I've been continuing my escapades with my 11-year-old HP a1640n pre-built which uses an Asus P5BW-LA motherboard ("Buckeye" variant which has Intel integrated graphics) running Windows XP Pro SP3. I recently updated the motherboard BIOS from 3.08 to 3.17 and I noticed that the "PCIe" option under "Primary Video Adapter" disappeared (now I just have the options Onboard and PCI). I have been trying to get this graphics card to work with it:

However, whenever the card is installed in the PCIe x16 slot, there's no video signal or sounds playing whatsoever. Not even the BIOS screen. I took the card to a local computer repair shop and they were able to get a signal with it when it was installed in one of their machines, so the problem wasn't that the card was broken. I also tested out the DVI-D to VGA cable at work and it worked fine, so that wasn't the problem either.

Is my motherboard completely incapable of running a PCIe graphics card, or is it just incompatible with this one card for whatever reason? Is there a BIOS for this particular board newer than 3.17? I've seen a 5.08 BIOS, but that appears to be intended only for one of the "Basswood" (no onboard graphics) variants of the P5BW-LA.

  • Sounds like you should roll back the firmware to the earlier versiob – Ramhound Aug 27 '17 at 5:16
  • I was having the same issue with the card on BIOS 3.08, even when the Primary Display/Video Adapter was set to PCIe. – Pete Aug 27 '17 at 5:32
  • When you said you took "it" down to the shop you mean the pc or the card? Have you tried the card without using a DVD-D to VGA cable? – Ramhound Aug 27 '17 at 5:58
  • I meant the card. And I'm not sure how you can use a card without a video cable unless you mean using onboard graphics instead when the card was plugged in. In that case, there was no video signal from there either. – Pete Aug 27 '17 at 14:18
  • I meant use a DVI-D cable connected directly to a DVI-D port on the monitor or use a DisplayPort – Ramhound Aug 27 '17 at 21:11
