Hello, and welcome to THG.

I have has the same issue. There may be a register error in the system. Have you overclocked? If not, perform a diagnosis on the HDD with the install disk.

First disconnect any unnecessary hardware that is not needed to boot such as sound cards, network cards, and any unnecessary drives that are not needed. Also if you have more then one stick of RAM try using just one stick for the time being. Next you will want to reset your bios I would just take the battery out of the motherboard for a minute or two with the computer UNPLUGGED.

Now make sure in your bios you have it set to boot from the CDROM first then reboot from the windows disk. From here you either do a recovery mode or reinstall windows I would recommend just doing a clean install.

A good rule aof thumb anytime you upgrade or replace any hardware reset your bios before booting up with the new hardware.
