When pushing your power button, try to hold it a while for a few times.<br />
Don't hold too long or it will turn off again.<br />
Did you get any beeps from the system? or totally quite ?

Well, when i take the cpu out and turn it on is does nothing. &nbsp;Also i tried a different video card with the cpu in with no luck, and my cpu from my other computer will not fit the broken one. &nbsp;So, it might be the cpu is bad i guess, &nbsp;but i wish i had a way to check first. Thanks for the help.

Microsoft Windows XP is the sixth release of the NT series of operating systems, and was the first to be marketed in a variety of editions: XP Home and XP Professional, designed for business and power users. The advanced features in XP Professional are generally disabled in Home Edition, but are there and can be activated. There were two 64-bit editions, an embedded edition and a tablet edition.
