I'm trying to help restore my wife's grandmother's PC back to factory default. It seems her teen grandson somehow got it f*d up big time w/ virus infections to the point I can't run McAfee or install AVG. The pc is a Dell Inspiron 570. It doesn't have a restore CD, but does have the restore partition. From instructions I've found online, it would seem I need to hit F8 during boot and from the advanced boot options choose Repair. When I do this, it then goes blank and then finishes loading to the desktop rather than letting me get to the next set of options for restoring. Looks like the virus has really gotten a hold of it. Any help getting it restored is greatly appreciated.
