Well that was great, what a **** on ive just had.
Uninstalled old drivers, but when the screen goes black while uninstalling, mine didn't come back on, kept saying 'No Signal Detected', so i didn't know when the drivers were off, so i waited about 5 minutes to make sure, before hard restarting.
Had to do a Start Windows Normally (due to hard restarting), and then had to run the Cat Uninstaller again to remove it, before restarting again, and installing these.
Never had that before, ever, but im on a new monitor now via DP (was on DL-DVI before), so is that the problem, and am i going to have to dig out my old screen, and rig it back up everytime i want to pop new drivers on, or just carry on doing what ive just done ?
