Desktop shuts down midway through start-up process

Hi!

Last night my desktop crashed randomly, like there'd been a power failure. I tried to turn it back on several times, each time it would get partially through the booting process before powering down. Once, it made it to a 'system repair' or 'startup repair' process (can't quite remember which), however it commonly makes it to the 'your computer shut down unexpectedly screen' or the Windows icon screen.

I'm running Windows 7, with a nVidia 480 GTX, 4GB of RAM, an i5-2500K. I've had a look on Google for similar situations, and while it seems pretty common, there's not a large deal of information on how to actually go about working out what is wrong.

Thanks guys.

I had this happen to me

and it was caused by a fan failure. Once I replaced the fan, it started normally with no additional problems.

Tried several things

Tried switching sockets on the power point- no luck. Also made sure it wasn't an overheating issue- the fans are working. It's pretty dusty on the inside though, will give it a clean and report back. Is there anything else I can try while I'm at it?

Check *all* fans

In reply to: Tried several things

Al fans means the PSU one too. As you already found out, clean out the dust bunnies and use a can of air to do so. brush-off any other build-up, before you even try to power-ON again. Since, you already experienced repeated shutdowns, it may have now some s/w corruption provided it doesn't shutdown again. This will be a 2ndary problem to correct if that occurs. Don't rush this, clean and verify, etc., then try power again. If the problem persists, you have a bad PSU as well, the real crux of your problems, buy similar or better, NOT cheaper.

Had similar happen very recently

In reply to: Desktop shuts down midway through start-up process

The PC began acting strangely...not responding messages, etc. Eventually I had to do a hard shutdown as it wouldn't do a restart in the normal way. I was faced with the usual "Windows didn't shutdown properly" message. I tried safe mode and it just rebooted and went to the startup repair screen. That would fail to complete. I tried using the original Win7 DVD to do a repair installation and it would freeze. I tested RAM using memtest86 and it passed. I decided to make an image of the drive and Acronis gave an error about some unreadable sector. I had it ignore the error and complete the image. This was a WD drive so I did the WD diagnostics on the drive using another machine. Low and behold, my suspicions were correct. The drive had passed the SMART test but failed the media test. I had the utility do a repair which succeeded. All this means is that bad sectors are remapped to spares. I'd had WD diagnostics write 0s to all locations so my installation was gone. I was able to restore a previous image I'd made to a spare hard drive, pull the most current data from the last Acronis image and be on my way until I can buy a new HD.

I'd try to do a test on your old drive using the manufacturer's utility if you can. Don't mess with the drive until you do this. If it turns out the drive has failed, you may be as lucky as I was. The lesson is backup, backup and backup. Good luck.
