Installing drivers crash PC



I'm not totally sure this a driver issue but installing the drivers work as detonator, my issues is the following. Out of nowhere (as far as i know) one day when i turned on my PC and it was booting fine, i got to the windows logo and just before reaching desktop, my mouse lights started blinking and then the pc restarted, after i few tries of the same thing, i tried to troubleshoot so i disconnected the GPU and booted using the integrated graphic of the motherboard, the pc booted just fine, i connect the GPU again and the issues came back.


So now i know is has to do with the GPU. i could boot to safe mode with the GPU connected so i did that and unistalled all the drivers and restarted, the PC booted fine and just to be sure i reinstalled the drivers to see what happen, and surely the issue came back, same thing. the PC boots, windows loads and before reaching desktop it freeze and restart. I think the drivers are causing the problem even tho it doesnt make sense. So if anyone have any idea of what i should do please share.


My Specs are the following:

Power Supply: CX500

GPU: Randeon R9 270

CPU: Phenom II 965  3.4Ghz

Motherboard: GA-78LMT
