Well I've had this issue for awhile now. It seems like every Battlefield game and Medal of Honor MP crashes on me. The screen freezes and theres a constant noise, it sounds like a buzzing noise or when an amp was just plugged in. At first I thought it was just because I had an overclock so i reset all of my overclocks and that didn't help at all. It doesn't happen right away, it happens about 15 minutes in. I run an i5-760 and dual sli GTX 470's. Even when I only had 1 470 i still had this issue but never thought much of it. I can run games like Crysis 2, Just Cause 2, Splinter Cell Conviction, F.E.A.R. 2, Bioshock, Portal 2, TF2, etc. without an issue. It just seems to be the battlefield series and what runs on the Frostbite engine. If anyone has experienced this and knows what the issue is and/or may know how to fix it I would appreciate your help.
