For older Dell PCs, you may need a BIOS update to use cards above the 600 series, as they require the new UEFI BIOS released in 2013. You'll need to contact Dell support for an update if available. Please check the back of the PC case for the service tag, then go to the Dell support page, enter your tag, and look for the downloads for your PC. If a BIOS update is available, it may be listed there, with instructions on updating the PC.

There are zero issues with 750 TI and 390. Something else is wrong. Power supply is the first suspect. Older Dells DO NOT need a bios update to work with nvidia cards.

ATI cards past the HD 4000 5000 6000 7000 8000 series Do not work due to not supporting MSDOS VESA video mode 103.
