Hi all. Newbie, here! I tried searching the forum for problem similar to mine but it seems that when it comes to Mobo and RAM issues there could be many possibilities. So this is one last attempt for information before I get a replacement Mobo.

Information on the system:
HP Pavilion 513n – 1.8 GHz/400
Motherboard is ASUS Model PAG533-LA with onboard Video Card
Shipped with 256MB or RAM

I was trying to give a boost to that old clunker by adding more RAM (increase from 256MB to 768MB by adding a 512MB stick). HP’s site said that this system could handle PC3200 DDR 400 RAM which is what was brought for the upgrade (later we found out that this new RAM was obviously not compatible with the
PC2100/266mhz/256MB stick that was already there).
  • We put the new RAM 512MB/400 stick and powered the system. Power came in but no display. And there came a faint smell of burn. We powered off immediately.
  • Remove new stick and put old stick RAM 256MB in slot 1. System and fans power briefly then die. Put old stick in slot 2 and same things happen.
  • Tried powering system with no RAM at all. System powers up OK but with continuous long beep. No video signal (monitor on amber) and no POST.
  • Tried powering system with known working RAM stick (PC2100/266MHz/512MB) from friend’s system. System powers up OK. No beep. But still no Video signal (monitor on amber) and no POST.
  • Since this Mobo has no jumper for clearing CMOS we tried clearing the CMOS by removing battery (and leave it out even overnight). Then powering it with the known working RAM sticks. Same result as step 4 above.
  • Read in other forum that perhaps Video card burned out and got a PCI video card and powered with known working RAM sticks. Same results at step 4 above. Since we can’t access the CMOS we cannot disable the onboard video card.
At this point I am thinking that the old RAM stick that was in the computer must have gone bad. But what about the video card or the Mobo? Is there anyway to
test those before we consider buying a new Mobo? Any light you can help shed on this will be truly appreciated.

Thanks.

Hello and welcome to Bleeping Computer.
I have installed several upgrade PCI (Old PCI) cards in HPs and each time the BIOS sensed the card and automatically disabled the onboard video. Make sure the card it inserted in the PCI slot closest to the CPU.

Unplug the system, open up the case, and sniff around to try and find the source of the burnt smell. That's likely to be your problem.
