I dont know what model it is as I cant display anything but i am using onboard vga video

The model number will be stamped somewhere on the tower, either on the front or the back. Sounds like its a motherboard issue with no signal and no usb connections. How do you know it doesn't detect any usb devices? If you can't see the screen you won't be able to tell what the system is doing.

Check the DVI cord for any damage.
