My PC which I built 7 months ago has started to suddenly shutdown with no erros or BSODs. I recenty OC'd my processor (havent touched the gfx card) from 3.4GHz to 4.2Ghz and everything went well with core temps staying around 48-53 degrees by stress testing through prime95 as well as playing a few videogames.
The first shutdown happened a few days ago when I was playing Assassins creed 4 for a few hours. I thought the overclocking could be the problem so I went into the BIOS and restored all settings to default but it shutdown again after an hour while restarting a paused video on firefox.
After troubleshooting a bit more. I've discovered it will always shutdown if I play a graphic intensive game(note: graphics card temp at 75c when playing), alt tabbing and then going back into the game. I also tried playing battlefield which was choppy and stuttered even on low settings and saints row 4 which shutdown in the main menu. The only game that seemed to work properly was starcraft 2. On every occasion I couldnt seem to turn it back on again unless I waited for about 10 mins and unplugged it from the mains.
I've read a lot of similar threads but I'm still not quiet sure what the problem is whether its overheating graphics card, a dieing PSU or motherboard.
Any help will be greatly appreciated. Thanks
