Windows 7: Win 7 crashes alot

hey guys, im very new to this forum, and ill admit im more of a meat head than a pc geek, haha so it may be hard for me to do this...anyways i have a decent pc, put together for me like 2 years ago by a friend, to be ready to run the game Crysis, and Call Of Duty and at the time it was fantastic to run these games, still works well now but i have some issue with it crashing, alot ever since i upgraded to Windows 7 from vista. It seems to crash alot more during game play (modern warefare 2) and still crashes when im just on the internet and winamp is playin tunes.... is there anyone who can help me? any help would be greatly appreciated!

Hello there MackTruck49,

Is your DVD of Windows 7 a Retail Version or an Upgrade Version?

To get the best out of Windows 7, we recommend you do a clean install.

This tutorial should get you through.

Good Luck.

Do yo know what sort of temps you are running. Have you checked the cooler for cleanliness? Heat will cause your problem too. PSU problems can also cause random crashes. Before you go for the clean install you might just get away with an easier fix.
