Hi, I am having troubles with my Dell Dimension e510. There was some sort of fake XP antivirus program that was run and now it always gets a blue screen error on restart. The errors change each time from video card errors to beep.sys errors. I have researched around to see if I could fix it, but the problem is, I cannot boot the PC at all, not in Safe mode, not in Safe Mode with Command Prompt...nothing. How can I fix it without booting at least into Command Prompt? I have tried a boot disk..no dice. It says to disable BIOS but I dont know how to do that. I do not have an XP disc because the computer came preloaded...does that mean it is contained on a partition? If so, how can I access that? Any info would be great. Thanks!!!
