Replace the CMOS battery (it's old)

Start with replacing the CMOS battery. Also you might want to get a different GPU that is confirmed to be working. The onboard VGA could be dead, along with the 9800 (unlikely).

Also, the CPU could be broken. My only suggestion for this is to try a different (slower) CPU. The motherboard may have issues with higher speed CPUs, although, I don't know.

Last thing to check is that everything is plugged in. I had a computer where the fans spun and all the lights came on, but it wouldn't post. The CPU power cable had been disconnected.

I tried everything, and nothing worked, so I went out and bought a new board, the K8V SE Deluxe.

Same thing.

Just as I was about to go crazy I tried something, I plugged into the system the RAM that came with the board (2 sticks of 256MB DDR400) and it booted up just fine.

Now, I know that the sticks of 512MB and 1GB DDR400 I have ARE working, but they are just not working with ASUS K8V series boards. Why? The RAM that worked was single sided, the RAMs that did notw ork are double sided. Is there a weird memory density limit with K8T800 and K8M800 boards or something?

I'm going to take a wild chance and say all four DDR sticks I tried in these motherboards were faulty to begin with, so I am going to order two more sticks of 1GB DDR400 for this build. Another part of me is still worried that there is a strange RAM density compatibility issue here.. I've read threads dating back to 2004-2005 that say things like double sided DDR sticks are recognized as two banks and two double sided sticks won't run at 400MHz etc? This conflicts directly with the RAM configuration information in the manual:

Regardless, I'm going with 1GB Kingston Value Ram DDR400 sticks.. Any other suggestions?

My gosh, when I read the title I thought of that ex-country of that same name and almost got a heart attack. 🤣
Guess I should stop reading news like this : auto translated to English.
