I have recently acquired a secondhand custom built PC. I ran Fire Strike because I wanted to test it out.. It was running fine for a couple minutes, but then the screen started glitching out and the computer reset itself. I've noticed that occasionally the screen will also randomly blank out for a second or two and then come back on. I'm not sure if this was happening before the Fire Strike crash, but I didn't notice it until afterward.
The PC has two Gigabyte GTX 780 TI's in SLI, and has a Coolermaster V700 80+ Gold 700 watt psu. From what I've been able gather online, this isn't enough power for SLI... And I was thinking that's why Fire Strike glitched out and crashed. As for the screen randomly blanking out at times, I first noticed it in SLI, so I thought it may also be something to do with the psu, but I've recently noticed it does it with SLI turned off too.
I'm really not sure where to go from here... Do I need someone to look at it, or can I run some sort of diagnostics or such?
