Hey guys, about a month ago I got an ASUS A7N8X-DX Motherboard with a AMD Athlon XP Barton 2500+, I installed them and everything worked great for a month up till now.

I just got a Vantec Aeroflow and some Arctic Silver Ceramique, and I took off that old stock heatsink and installed the Vantec Aeroflow. Everything seemed to go OK. I turned the computer on and it booted up (Note: Asus POST Reporter told me all this stuff like there was No HD, No Floppy etc, which was true becuase I didnt have them in yet). I was very pleased when I went into the bios and saw that my CPU temp was much lower than before. I then shut down and was eager to install my new Sapphire ATI Radeon 9800 PRO 128MB and I put it in, and turned on, and to my suprise, nothing happened (Note: The RED Light on the AGP Slot didnt come on, so I didnt think it was inserted wrong. My Monitor never came on, just stayed in standby mode, also, ASUS POST REPORTER this time said nothing, although everything powered up, the CPU fan, Radeon fan, etc.) I then thought that it was the videocard so I took it out and put in the old one I was previously using, and got the same thing. I got worried and took everything out of the case and put the motherboard on the desk, and started to attempt to find out what was wrong, I started from scratch and plugged in the power supply for it, turned it on, nothing, the power came on and cpu fan started up, but again no post reporter like I had heard the first time, again I plugged in the Radeon, and no monitor, just standby mode. I then put in ram, etc. and still nothing. Now, I have tried as far as using my old Athlon XP 1600+ because I thought the CPU had died or something, and that did the same thing, same results. Took it out, tried it in my other computer, and it worked, same with the Radeon 9800 Pro, I tried that in my other computer after it had skrewed up my A7N8X-DX up, and it worked fine.

Its like when I plugged in the videocard it killed the AGP slot and fried the mobo, becuase I cant get anything but standby mode on my monitor and I cant get any post repoter like usual. (Yes, my speakers are plugged in :p )

I am very upset about this as I just got all this new stuff and now I cant even play with it, and I may have to wait for another motherboard. ( I guess I could use my old comp but its not the same).

Did I mention I also cleared the bios, left the battery out for 40 mins, held the power button in to drain excess power, then swithced the jumper back from clearing the cmos, and still the same thing. I dont think I damaged the motherboard when installing the HSF, although there is a little scrape on a couple gold lines, but it doesnt even look very bad, I dont think the connection could be lost from it, plus, why would it have worked the first time until I plugged in the videocard?

Anyways, thats what is happening right now with my comp, and I'd love some help.

Anyone? Suggestions? Comments? Is it time for an RMA? Will they even take it back? (I've had it for about a month)

Thanks a lot for your time guys, hopefully I wont have to RMA this board, its a great board, plus, I dont want to wait like a month to get it back.

PS:

If it matters, the ram is Corsair XMS PC2700 256mb (2 of them, but I tested with 1 at a time, all sticks. No change)

Videocard (old one is GF2 GTS 32MB, new is Radeon 9800 PRO)

HSF: Vantec Aeroflow w/ Arctic Silver (NO OC'ing yet, didnt even touch that stuff in the bios, just looked at temps then went to put in videocard, then had a busted mobo )

Did not have any HDs or Optical drives connected, but that shouldnt matter.

Thanks guys -

I've been having the same problem. I got my THIRD motherboard a couple days ago and just rebuilt it AGAIN today, and I tried using an old Mach64 PCI video card I had sitting around just in case it was the AGP slot getting fried or something. And it worked FINE, and as soon as I installed the 9700 Pro it started doing the no post thing again. I removed the 9700 and re-installed the PCI card and now it does get a boot beep and drive check and everything SOUNDS like it's going to boot up, but there is no video. If anyone has any ideas on this please let me know! I'd rather eat nails than go through yet another lengthy Asus RMA.
