Random restarts and freezing

[Rayvin387]

Hi Guys, need a bit of help

I built a gaming rig for my girl, only recently ive started seeing Random restarts and freezing with my own eyes.

she has mentioned that the pc did that once in a while, i never had any problems even under stess testing or gaming.

 

No Blue Screens,

windows error recovery - windows did not shut down successfully

 

PC Specs: (nothings overclocked)

OS: Win 7 64bit

CPU: AMD FX 8320 3.5ghz 

CPU Cooler: Xigmatek Dark Knight II Night Hawk Edition

Motherboard: ASRock 990FX Extreme4 Socket AM3+

RAM: 8GB Corsair Vengeance DDR3 @ 1600mhz CL9

GPU: XFX Core Edition Radeon HD 7870 2GB GDDR5

PSU: Corsair CX750M 750 Watt Modular PSU

SSD: 120GB OCZ (with the OS)

HDD: 250GB something laying around (Steam games)

 

 

I've run mem tests - memory came back fine

changed outlets and added a surge protector - problems persisted

swapped out PSU for another 750watt - valley benchmark stopped responding (first time seeing that)

 

so far i cant control when the problems happen, seems random.

i have my gaming pc and other parts laying around. (if needed)

 

im just a little stuck right now, any help would be appreciated

I had a similar issue a while back...

When I did my new build, I installed 4 sticks of ram (32gig) 2 pairs....

It started to do exactly as you said so I started troubleshooting and went straight to the ram

 

I noticed removing some sticks fixed the problem while others caused the problem, so I fiddled about till I found the bad stick and removed it, along with its matching pair, so I now run 16gig

 

Sometimes its easier to diagnose the problem physically, rather than using software testing

Switch out the power supply. There has been a lot of horror stories with Corsair CX series PSUs.

I thought your suggestion was a long shot, pulled out the ram and tested each stick and socket.

 

Turned out one of the sticks went bad.

 

Thank you!

 

P.S. this is the 2nd time corsair vengeance DDR3 has gone bad on me...
