Killer Instinct 1/2 jamma help!!!!!!!!

Okay i just reached the end of my patience, so the last straw is asking for help! I have a killer instinct 2 board and hard drive, the hard drive is working but the board is a cop-out. I get the usual blue-screen syndrome when I boot. So are there any suggestions out there, id particularly like to hear from anyone else who owns the game, but any input is appreciated:D Just to reiterate, it isnt the hard drive!

Anyone with any parts, boards, drives, marquees, cpo's, cabinets for sale please let me know..........
