yep, it was working fine, the last game was mark of the wolves, there is extrange issue :S, i have another boards with work ram error, but this one doents show any kind of message, only a flickering screen with rotanting color pixels
If its giving colored blocks from power on with changing colors and also a clicking sound coming from the speakers its most likley the Bios. Make sure its seated correctly in its socket.
Its possible the Bioschip has broken or currupted, you would need a new bios to confirm. You could try swapping the bios with the other board that gives the work ram error and see if it boots then.
