Ok guys i bought this brand new graphics card and many problems started to happen, first no signal to the monitor(then i fixed the problem) and now the computer restarts when i play high end graphics game in like 5 mins espcially GTA IV it restarts in like 2 mins,but when i just surf the internet it nearly never restarts,when i play dota 2 it restarts in 25 mins, when i play battlefield 4 it restarts in 10 mins,when i play GTA IV it restarts in 2-5 minutes. my specs are -

Intel i5 3330 ivy bridge 3.0GHZ
INTEL DH61BF mother board
8gb ddr3 ram
600w power supply model - Lightwave LW PS600
Windows 7 Ultimate 64 bit
Gtx 660 gigabyte oc version

And also i checked the max temperature while playing GTA IV my gpu reached max 55C which is not the problem and i checked all cpu temp and gpu temp and they are all below 60C so the problem isn't overheating, gpu reaches like 55-57C and then reboots, i don't know how to upload pictures here to show you all listing of the gpu power and voltage so ill type it here

I can't find a lot of info on that power supply unit.
How much did it cost and where did you get it from?
Could be that's your problem

I suspect your PSU... even if 600W is plenty for your sistem, you might have a bad PSU.

Thats a cheap PSU :)  its definatly your problem... 600W yes, ist enaugh for your sistem, but with a GTX 660 OC you need like, hmm arrond 40A /12v rails, i am not sure if your PSU can handle that (it mighta have 600W overall, but i dont think that it can supply enaugh amps tou your card)

Just a simple comparisson. A decent (above average) brand 450W PSu can cost as much as 50$, so, your 15$ 600W PSU its....hmm.

Sounds like a POS power supply.
How many amps does it claim on +12v?

In any case that is most likely the problem.
Stick with Corsair, Seasonic, XFX and some Antec models

Try to get a 80+ certified PSU because they are generally better quality.
