diagnostics card ... how to figure it out?

[MikeLandry]

I bought an LP50 diagnostics card at

http://www.just4deal.com

to discover what is wrong with my computer.
However, I have had difficulty in using the card. I do not understand how to use it.

I have installed it successfully, but whenever I turn my computer on with the card installed, it shows code "FFFF"
I am not sure what the pdf files are supposed to be used for.
Could you please clarify how I am to determine what is wrong with my computer?

If you'd like a bit more information, when I turn the computer on, the fans power up, the motherboard LED is lit, but nothing appears on-screen. The computer doesn't accept any keyboard input, as pressing any of the three lock keys doesn't produce status lights for the caps/num/scroll locks.

Suspect that it is a POST Code card. When the BIOS reaches certain spots during POST it writes a completed location code to the card and latches it so if the machine fails you'll know the last good test point.

The PDFs probably tell you how to use it.

The FFFFs indicate that post never got to a point to latch a code in the indicator.

It sounds like the board is not processing. Drive action and fan action are separate from processor action. It can be power supply, M/B, video, or processor. Time to start removing stuff to get back to the absolute minimum. No drives, no floppy.
