I have a DX4870-UB318 Gateway Computer with onboard Intel graphics. there is a free PCIe-3.0 slot.
I just purchase a new PNY GE Force GT 710 2 gig video card. This card only requires a 300 watt PSU, which I do have.
When I isntall the card, it freezes at the BIOS splash screen for a few minutes, until it finally comes up with a screen providing details of the card - just what kind of card it is, memory, etc. Leaving it sit longer, doesn't appear to get any further along in the boot process.
If I take the new card out and switch back to the onboard graphics, it works again.
I installed the latest version of the BIOS for this PC from the Gateway site, hoping that might help or provide some additonal options - such as turning off secure boot, which could be the cause based on some of what i have read.
Does anyone have any ideas on how to get this working?
