Strange graphics problem

Well my computer was working fine and i just turned it on and now all the fonts seem a bit fuzzy and also when i click Nvidia control panel then my screen goes blank for a split second .. This didnt used to happen before. Any idea whats going on ? All fonts seem a little but fuzzier and not so sharp as they were before.

Oh and when i turned on my computer, my resolution was resetted i dont know how.. Anyway it was running on the lowest resolution possible so i had to adjust the resolution again.. Anyway any ideas whats going on ?

I always recommend the event viewer first. Start, run, eventvwr.msc press enter
Look for errors. Were there any updates installed last nite?

Ah fixed now.. Had to uninstall and then reinstall the drivers for a 2nd time and that worked. There was nothing in the event viewer though. Anyway thanks
