After installing PNY 8400GS computer will not shutdown, only reboot.

I have recently installed a PNY 8400GS into an older HP Workstation. After installing the card and using the drivers that came with the card the computer would not shutdown, only restart. So I went to PNY's website and got the newest drivers which were the same and still got the same issue. Then I went to NVIDIAs site and they had the same drivers there. I am completely puzzled where to look. I turned of the setting for the computer to reboot incase of system failure and it still reboots when you go to shut it down. Even holding the power button in just restarts the computer. I have to physically pull the power cord out for it to shut down. When you plug the cord back in it automatically reboots. Is there a way I can search for this problem?

Hi There,

I would suggest updating the BIOS for your motherboard. It could be a power management issue.

Could the issue be that it is a 64 bit card and I only have a 32 bit machine?
No this should not pose a problem. 64bit capabilities will only be used if you are running 64bit OS.

I believe the issue lies within the ACPI. Update the BIOS i think this shall fix your problems.

Did you install the drivers first then power off insert the card and boot.
then install the drivers from the manufacture.
Did you turn off the AV during setup and disconnect from the internet?

If you have an onboard video card disable it in the bios.
Check your boot order is HDO first/
What's the PSU watts you have there if the PSU is insufficient to carry the new card windows may prevent you from using it.

Issues with adding new video card to computer that has on-board video.
There should be no issue with adding a PCI-E card whith a motherboard that has an On-board graphics card. The BIOS should automatically detect where the DVI/VGA connection is plugged in!

If this has not happened it may be because the BIOs is not PnP detecting your new card. Update the BIOS and this will fix the issue.

If the PSU is not capable of carrying the power requirements of the new graphics card then it will cause an irregular post beep and usually the BIOS will throw up an error.

I hope this helps. I personally think the BIOS update will fix all of your woe's.

How do I update the BIOS?
