Ever since building my new PC last Wednesday, I have a rather peculiar Problem.
Whenever I start a Benchmark or a Game, my PC instantly crashes similar to the way it does when you turn off the PSU.
Sometimes Furmark, OCCT PSU Test and Unigine Valley will run for either a few Seconds or indefinitely.
However all other Programs I tried, like OCCT GPU Test, AIDA64 and any Game instantly crashes the PC.
All my drivers as well as BIOS are updated, Memtest86+ reports no errors and any CPU Stress Test runs for 6 Hours+.
If Furmark doesnt crash instantly the GPU Temperature goes up to 78-80° Celsius at 95-100% TDP. As mentioned earlier if the PC doesnt instantly crash the current Benchmark runs stable for 4+ Hours at Full Load.
After Crashing, Event ID 41 "Kernel Power Loss" is noted in the Event log.
My Specs are as follows:
CPU: Intel 4670K
GPU: EVGA 760 SC ACX
Mainboard: MSI Z87-GD65
PSU: Antec High Current Pro 750W
RAM: G.SKILL 2133MHz RipjawsX 8GB
If anyone is interested in helping me I would be glad to provide any additional Information you may need.
