Hey guys,

So my 560 Ti died and I have decided to buy 750 Ti as a replacement. I installed it today and everytime windows loads, pc crashes and restarts. I tried reinstalling windows, drivers through safe mode, updated bios, but nothing helped.
There's also a strange thing i noticed, that if I dont move my mouse, OS loads succesfully and doesnt restart for a few minutes, but as soon as i move the mouse it restarts.

PC specs:

i5-2500k
MSI P67A-C45
CFT-650-14CS PSU
4gb ram

Any help is greatly appreciated.
