The finding was not good. To see what we found, type BAD CAPS on google.com. A new motherboard was the cure for them.
Its also possible your machine doesn't support XP 64. Not all machines run this version. Did you talk to it's maker?
I have a problem with my xp 64 pro, when restarting it doesnt detect ACPI. I have to restart x number of times until finally it recognizes acpi then starts normally. It does this EVERY time i have to restart. Any clue?
