I am having trouble with a friends computer ... his computer was becoming unresponsive with up to an hour start up times before he was able to use it. We tried to run anti-virus software but wouldn't complete any scans.
We decided to go ahead and save all the files he needed and do a complete system recovery f11 (format hard drives back to factory settings) when started it takes about an hour or two and hangs up at 9% and will go no further. Left it overnight to no avail. could anyone please help as to what may be the problem and how to fix it. Thank you for your help!
