Default Problem with my GPU

Hi guys!
I'm having trouble with my new GPU (R9 280x). Long story short. Last month I bought the GPU, but couldn't use it because I had a shitty PSU. So today I bought a new PSU (Antec High Current Gamer 750w) and I connected the new GPU. First boot is ok, used to have catalyst, so no big deal about drivers. But when I opened a game it crashed before it even started.
Then I restarted the PC, but I couldn't boot past windows 8 logo. When Windows 8 user password screen should come, my screens starts blinking.
I tried using the onboard gpu, and everything is fine. Tried uninstalling AMD drivers, but got same results. Don't know what else to try!

Uninstall all video drivers, run driver sweeper to clean any remaining. Reinstall drivers.

Sounds like a driver issue.

Otherwise you could try a clean install of windows.
