What are you getting stuck on?
When you turn the computer on I'm guessing windows does not boot, it could be your MBR is damaged, a system file is damaged or the bios can't see a harddrive, please post carefully next time and please help me more with your problem by listing exactly what happens.
Try take the C-mos battery out of the motherbored and put it back in, this might work, it will save you time coming back and posting.. so try this if not, repost.
