So I bought a new computer, and it was great, but not enough for me. It was an optimal computer, only for 500$. I bought it becouse that was the best computer i could afford. So after some months of collecting money i bought a videocard (Gigabyte GTX760 2Gb OC), just becouse the Geforce GT630 didn't do what i wanted to do it for games. I just wanted to run games on High settings. Ok so long story, short i bought the videocard, i bought a PSU (Fortron Raider 750w). And everything was running just fine. I could play games on High and Ultra settings. But then one day i came home and my PC just didn't react. I pushed the ON/OFF button and it just didn't turn on. I was just freaking out. My friends told me that it was the PSU. Ok after two days the store gave me a brand new PSU. I plugged it in and still my PC didn't turn on. Ok then i took my whole PC and they told me that my GPU is bad. Got that new too in the same store. Ok so i was lucky maybe and they gave me new parts. So i put them in my PC again. Turned the PC on, everything was working just fine. The Watch Dogs came out. I wass all excited, i bought it, downloaded it, and as soon as i start the game my PC shuts off. My heart was just exploding. I started to panic. So i turn the PC on and try Far Cry 3 and it shuts off. So ii check the temperatures, and everything is fine and normal. So i take the old GPU and everything works fine. So can't my pc run the GTX760??? Is it the drivers fault? Or i should down clock the factory clock. I just can't figure out what is the problem with my PC. PC Specs: -Mobo: MSI h61m-p22 g3 -CPU: Intel i5 3350p -RAM: 8gb -GPU: GTX760 or GT630 -PSU: Fortron Raider 750w -HDD: 1TB Seagate -OS: Windows 8.1 Pro x64 O and also the day before my problems started i noticed some weird lag and FPS drops. And if i can't figure out my problem with you, then i am going to change it for an Xbox. Becouse i am sick of throwing hundreds of dollars for Computers, just so i can game. And thanks for helping. Realy. You people are my only chance!

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

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!

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!
