Thread: System keeps restarting

I have two computers Lenovo with window xp sp2 but it causes the problem boot to desktop it will restart itself. I remove HD and RAM to working structure and it comes up well but need to get if there are other thing to do in this two system in order to put an end to this self starting.

If this hard drive was originally from another working (or nonworking) system, then it will not 'just' work on another system without at least 'repairing' windows and then probably updating/correcting driver issues. You can only 'just' move a hard drive to a system that is nearly identical to the first one.
