Recently I had dome problems with my ACER XC600. One day, I logged in to my desktop but I couldn't use my keyboard and mouse. I checked everything and finally the keyboard is working. The computer was up but hanged for an hour. Later, I found that the battery inside the mouse had melted. I replaced it and tried but it did not work too. I tried with another new battery and finally the mouse worked. The desktop remained hang and I had to do a hard reboot as the Ctrl+Alt+Del Keys do not work. When I switch on the computer, this error message came out "Acer computer error: Repairing disk errors. This might take over an hour to complete." After a few hours stucked with this, I did another hard reboot. This time, the computer did an auto re-install. I was given a choice to reinstall the windows drive or all the drives. I chose the Windows drives. When everything was up, I reinstalled all my programs but I couldn't install my printer as it comes under my previous user id. Whenever I tried to reinstall my printer, it said the printer is existing. However I am unable to print or scan as the printer appeared to be not connected.
Questions: How do I reinstall my printer drivers and remove the previous printer installation under the old userid which I cannot access already? Thanks in advance for assistance in the above issue.
