I have been having trouble upon bootup of my XP running desktop. Lately (past month), if there is any removable storage device plugged in (ie memory card plugged into the port on the printer, cd in the disc tray, etc) the OS will not load. It just sits there will a black screen and a blinking cursor. Now if I remove the CD or the memory card it boots up fine, but it has NEVER done this before this past month. Is this an issue with the bios, a virus, or a hardware issue?
