Ok , So I bought a Dell xps 8500 in september 2012 with the following specifications:|
Processor - Intel Core i5 - 3450 3.10 ghz
ram - 8 gb
Graphics card - gt 640 1gb ddr3

I upgraded to Zotac gtx 660 2gb ddr5 synergy edition and i am having some problems

So I was playing Crysis 3 with high graphics and suddenly the pc crashed and then it kept restarting (it didnt go far the "dell xps 8500" screen btw) i plugged the switch off and gave it some rest , but still when i switched it on , it kept restarting like before then i opened the case and touched/pushed the gpu a bit and then the pc started working

again i played crysis 3 at high settings and after like an hour it crashed and again kept restarting like before!

i opened the case again and moved the grafix card

and it worked again

so what is the problem ?
It doesnt seems to crash when i'm just browsing or playing online games
but when i play real pc games ,it crashes (havent tried with other games though)

My psu : 460W
Required for gtx 660 : 450 W

the difference is just 10W , so can it be the problem? should I upgrade my psu as well?

or the problem is overheating? i touched the grafix card just after opening the case after it crashed

and it was kinda hot

please help!

Edit 1 : Drivers are up to date and I have installed GPU - Z and I get the following http://gpuz.techpowerup.com/14/03/19/28p.png while 2 tabs of google chrome ,1 tab of firefox , skype are open

Edit 2 : I tried capturing the img of gpu-z while crysis 3(high settings) along with all the stuff that was running(see edit 1) http://gpuz.techpowerup.com/14/03/19/3xw.pngv
NOTE: The Temperature kept increasing but i stopped it before it crashed

Edit 3: ok now i played crysis 3 for like 5-6 mins and here is the max result - http://gpuz.techpowerup.com/14/03/19/bew.png
I will try it without the case tomorrow(after 7-8 hours) and post results

Edit 4:Looks like the problem was that the gfx card was not seated correctly , an engineer came and reseated it and it worked . :)

The psu was going to be my first suspect, but your's seems fine. I would try updating drivers before we continue trouble shooting.

Try removing it and reseating it again, might just not be seated very well.

Hello... Your Graphics card will get very Hot when Gaming at high settings, that heat will also get your other computer Parts hot too... you either have a Thermal shutdown or a lack of Power from your PSU. You need to run GPU-z in the back ground to monitor your temperatures http://www.techpowerup.com/gpuz/

Another simple test would be to remove your case cover, and see if the problem goes away, if it does, you will need a cooling option for your case, to get rid of all that heat trapped in it.

You can run Real Temp in the background too... http://www.techpowerup.com/realtemp/ for a CPU temperature monitor tool.

Hello... 80 - 90 degrees C is considered the maximum to allow your GPU to run... so keep running the GPU-z /Crysis test for us and post picture... also repeat the test with your cover off your case... to compare temps.
