Built my own PC - crashes when playing high def video or when quitting games.

That's the PC i built earlier this year, and ever since I got it, it has been crashing pretty consistently whenever I play a high def (blu ray quality, etc) movie, and maybe one in ten times when i quit a game to desktop. This has happened on multiple games including: league of legends, portal 2, starcraft 2, witcher 2.

When the crash happens, the screen will freak out, audio will continue for a few seconds, then it crashes and the only way to fix it is by hard resetting the computer. I can't tell if it's my graphics card, my hard drive, or my motherboard. I've never built my own PC before this, so I am kind of new to the whole process and new to diagnosing it.

Yes, I have updates all drivers for my graphics card, motherboard, and hard drive. I am running windows 7 ultimate (legal, not pirated), and all of my games are legal, non-pirated copies as well.

If you need any more details let me know.

[](/solved) It was my graphics card and the latest drivers have since fixed the issue.
