HP Compaq DC7800 Convertible Minitower PC


Recommended Posts

Hi guys

I'm having an issue with a HP Compaq dc7800 Convertible Minitower PC where it doesn't post or start an install of any windows Vista/7/8 apart from Windows XP. I've also tried to test it with Ubuntu but it crashes aswell. I've pin pointed the issue to be with the NVidia Quadro VS 440 card that's installed in the machine as once removed and using the onboard graphics then all works fine. But I would like to keep the card as the plan would be to use 4 monitors,

This is the BSOD that gets generated with the card in.

"The bios in this system is not fully ACPI compliant"

I've updated the BIOS for the MOBO in the system to the newest available from HP. But no luck.. I've also gone in a search for the NVidia NVS 440 bios update but no luck with finding any. Any help or tips?

Do you mean Quadro NVS 440? According to nVidia's website. These are the Windows Vista, 7, 8 drivers for it:

I've used Windows XP, Vista & Windows 7 on an array of different DC7800 SFF which I believe share the same motherboard as the mini-tower without issue. We had HP OEM Nvidia NVS 285 or NVS 290 though.

See if manually map IRQ addresses helps (Keep SATA, LAN and Video on separate addresses; e.g. 5, 10, 11), save, power off & back on. Some machines would fail on ACPI related issues until this was performed. You might be able to flash the bios to another vendor/OEM on the card but do so at your own risk.

Can you install the OS without the Quadro and then reinstall it once the install is complete?

Try it in another slot?

Been there and done that and it doesn't make a difference. In that the minute the NVidia card is in. Its just bluescreen after bluescreen on boot.

As with regards to another slot, there's only 1 PCIe x16 on the mobo.

Yes, sorry. Slight finger slip. It is a NVidia Quadro NVS 440. Its actually got HP Part numbers but when I access the details through HP support site (http://h20000.www2.h...eriesId=1152210). There are no downloads available. But as NVidia has drivers for the card, I'm left stumped on what's going on.

This will be my next step I suppose.

Is there another PCIe slot that you can just try it in to see if there's a difference?

Unfortunately not as the machine only has 1x PCIe 16 slot.

I've tried IRQ changes in the bios, but still the same result. :( what on earth could be happening?

    • Could you come up with a slightly less depressing background for Tux instead of that gray gradient? Doesn't have to be cheerful, just less of a downer...
    • Linux 7.2's first release candidate gets off to a good start by Paul Hill Credit: Larry Ewing It has been a few weeks since the release of Linux 7.1, and in that time, the Linux 7.2 merge window has been open, where developers can submit their features and patches ready for the upcoming release. That window is now shut, and the release candidate phase has begun so that new features can be tested and further fixes applied. According to the founder of Linux, Linus Torvalds, this week’s release candidate looks “reasonably normal”. Although we are super early in the release candidates, this is a good sign as it makes it more likely that an eighth release candidate will not be needed. Torvalds even mentioned that the update’s stats are only larger than they really are because there was another AMD header drop with a third of the patch just being AMD GPU register definitions, which aren’t big changes but make the code contributed look larger overall. In addition to this, he noted that just over half the patch is drivers, even when excluding the AMD register dump. The rest of the changes are spread out over architecture updates, tooling, documentation, and core kernel updates. In the next week, Torvalds says that he will be chilling out, taking the week “mostly off”. Despite this, he will be reading emails and keeping up with things, so if he is slow responding, now you know why. He said he is hoping for a calm week, but we will just have to see if the second release candidate is actually like that. We should expect seven or eight release candidates before Linux 7.2 is released, so expect it around the end of August. If you missed it a few weeks ago, be sure to check out our coverage of Linux 7.1's release.
