Hello everyone! I have a problem.
3 months ago I bought almost all new components for my computer. Only thing that stayed the same was my graphic card (GT X560 TI) and power supply (I bought it 5 months ago and it has 650W). My new computer worked great! I bought intel i7, some very good gigabyte motherboard, ssd, 16gb RAM and second monitor.
My problem happened 5 times for now. Sometimes, while I am playing League of Legends(the most demanding game on my PC) my screen goes black for 2 seconds or less(sound stays) then sound disappear and 5 sec after that my computer restarts. Have in mind that I play this game and some other games every day BUT only few times this happened. After I start my computer again it will restart in 5 minutes at max (if I continue playing League of Legends). More it restarts, the shorter time will be needed for next restart. If I leave it(dont play it that day) or I play somthing else, everything will be fixed. Sorry for my bad English. I hope somebody will help me. Thank You in advance!

Thanks for replaying. Well my first guess was temperature. So I watched CPU, motherboard and gpu temperature. They are all normal so it isn't it. And from the first time this problem appeared I opened my computer housing (I have no idea if that's the word for it) so everything cools better. The only thing that I can't know the temperature is power supply. But is it possible that it restarted like the way I told you? Shouldn't my computer turn off immediately if power supply overheats? My model of power supply is LC6650GP3 V2.3 - GREEN POWER

My radeon hd 7770 started doing that, after a week the card basically exploded. I got bluescreen error 116 beforehand. You'll know if this happens if you see a bright light and smoke eminating from the case.

Are you trying to put fear into somebody?

If temps are not the problem the psu might be,in the next topic is something said about it,
http://www.google.nl/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CDAQFjAA&url=http%3A%2F%2Fwww.tomshardware.com%2Fforum%2F290727-28-power-lc6650gp3-green-power&ei=H5olU4ufCqjOygPw7YGYCA&usg=AFQjCNGRiRTA-WsXToerpS5hxOVtCFFBGw&bvm=bv.62922401,d.Yms&cad=rja
basically it seems to be a crap psu.

You could still use another (?) program to monitor the temps like hwinfo32,
http://www.hwinfo.com/download32.html
open it,check=V sensors and click run.

Within these values you can also monitor the rails of the psu and see if one is out of specs,for instance the +12V rail must be within 11.4<->12.6V.The + rails can deviate for no more than 5%,the -rails for 10%.Big "jumps" like from 11.7<->12.3 are no good either.The min. and max. values are kept in the program.

I don't know ho to make it clearer,but i'll try.

If you double click the shortcut there will open a little window,in that window you can put a "V" in the box for sensors,after you've done that you click "run",it's that simple.
Somewhere in the next window you will find values for the psu.

Get some advice about a new psu before buying it so that you don't end up with a similar product.It's probably best that you start a new topic about that.
