I have no idea why my computer keep shutting down.

I'm using windows 7 64 bit edition. I'm having this problem for more than a week.

Especially my computer shutting down after 10 minutes when watching videos in vlc player.

My memory dump file also not created at all. I enabled small memory dump(256 kb) in this location %SystemRoot%\Minidump. But memory dump file not created so far.

Can anyone give me some solution to create memory dump file?

Thanks

Just a guess, but it sounds as if it could be a problem of over-heating. –  Xavierjazz Feb 19 '12 at 20:08

Since you don't get anything written to the disk, I would guess it's related to that. I myself experienced similar crashes on S2k8R2 recently, where the computer would stop doing anything for a minute or so before halting, particularly during heavy disk throughput like streaming a video. The problem in that case turned out to be a damaged SATA cable, but I guess a damaged disk or SATA controller are equally possible.

Try to check what the latest entry in the system log (or system event log? I'm not currently on a windows system, can't check.) before the reboot is, if there is nothing it's probably a similar problem. You could also disable automatic restart, so you might get a bluescreen explaining what caused the shutdown.

Finally, to make sure it is a disk related problem, you could try stress-testing the drive. I'm sure there are a lot of windows based benchmark tools for this, but I usually just boot a linux live disk and dd if=/dev/sda of=/dev/null bs=1M and watch the system log for errors. If this provokes errors or hanging, you can be quite sure the problem is related to your disk.
