ADDITIONAL INFORMATION

- Display works fine in safe mode.
- Motherboard doesnt come with onboard video
- Video card doesnt overheat, it would idle in the 60's and during heavy gameplay it would be in the mid 70-80's.
- I've tried reinstalling windows, drivers
- Last night i got lucky after reinstalling with 196.21 drivers, system booted up fine, the white vertical lines in bios had gone away, windows started fine at native resolution, then i tried playing my video game and after 10 minutes it fuked up again, and once i restarted all the symptoms returned.
- I've tried uninstalling the drivers with Driver Sweeper from Guru3d, and I've also cleaned my registry with comodo registry cleaner.
