Hi, I think my motherboard is f*$!$, you get the idea. I build this system about 6 months ago and everything was working fine. Specs are: Asus P4P800-E DLX P4 2.8C 2*512 (Dual Channel) Corsair DDR 500 ATI Radeon 9800 Pro 256 350W Enermax PSU Have 2 HD and one Optical drive I recently installed a TV tuner card and this problem only occured afterwards, but after removing the TV tuner, still have this problem. The problem is that it only half POSTs, and it's inconsistent. Over the last two days I got it to boot once, but it kept varying, sometimes it would detect the drives and then halt, sometimes would halt sooner, but then it reached a point where it would say "Checking NVRAM..." and just stop there. I did let it sit for over 30 minutes and nothing happened. I tried resetting the CMOS via the CLRTC jumper, now all I see is the lovely ASUS logo and get no further with that. I've tried pulling out everything and I still get nothing other than the logo screen. I've tested the RAM and graphics card in another system (the one I'm on right now :)) and everything seems to work fine. Unfortunately, this is an AMD system I built a while ago so I can't test the CPU here. So I'm pretty sure it's either my CPU or motherboard, but at this point, I think it's the motherboard. My CPU is very well cooled and I'm not even overclocking. I was hoping maybe someone had any ideas on this situation before I take the whole thing apart to bring the motherboard back where I bought it. Thanks for any help out there.

Had the same problem myself a while ago and it was the Asus board. Tried another one and it did the same after 3 months. I would say get another board and maybe not an Asus...

Can't speak for asus mobos with intel CPU's, but I've built numerous computers with asus mobos using the amd cpu and have never had anyone come back yet. However, I would tend to agree it sounds as if the mobo might be gone. When all else fails beat the $%!* out of it!!!

You say your RAM sticks are DDR 500? If you mean DDR2-533 (PC2-4200) Then you should have taken a look at the specs of the motherboard since those sticks are not supported.

i think the bios got screwed up david

No it's DDR500 and the board supports it. Even if they were 533, they should still work but only run at 500. I'm using them now in my old computer which only supports 266. But like I said before, everything was working fine for about 6 months so it's not a compatability issue. I thought maybe the BIOS but I can't even flash it if I want to. It halts before I can load a boot disk or get into the setup screen. I got an RMA on it today, they said it should take two weeks, hopefully I was right and they'll send me a new one. Thanks for the advice.
