Try all safe mode options. Don't leave any untried.
Bob
I have been told by HP Support that I have a virus. Here's what's happening with my Compaq Presario. When I go to turn on the pc it starts to attempt to load Windows XP but stops at a box that basically asks for me to make Microsoft Outlook my default mail box. If you click OK or X out of that box, Windows still will not load. I even cannot get to Safe Mode after selecting it. Should I try selecting Safe Mode with Networking? What is another way to get to my files to back some up, then reload the entire system software, again? Thanks.
