Reboot Loop

Hello,
I'm having a similar problem as others with my XP being in a constant loop. I believe I had the very latest version on it, but I can't check it out to be sure. I have picked up some kind of virus preventing my IE from working so tried to restore the computer to a previous date. This has failed several times today. But, all seemed to go well finally when I went back a few weeks in this month, it was actually restoring, and then it failed. Now it wants to reboot and is in a countdown mode. It gives me a choice of selections using arrows, either safe mode, previous confident configuration, etc. However, the keyboard has been deactivated. The arrows don't work, and when I try to use the F8 key a prescribed to others with the similar problem, nothing happens. The F8 won't work either. The screen moves back into reboot, counts down, and then repeats cycle. I've been playing with this all day. I have some resume's etc on this computer that I don't want to loose. I have downloaded a XP Reboot CD from the net on another computer, but of course it won't boot with this loop running. HELP. Thanks
