Hi, Recently whilst I have been gaming, the games have started to either freeze or shutdown (with no warning, just goes from game to desktop with no explanation) completely. The main culprits for this are SW:ToR and CoH:ToV, although it happens on Crysis 2 as well. At first, I thought it was my GPU getting too hot so I checked Catalyst Control Center and turned the fan speed up to 45%, but the problem is still there. I installed HWMonitor and even though I play the above mentioned games on either High or Ultra my CPU and GPU temp hardly go above 60 degrees C. Could it be that my PSU is starting to die?? When I open the case it smells as if something is burning or has been burning, but not overpowering. Its also worth mentioning that the shutdown sometimes happens when I watch Blu-ray movies, but not very often. In case you need to know, I have the following set up: Intel i5-750 (no-overclock) Gigabyte H55M-UD2H 8 GB Crucial Ballistix RAM Sapphire Radeon HD 5850 Scythe Shuriken Cooler Be Quiet 600W PSU Any advice with the above will be greatly appreciated.
