I recently recovered this PC due to many viruses. It is running Windows ME and all seemed fine after the recovery until we downloaded LimeWire. It locked up so the only thing I could do was hard boot it. Unfortunately I cannot get it to boot back up. It powers up and goes as far as the memory check but will not go into the F2 bios?, or anything past that screen. It did go past this once but would never load past checking PCI something ? Is there any way I can recover this PC?
