I have this problem as well... I recently bought a brand new computer specifically to play this game and a few others on at least high settings. And I seem to run into the same problem TehBrandon is having. I play on fullscreen for about 20-30 minutes sometimes longer depending whether my system has just been turned on or has been running for a while. And after a certain amount of time the game will freeze and sound will continue playing in the back for a few seconds. Now during this happening I cannot press Ctrl+Alt+Del or anything and doing so usually makes the computer freeze completely. So I am then forced to hard reset my computer. The only fix I have found for this problem is playing the game in "Windowed mode" which is not a big problem but would be nice if I can play in fullscreen. And I know it is not a heating problem of my computer or anything as I specifically bought a Corsair H100 water CPU cooler for this type of thing. The rest of my specifications are. CPU: AMD FX-6100 (Stock clock & H100 CPU cooler) Motherboard: Gigabyte GA-970A-UD3 Graphics: AMD Radeon HD 7770 XFX (2 in CrossFireX) PSU: 750W Non-modular (unknown brand) RAM: 12GB Corsair vengance 1600MHz Please it would be much appreciated if I can get any help for this situation. I think my PC is more than capable of handling this game as I play BF3 on Ultra settings without any problem for hours and do not suffer the same issue.
