A7N8X Mobo locking up at the beginning of POST (help)

[Georgieo00]

Hi,
I have a home built computer that is a few years old. Recently I put it in a new case and it was working fine for a few weeks. Then all of a sudden it stopped recognizing one of my RAM chips so that I only had 512mb instead of 1gb. So I took it apart and reseated the ram thinking maybe I knocked it or something when I changed cases. Well, when I went to boot up It decided to lock up at the splash screen of the POST. I tried unplugging everything and trying different RAM combinations on the motherboard and it still did the same thing. I even reset the CMOS but still no luck. I recently bought a new stick of memory, 1gb, and it seems to be doing the same thing. Is it my mobo, psu, memory or something completely different?

SPECS
mobo - A7N8X Deluxe
cpu - amd athlon xp 2400+
mem - 2 512mb pc2700 elixir (original mem), 1gb pc2700 pny (new mem)
Graphics - geforce 5750
PSU - 480WATT Ultra x-connect
HDD - 1 60GB EIDE, 1 160GB SATA

Let me know if you need any other info.

I got my memory tested by the geek squad and they said it was bad but they also mentioned that the memory ports on my motherboard could be bad. Any suggestions?

I also managed to find my old memory stick and I tried that but alas still no luck.

I suppose realy the only thing left to be causing the problem is your motherboard.

Agree. Swap out the mobo and see what happens.
