Something is not working wright!

[Rumpaduham]

So November 2013 i bought a new GPU, and a PSU. For 7 months everything worked fine. My PC was just amazing.

But now in May, one day i returned home from school and my PC just didnt turn on. When i pushed the start button then fans spinned and nothing happened.

Well the first thing i did was to take my PSU to a guarantee. They gave me a new one and everything worked fine until something happened to my GPU. I took that too to a guarantee, and they gave me a new one too.

Now i had both parts new again, i put them in my PC everything was fine untill i tried to launch a game. When i tried to launch Watch Dogs the computer turned off. Ok i thought that maybe there is an issue between the drivers and Watch Dogs. So i tried Far Cry 3 and my computer turned off again. Although the settings on both games where set to low. So is it something with my Motherboard or my Processor or my PSU or GPU?

Or is it something with Drivers? Please Help!

Ram: 8GB
HDD: 1TB Seagate
CPU: Intel i5 3350P


So I think that my PSU is more than enough. What could couse my PC to turn off? Well when i put my Nvidia GT630 everything works fine.And i dont have a extra PSU to test.

And the temperatures seems to be fine.
Cpu temperatures while playing goes 60C - 70C
And when i have the GTX 760 it stays 30C

Thanks for the help!

The gpu stays at 30c when playing a game? That sounds very wrong

[Prokart2000]

is it running on intergrated gpu

No the Gpu stays at 30c when not playing a game. The problem is that i cant play games with my GTX 760.

Cpu in my opinion is to hot, reduce overclock, check the heatsink and the thermal paste
