Question about ASUS P4S800-MX Motherboard

1 Answer


Dear Folx,

I bought this ASUS P4S800-MX at G&A Computers in Waco, TX, and it
was a DOA board. Sent it off for RMA and came back during the holidays.

On January 20th the system was working great, then the 24th its acting
up. Then after reinstalling the graphic card, and rebooting into VGA mode
it gave a blue screen of death, and then a blue screen and green stripes.

I had the XFX 6200 graphic card installed in Dec of 07, then the graphic
card "blew" up, and I replaced it with a known working ATI Radeon 9000 64mb then it worked ok till today and now it won't boot. The CPU Fan and
and the devices connected work, but no post, no beep. Has there been
any historical issues with this board? I'm so confused? Please Help?

I sent word to AsusTEK about this because this is the RMA replacement
from the original board. I flashed the BIOS, cleared the RTC / CMOS,
only thing I got connected is the network card, sound card, and AGP
graphics card.. and the mobo.. no post, no beep.. *sigh*

Re: ASUS P4S800-MX Boot / ISSUE

I'm sorry to say that I had much the same problem with a RMA'ed mobo from Asus. The one that came back worked for a short time, and then died.

I can't say that Asus is the only one I've had the same problem with, Intel has done the same. But I kinda expected more from Asus. I did not bother again, I just decided to do a mobo/CPU/memory upgrade at Fry's.

PC wont boot, not even to bios

Maybe the mobo is shot for u and he has his PSU shot.......Check for any burnt smells from the mobo. See if the cable from the PSU is properly connected to the mobo. Try removing all drives like graphics cards, RAMS one by one and see if it works.

The problem is most likely bad capacitors. The may have used a bad batch, with many people having such issues. I understand it is difficult to get several of the caps out without ruining the board completely, so it may not be worth the time and effort it would take to replace them.
