It's been a week of laptop problems for my father. Don't know how he does it, but he manages to pick up more viruses than a Petri dish. Or a hooker. (See, I offered both the high and low road for that analogy... and will I ever be thanked for providing this particular courtesy?)
Scrubbed the hard drive, removed something called "Vista", and finally found the drivers needed to install XP on his Toshiba (slipstreamed SP3 and SATA drivers with XP to create a new installation disc). Operating system is hunky dory, but driver conflicts with his broadband USB modem now persists. Oh, joy!
