Green Pixels on screen.

Hi, I have a GTX 660 Overclocked to 1098Mhz and I began to notice green pixels on the screen. I restart my computer and the pixels are gone. I've read online it's that a GPU is overheating, GPU is dying, or an underpowered PSU. I have 650W PSU and the tempatures for gaming is 70C and when web surfing 40C. Should I still be concerned?

What PSU model?

It's most likely that there's insufficient voltage on the GPU for your OC.

Like I said it's fixed when I rebooted but I'm worried if it will break in the future. My power supply model ps-cm-650w-24pin-v2 And my voltage in MSI Afterburner is set to default. Should I crank it up or should I just let the pixels slide since I don't encounter them?

Btw I accidentally hit the wrong button so I chose you as best solution lol.

Fixed.

I'd give it a few more millivolts - it's not good to run right on the edge.

I'd think about replacing that PSU at some point, though. Chiefmax isn't known for high quality.

How many? 5? 20? I don't want to screw up my system.

About 20 should be fine.

So, what would increasing the core voltage do exactly? And will it fry my CPU/GPU? (I'll just send you what my MSI Afterburner looks like so you can help me, I'm scared :(  http://gyazo.com/c4b8191a58f5940082227c6623fa9f7a)

To run at a certain frequency, you need a minimum voltage, or it starts to cause miscalculations. Raising the voltage increases the maximum frequency before you hit those errors.

So long as you don't raise it lots, you'll be fine.

does it happen with with onboard graphics(in case you have a port on your motherboard) too? If it still does, problem can be with your cable or monitor.

No the pixels are gone after reboot but I'm just concerned if it will happen again. :)

if increasing the voltage had your problem solved, then nothing to be worried except for psu as @someone somewhere said, not a great quality psu. Where as increasing the load by OC your gpu on your psu with not better quality thus increases the risks of frying your further components. Anyway, looks you are good for now and keep us updated if the problem still there or solved.

Yeah I turned it up and it's fixed now. :)  And I'll replace it sometime when I got the money.
