Yes before i updated to the latest bios version 1.32 i was able to use my Nvidia Geforce GT 520 PCIE x16 and my PCIx1 Nvidia Geforce GT 610 at the same time to run 3-4 monitors but since updating to the BIOS version 1.32 when I try it loads a blue screen saying my BIOS is not fully ACPI compliant! Anyone know what the heck is going on?

Go into the BIOS and make sure ACPI is enabled. If that doesn't work, you may have to roll the BIOS back to the older version. Check with the motherboard manufacturer's website to ensure they have an updated BIOS that will work with ACPI. Because ACPI handles power management and Plug and Play devices, that's why your video cards no longer work.

That's not configured in Device Manager. You'll have to boot into the BIOS menu in order to ensure ACPI is enabled. You didn't mention what kind of computer you have -- the key you press to get to the BIOS menu depends on your system. It could be F2, F8 or some other key.

 

To roll back the BIOS, flash it back to your older version. If you saved it (always a good idea when updating the BIOS), you can use that. Otherwise, you'll have to redownload the older version.

From the tech manual on how to flash the BIOS: http://www.manualslib.com/manual/275291/Hp-Compaq-Dc7800.html?page=94

 

If you are flashing the BIOS from Windows, you must disable all antivirus programs: http://h30434.www3.hp.com/t5/Other-Desktop-PC-Questions/Updating-dc7800-BIOS/td-p/431233

It's still a good idea, and it may not alert you if it does interfere. If you are going to flash it from Windows, you may also want to boot into Safe Mode first.

You want to ensure that nothing in Windows is interferring with the installation of the BIOS. Putting the machine in Safe Mode disables all unnecessary drivers and services, so the computer runs only what is essential. You could also try booting into the BIOS itself by pressing F10 at boot up, and updating the BIOS from there. http://www.ehow.com/how_6960327_update-bios-dc7800.html

 

Removing the CMOS battery will only reset the BIOS to the default settings. It won't take it back to the old version.

Warranty or no, I think a call to HP tech support is in order.

 

For future note, updating the BIOS should only be done by experienced computer users and technicians, and only if there are hardware issues that only a new BIOS will fix. It's not like installing a program or even updating a driver. Botching a BIOS update can essentially destroy your system. And because the BIOS sits on a chip, the only way to fix it now may be to buy a new motherboard.
