So the story goes, that my pops goes out and buys a brand new computer, and we both get the think working without a hitch. But then the computer crashes when my brother was using it, and it hasnt been usable since. The monitor doesnt recognize the computer, even though the computer turns on and runs just fine. Here is the computers specs:

Motherboard: Gigabyte Geforce GA-K8N51GMF-9
Processor- AMD 64 3700+

Ram: 512 mb

Keyboard: Some Ben Q keyboard, that may have been the reason for the
comp to crash (Accidental hit of the Power button on the keyboard)

Monitor: Ben Q FP93G X

Help would be very great!
