So I was not sure where to post this thread as I cannot identify what is causing my system to crash. But first, my specs:
MB: 990fxa-ud3 AM3+
CPU: AMD FX 8350 (not OC'ing anything at this point)
RAM: G. Skill 2x8GB DDR3
GPU: NVIDIA GTX 760
OS: Windows 7 64-bit Home
PSU: Thermaltake TR2 600W
Okay so now the issue. My computer is crashing or powering off instantaneously at certain times when I am using it. It reliably starts up, and I have never had a crash during boot or BIOS. After a crash, I cannot power on my computer. If I wait for hours, I still cannot power on the computer. The only way I can restart is to unplug the power cord from the wall and/or the PSU multiple times until I can power on.
When this crash occurs, my computer is completely powering off in an instant. I feel I can hear clicking noises (maybe from the PSU?), and maybe sometimes when the crashes occur. So what is strange about this is that the crashes were predictable. If I used opera internet browser, it would crash almost immediately, while windows internet explorer was mostly okay (still occasional seemingly random crashes). So what is even weired is that Steam software tended to crash the computer, though I could play Rome Total War 2 through Steam (which is very computer intensive) with almost no crashing (I cannot remember it crashing during play). However when I tried to play a different game, XCOM Enemy Unknown, it would crash during the loading screen right when the game was showing the Firaxis logo. Anyway, I formatted the HDD, installed a fresh Windows OS, and ran several updates and downloads last night, and the computer stayed on for 8-9 hours without crashing. Today I installed drivers and installed steam and everything seemed to be working great. I loaded XCOM without problem and played for an hour or two and then the crash occurred again. I restarted and tried loading the game, and now it is crashing on that same time as before. I am running a test for defective memory on each RAM stick now, but I do not think this is the problem. Im guessing its the new PSU I bought but does anyone know of a way to test this? I have a 500W PSU on this computer that I could throw into my old one if there isnt a better way.
Thanks in advance
