I jump started it by jumping the yellow pins on the board and it comes up with the same message Cable Disconnected DSUB Analog. Any suggestions? Thanks
Step 1- try external monitor
Step 2- replace memory
Step 3- replace power supply
Step 4- remove motherboard completely from game and bench test with a known working power supply and monitor
Step 5- replace CPU
Step 6- replace motherboard
