Before I begin, I will lay out my PC specs:
Mobo: Asus M5A97 LE R2.0
CPU: AMD FX 8370 Black Edition (overclocked via ASUS Bios overclock function, no manual changes on voltages)
GPU: Geforce GTX 550 ti
PSU: Corsair TX 650 watt
RAM: 2 4gb sticks Corsair Vengeance DD3 1600
Enermax CPU cooler
Artic MX-2 paste applied to CPU.
*All temps monitored by HWInfo. CPU core kept within 10 - 40 degrees tops with CPU intensive gaming. GPU kept below 70.
While I was playing Starcraft 2, my PC suddenly froze (with current image on screen) (no BSOD) and ctrl alt del did not work, so I had to manually shut off my PC. After several attempts at powering back on, nothing showed up on my monitor (as if it could not get a signal) but my computer appeared to be running normally "behind the scenes". At this point I assumed my video card might have died. I tried installing a new EVGA GT 720 and had the same symptoms. Also, my PSU fan, GPU fan, CPU fan, and case fans all work when powering system on. Note: The GT 720 differed from my original card in that it is only about half the size of the slot (I was told this did not matter). I also tried removing my RAM and installing a new 8 gb Hyper Fury stick. This also did not work. I have also tried 2 difference monitors including 1 via VGA and my TV via HDMI -- neither of these loaded a picture either. I am now thinking my CPU and/or mobo died but I don't have any other systems to test them on. I would rather not pay someone to diagnose it when it's cheaper to just purchase new parts. Where should I go from here? Should I try installing a new CPU and then if that doesn't work try a new mobo? Any advice is greatly appreciated...
Thanks a lot,
