When I login to my user account all i get is my desktop background. I have a cursor and can move it around but no clicking. I cannot use control alt delete to open task manager. I just did a repair install to fix a previous problem after i deleted nvidia drivers for my motherboard and accidently removed the ones for my motherboard chipset. All of my data is back up so if i need to do a fresh install of windows i can, but would like to keep that as a last resort. Any suggestions as to what i should do?
