it will run with no issues, just because there could be any number of complications that could pop up. If you asking will it work with your current system, then yes it will run on your current system with the PSU. I would advise that you uninstall the video drivers (and software) for the current card, changing out to the new card. This will create less of a head ache for you in the end.
I would also suggest trying to find another 2GB ram stick because your motherboard is a Dual Channel motherboard and the computer will run better if you have 4 sticks of ram instead of 3. Its not going to hurt your computer by having 3 sticks of ram versus 4, but you will get better overall performance.

So newegg is offering the Acer 29" B6 B296CLbmlidprz IPS monitor for about 350. Seems like a pretty good deal but I can't find many reviews on it.

I want to game with it as well as do some 3d modeling and photoshop work. So I need reasonable response time for gaming. I was also looking at the HP ZR2440w and was gonna get that until I saw this deal on newegg for a larger monitor. 24" models are fine but if there are good deals on some 27" inch ones then I would be interested in those as well.

The results are in the attached file It shows LL which means to low to register voltage for the - V line I honestly don t know if I even have that line so I don t know if that s bad I attached the label on my power supply too Would Power button not working... mobo issue? no voltage cause a computer to completely not respond Because the fans DO start up when the power supply tester is plugged in I don t think the switch is the problem because I tried to short the power switch jumpers with a paper clip and nothing happened I also took the CMOS battery out for a while and then tried it again and that didn t work Any ideas on whether I need a mobo or a power supply I don t have an extra PSU around to test with but I may try to find one before ordering a new mobo thanks in advance -mike nbsp

A:Power button not working... mobo issue?

Not the switch. Could be the motherboard or PSU, but I don't have any good insight.

I would unplug the PSU and flip the 120/240V switch to 240V, then flip it back before plugging it in. To me, this doesn't make any logical sense, but over about 16 years of playing with PCs I have seen it work twice.

Hi,

my acer laptop 7520 shuts itself down after booting for few seconds.
It has Vista but dont think its a software / virus issue. As I got into BIOS / booting menu, it did not stay there. it shuts itself down.

I removed CD rom from laptop but had same result. It has two 1GB rams, I removed them one at a time but had same result. I then removed Harddisk and tried to make it boot from USB, but had same result. It was shutting down after 10 - 30 seconds. I see the Fan running when ever I start the laptop. Fan is very clean. no dust, dont think its a heating problem then.

please can some one advise what could be issue.
thanks.

I ran it on full battery but had same result. Then I removed battery and connected the power cable into laptop, same result. it shuts down after few seconds.

Sounds as though its over heating. You might try taking a can of air and blowing the vents out. If this has not helped. You may need to take it to a repair shop. and have the thermal pads replaced.

My brother in law has a got himself a free computer to which I am going to donate my old Sapphire X1950GT graphics card. The problem is, is that I can't easily wire it in to the computer as it has a crappy generic PSU with only one Molex and several Sata power plugs.
What I do have, without slicing and dicing and getting out the soldering iron, is the adaptor cable below. What I don't know is whether this has a sufficient amount of wires I.e. 0V and 12V to provide power to my G/Card.
Any ideas?

Tom.


 

A:Wiring a graphics card to a generic PSU - sufficient power wires on plug?

System power consumption with a Sapphire X1950 GT is less than 250W. I think you will be fine with the splitter mentioned above. You probably don't need much extra power to run the card. I assume there is at least a 300W PSU or greater in the system.

Hey guys, I'm planning to get a laptop for general stuff and gaming. It's important to me that I can play PC games that aren't too intensive graphics wise. I need a laptop that can run games like Skyrim, TF2 and some MMOs at preferably medium to high settings (but I could go for med to low). The laptop I've found is here:
ACER V5-552 15.6" Laptop
Processor: AMD A10-5757M (2.5GHz, 3.5 GHz with Turboboost, 4MB L2 cache)
Storage: I TB HDD (5400 rpm)
6 GB RAM (DDR3) Up to 12 GB installable RAM
Graphics Card: Integrated Radeon HD 8650G
Resolution: 1366x768
OS: Windows 8(.1)
Is this going to work well with fairly easy games or could I go even more intensive for games like Crysis 3 and BF4?
Thanks for your help,
Joe
 

A:Acer V5-552 Laptop For Gaming

That processor is OK for gaming but the built in GPU is a little low if your expecting high settings even at 720p (With a decent framerate of course). On a game like Crysis 3 Which is so heavy on GPU's, you will likely only get low on that. As for BF4, I can say Medium 30+ FPS at that resolution. If you want a gaming grade laptop, your going to have to jump up a few notches for performance.
This is a medium-low end gaming laptop designed more for people playing not as intensive games as your listing. If you have a budget, could you list it and we will make some alternative solutions. Im assuming around $550 since newegg lists that laptop for that price, but with only 384 stream processors your not going to get far with that even at 720p except on the low settings. BF3 for instance on the 7660D (Which is just the 8650D essentially) runs at 58FPS average on low settings on a 720p monitor.

Hello all I made a post regarding the performance failing of one of my supply power affect hard performance? drive/computer Faulty hard drives The conclusion we came to has unfortunately not resolved my problem and I am beginning to think my Power Supply may be the culprit Faulty power supply affect hard drive/computer performance? ------------------------------------------------------------------------------------------------------ Before I go into details here is my current Hardware Q GHZ GIGABYTE EP -DS R GB PC mhz x gb x gb Nvidia GTX mb requires x pin power adapters Asus Xonar soundcard requires floppy power adapters Windows x Jeantech W PSU modular PSU PCI-E nodes and nodes for other devices gb HDD operating system tb HDD data tb HDD data tb HDD data - added recently ------------------------------------------------------------------------------------------------------ My original problem in brief Upon accessing certain files in one of my TB drives I hear a distictive quot click lockup halt quot sound and then the entire system crashes first the drive will become inaccessible then windows explorer will crash followed by the mouse and eventually a BSOD after a minute ------------------------------------------------------------------------------------------------------ I bought a new TB a month ago to replace what then I thought was a failing TB drive Since the problems have become quot random quot and happen across all four drives tb tb gb tb I am now considering my PSU the culprit Jeantech Absolute w It seems logical to me Sometimes while performing tasks which put stress on several HDD s at the same time my computer is quot choking quot running as fast smooth as it should but with sudden freezes with those HDD quot click - stop - restart quot sounds Booting into windows is failing from time to time freezes on the quot starting windows quot screen or DISK BOOT FAILURE Insert system disk The PSU is modular - could certain quot plugs quot in my PSU are faulty I haven t tested this extensively but in some cases when the computer is not starting up at all using different power ribbon cable combinations seems to help Also I had to remove my DVD drive completely when I first installed the new TB I bought and I don t think my computer will start at all with it plugged in anymore so my PSU MUST be having a hard time coping with all the components If it is of any relevance I use an Nvidia GTX which requires x PCI-E pin power connections hard drives power is supplied via THREE modular ribbon power cables - two HDD s share power from the same ribbon cable lastly worth noting I use an asus Xonar sound card requires floppy power connector several symptoms suggest the PSU any thoughts nbsp

A:Faulty power supply affect hard drive/computer performance?

a 1000Watt shouldn't have any problem coping with the components that you have, i would recommend that u borrow a power supply from a friend and try it out on your computer, maybe the power supply is old and is not supplying proper voltages on all the rails....

Hi can anyone help please, I just received my new Plait GTX Nvidia 770 Jetstream card and noticed it came with an 8pin and 6pin power requirement. They provided a 6pin to 8 pin adapter and I have a Corsair 650 TX PSU with 2 6pin power lines problem is the 6 to 8 pin adapter looks like it need both 6pin lines from the PSU to provide the necessary voltage/amps and that still seems to leave me short the other 6 pin port on the GFX card. Do I need to plug both 6 pin attachments in to the adapter or will one suffice?
 

A:GTX 770 Power Requirments

My bad, silly fool that I am I failed to realize both 6pin PSU power lines also have additionally the other 2pin lines required to make up the 8pin connection right along side. Thought I may need a newer PSU there! LoL

Hi,
I gave my external hard drive to a friend but his laptop didn't recognize it. after getting it back, I connected it to my laptop but it didn't show up in disk management at all. the drive is receiving power since the light is on. I felt the drive upon connecting to laptop and noticed it tries multiple times to rotate the magnetic disk but in the end it come to a stop and nothing after that. I think my friend's laptop somehow damaged my drive since I'm sure it's a hardware problem.
So, I was wondering maybe any of you guys have an idea how to fix it if possible otherwise, I'd like to know if I can recover the data without spending for the experts?
Thanks
 

A:WD external drive receiving power but not working

Hey armmzd. Sure sounds like a drive gone bad, and assuming you know it was good when you gave it to him,maybe it was dropped,etc. All I can suggest is going to the drive manufacturer's site and see if they have a drive diagnostic tool you can try.

Hi guys I ve spent today building a pc for myself However on pressing the on button there s no reaction at all My machine specs are M B - Gigabyte GA- A-UD Processor - AMD RAM - Corsair Gb DDR Case - Zalman Z Graphics card - Gigabyte HD PSU - Corsair CX M W Wi-fi card also installed but can t remember the name and seem to have temporarily lost the box in a pile of packaging So far I ve checked the CPU and motherboard power sockets the wall plug sockets and the power cord to my PSU I ve also checked the connections between my case and the motherboard and these all appear to be correct on power build PC doesn't As part of this final point I switched the power on LED with the power button they both originate from the same location so thought they may be mixed up Anyhows I got a solid LED which suggests to me that a there s power running through the switch circuit and b the pc isn t booting when told to as a PC build doesn't power on solid LED would indicate PC build doesn't power on circuit completion which would be the equivalent of holding in the on button If anybody could shed any light on where to go next I d be eternally grateful currently searching the house for a paperclip to test the PSU nbsp

A:PC build doesn't power on

Does the CPU and case fans move at all, when pressing the power button?

Hello! I'm having no luck with previous threads regarding this same question.

For starters, I just bought two new items for my computer so it's not entirely new, but quite the upgrade

Previous Specs:
PSU: 500w
CPU: AMD Phenom II x4 965
GPU: nVidia GeForce 660
MOBO: Biostar A880GZ
RAM: 8GB

New Specs
PSU: 500w
CPU: Intel Core i7-4820K
GPU: nVidia GeForce 660
MOBO: BIOSTAR TPOWER X79
RAM: 8GB

I boot it up and hear no beeping sounds all fans are running well. I believe I have everything in place. I can provide pictures if needed.

Thanks in advance!

Maybe there are some extra plugs I need in the PSU that my current one isn't offering?
 

A:PC turns on; Monitor won't Display

Recheck all your connections. Plus make sure your video card and memory are seated. The PSU should be fine.

Hi everyone,

I have the Acer GN245HQ 3D monitor and I need your help to set the parameters of this screen for that I can have a good calibration of colors, and the best reactivity in game, for exemple what's the right value that I must set in the OSD, now I have the default value OSD=10.
Im using the GTX 680 graphic card.
Plz help me.

Thank you,
 

A:Acer GN245HQ Settings

Colours are subjective to each display, so must be calibrated separately. Google around for guides.
