Hello !

Not a while ago i both new graphics card ( GeForce GTX 650oc ) for my old pc, but when I starting to play (Gw2, Lol or other games) after 30-1h my pc keeps shutting down and restart himself. So my question is : What should i do?

- GeForge GTX 650oc
- Gigabyte GA-870A-USB3
- AMD Phenom(tm) II x4 840 Processor ( 4 CPUs), ~3.2GHz
- Mushkin DDR3 PC3-10666 1333MHz Dual Channel (2x4096MB) 9-9-9-24 @ 1.5V
- Inter-Tech SL-500 500W (3.3V=30A, 5V=30A, 12V=30A)

How are the temps? Is it overheating? My second guess would be the Power supply, then I would check the ram.

Sounds like overheating to me too, you can use a program to up the VGA card fan speed from the 40% to the 50% stock speed up to 75% to 80%. I use a program from EVGA call Precision I'm sure other there are others I think MSI has one called Afterburner. Be sure all the vents are clear so you get a good air follow thru the case from front to back.

Well if its not a temp issue perhaps it's a power supply issue, do you have another you can swap in to try.
