when i have been playin pr lately at random times my computer will lock up and a repeating sound will run. This just started a couple of days ago and hadnt occured b4. Im runnin a 7600gt, pentium d 2.4ghz dual core, 2gb ram, intel processors unsure of wat model. I actually switched this card from another computer in which i put a 275gtx. The game used to lock up in my other pc when i had the 7600 gt in it so maybe its a issue with the card :S.

Any help will be appreciated
