I recently built a gaming pc in September and have had no problems up until about 3 days ago.
While playing Rome Total War Barbarian Invasion I experienced bad FPS most likely caused by the amount of units on screen and about halfway through a battle my screen froze and I heard a loud noise, my pc does not recover so i have to restart it. This has happened ever since if I try to play any game after about 20 minutes. I assume its my GPU and its temperature is currently at 34 degrees (just after crashing)
Phenom II x4 965
600w Corsair PSU
Can I just add that there is no change in sound from the actual Hardware itself
