wierd computer problem

[Lord Revan]

I had wierd issue with my new PC, that it sometimes crashed when I tried watching Youtude or similar vids (first at random but then pretty much everytime until now, it won't even boot up properly (I'm using my old PC now))., so my question is that does anyone know what could be the cause of this problem (I had Windows 7 on the faulty PC)?

Maybe it´s overheating. I had that problem on a Laptop PC which was very dusty inside. As soon as the CPU or GPU had to do a bit of work the computers heat would rise over 100C and autoturnoff.

If it started with youtube and ended up being the full system it could be the graphics card. Can you explain how it boots up now? Does it get to the BIOS startup image, does Windows start to load?

it's gives the BIOS image then goes to inbuilt repair utility for the Windows and when I try to run that it says it cannot fully repair windows (and thus cannot start it).

then why did WoW or SWTOR not cause an auto shutdown but Youtube and Blip did.

I think the "refusing to boot up" problem might be a simple case of something getting corrupted by one hard reboot too many, and a clean reinstall of Windows should fix it. Crashing from playing streaming video I'm not sure about, though, but it sounds GPU-related; try the manufacturer's tech support forums and see if anyone else has had the same problem, if you're lucky it might just be buggy drivers.

If windows boots up to repair I'd agree that a clean install is in order. If you need to back up files still I'd do a live boot to a linux distro like Ubuntu or Mint and copy the files onto another hard drive. The flash/video problem could have been a driver issue or an actual issue with the graphics card itself, but seems disconnected from causing windows not to boot.

Ditto on the live Linux distro, and make sure you open the Disk Utility while you're in there and check the hard drive, it may have bad sectors. I just had that happen today, in fact. I was replacing a customer's failed hard drive and reinstalling Windows XP. I got Windows installed and activated, and was just finishing installing drivers. When the computer automatically rebooted after installing the video drivers, I got a UNREADABLE_BOOT_VOLUME bluescreen. Loaded up our Ubuntu live USB, checked it in Disk Utility, and sure enough, it had five bad sectors. This was a brand-new drive, mind you. I had to grab another drive and reinstall everything all over again.

You may have some luck with the Windows Recovery Command Prompt, though, using bootrec /fixboot and /fixmbr.

I took my PC to maintenance and it seems what ever the problem is, it's probably not software issues. It's under warranty and the store I bought it from said that they had sent it to a licenced maintence/repair company which means it's something they couldn't fix in-house.

Which also means I'm stuck with this old broken PC in until the new one is fixed.
