Thanks and I'm sorry, it just scared me when I read that. And driver sweeper found problems with my graphics card drivers... if I remove those will I not be able to use my graphics card?
You have to run the verifier at least 24-36 hours.
Regarding the question about drivers. You cannot just remove them, you must reinstal updated ones. I have found these instructions about graphic drivers. The company names used etc. may not apply but the procedure does. You must install new drivers, afer the uninstll or you will have problems with the graphic card and serious problems with the computer monitor.
