Why does my computer keep crashing?

[Hyper-Threaded]

Once in awile I play games and they wil freeze up, I haft to open task manager, screens all messed up, and I haft to do a hard shutdown and restart. Ive been playing tf2 and its getting worse. Now every 15min. What Event viewer logs should I post? So you guys know what could be the problem? Thanks.

Sure your overclock is stable? Have you checked temps? RaidMax power supplies are pretty much junk.

Ill bumb it down to the stock 3.3. Temps are fine, cpu never goes above 60c. Even running prime95 all night.

Thanks.

Yes definitely lower the overclock and stress-test it for several hours with Prime95 before you start gaming again. Also make sure your temps aren't too high. If you haven't in a while it may be worth dusting your PC down a bit.

Ok its running stock 3.3ghz on 3 cores (I reset bios to factory defaults). (Even at 3.8ghz 4 cores) Its very random, sometimes it wont crash all day, and sometimes every half hour. Its Ideling at 24c, and after it crashes the temps are at 40c. Then it quickly drops back down to 24. And I already checked no dust.

And sometimes when it crashes I can open task manager and end it and be fine. Its very random.
