I have an old HP Pavilion a6244n, and the original graphics card (NVIDIA GeForce 8300) crapped out a few years back. So after a little hassle, I was able to use the on board graphics to get by.
So I decided i wanted to get a semi-decent card installed. So first, I installed a new power supply (Thermaltake TR2-430w). Everything is fine and works with the onboard graphics. Then I uninstalled the old geforce drivers, disabled the onboard display adapters and installed the new card. But the new card isn't being recognized by the monitor. I'm sure that power to the monitor is good, that the monitor works and that the rest of the computer is set up fine, because if i remove the card and plug back into the onboard card, it still works.
The one thing everyone says to do, is go into BIOS and delete/disable the onboard graphics, but my BIOS (Phoenix tech, v 5.23) doesn't have that option. It only allows you to set a primary, which I've set PCI.
Can anyone help me trouble shoot this? I'm willing to bet I have to find a way to tell my motherboard to ignore the onboard grahpics card, but BIOS won't let me. Anyone have a work around? Thanks in advance!
