Windows 7 Going Crazy! NEED HELP!

[SMASH1337]

Ok so I've been running Windows 7 for about a month... maybe... idk I forgot how long but it has been great and I love all the new features (I got it through my college).

Lately though, it's going absolutely crazy. Here is a list of symptoms, I can't make heads or tails of it at all.

• ALL browsers crashing at random times
• iTunes will play no more than 4 seconds into each song before going silent
• Left 4 Dead is crashing and is giving me this error:
• Problem signature:

That's about all I can think of right now but it's really aggravating. Any help would be really appreciated.

Make sure your audio driver is up to date and there are no problems with it.
