Are you saying your pc wont boot up into windows?
If so, take out all extra pci cards that arent needed, also any usb that isnt needed.
Then take ram out and clean gold parts with pencil eraser.
then make sure all your other connections are on tight.
Then try booting up.
If no good then take heatsink\fan and cpu out, clean and re-seat with new thermal grease, make sure heatsink\fan is on correct and flat.
