xp won't reboot while windows is loading

Windows xp home edition Brand new motherboard Brand new hard drive Will not boot up on its own F2 key will get it to boot sometimes f8 key does nothing Tried reformatting hard drive--and even while loading windows-it will not reboot when windows needs it to reboot to go to the next loading step It sounds as if it is booting up but the screen remains black Could it be a bad copy of windows Could it be a bad vid card I have tried every fix i can find on line and nothing works Once it is up and running it runs perfectly-no shutdowns or freezes or any other problems
