Random restarts

[JCMZD]

I am having random restarts when playing games with no explanation. Recently, I went into the bios after the latest restart and I saw that some cpu voltage was on red. what could be causing the problem? thanks in advance

 

System Specs:

i5 2500k

8 GB G skill sniper

Asus p8p67 WS Revolution 

Evga gtx660ti ftw signature 2

Corsair HX850W

250G samsung evo pro

1 TB WD caviar Black

Could be a form of crashing caused by system instability, I can't read the numbers so what is your cpu voltage set to and is it overclocked. As for what may be causing the problem I'd say power instability (either from the cpu degrading overtime, unstable settings on the cpu or psu power spikes) is a fair possibility but am not 100% on that, it's just a hunch.

So your psu is outputting only 2.9 on the 3.3v line? Something sketchy going on. I would try a different psu to see if the problem goes away. Also check if the mobo 24pin connector is loose.

was overclocked to 4.5 @ 1.2 volts then i brought the clock down and still doing it. I reset the cmos and seems fine for now

usually does this when its dusty I clean it and works just fine. This time I cleaned it and kept doing it. if its the psu I may need to source one because I only have this one.
