Question : Problem: What does the "FF" motherbord code mean. EVGA mobo.

I received a pc that is going through post,EVGA logo, & windows start up, extremely fast. Then it goes to black screen with "FF" on the motherboard. I tried the board with tested memory. I tested the power supply with a power supply tester. I tried Puppy Linux, Unbuntu, & Suse. It sounds like they finish loading but just the black screen i the end.
Any thought would be appreciated.

since you had the problem also with Puppy Linux, Unbuntu, & Suse, the hardware is the only portion left.
strange the disk tests good...
