Monitor and/or GPU Problem

[Mitchrigg]

Hello,
Every now and then when i'm gaming or just watching videos on my pc the monitor goes black for a second then returns back to normal, but does it at random over time.
I've tried taking out the GPU and putting it back in. That didn't help. (I have two monitors)

I thought the GPU might be under volting but not 100% sure. All temps are good so i don't have a clue whats wrong if the cards just faulty or my monitor. I haven't had this monitor for long (about 6 months)

My PC specs:
Intel Core i5 4440 Quad 3.1GHz CPU
Nvidia GTX 760 with acx cooler
1 stick 8GB RAM
Windows 8 64bit
600 watt PSU

Try another graphics card. Try your graphics card in another pc.

Check your DUMP file - c:\DUMP

Check temps - cpu and gpu

I think i have seemed to found the problem. For the gtx 760 it requires a 12v rail with a rating of 30 amps, my psu does not so hopefully if i get a new one it should be fixed

I would probably go with the thermaltake toughpower 750 watt power supply.

Can't see the first one. But the Toughpower is on second tier so OK!

I think the old one is a Tier 3 psu "not ideal for serious overclocking"
