Just build a new computer with an ancient GPU. For some reason, my motherboard is not detecting the GPU. I tried to download the drivers from NVIDIA but it wont install because it cant detect any. I also tried to download just the GeForce Experience but I get a message saying "NVIDIA Installer cannot continue. NVIDIA GeFore Experience requires an NVIDIA GPU."

Since im currently using the onboard hdmi, I plugged in the gpu through DVI to my monitor and tried downloading the drivers/GeForce Experience again but nothing happens. Checked my BIOs to make sure the Peripherals was set to boot up PCI first.

My Build:
CPU: Intel i7-8700k
CPU Cooler: Corsair h100i v2
MOBO: Gigabyte Aorus z370 Gaming 7
GPU: Evga GeForce GTX 580
RAM: Corsair Vengeance RGB 8x2 16gb 3000
PSU: Thermaltake Grand Power 1200w 80 plus gold

Here is a checklist for you :

1. GPU fan running = 2x6port PCIE cables attached properly from your PSU

2. BIOS set to AUTO/PCIE

3. check in your BIOS for PCIE/PEG configuration if it detects your GPU on its slot.
3a. if it says "x16" or "name of your GPU" then your MOBO sees it and your PCIE slot is working fine
3b. if it says "x0" or "empty" or anything along those lines, recheck the pins on the CPU mount. you might have bent one or more pins. use flashlight, magnifying lens (or your phones zoom camera) and a very thin tweezer or thick needle to realign the pins. goodluck! if that doesnt fix it or all the pins were okay in the first place, then im sorry you gotta buy a new motherboard. i believe most shops would charge you...

Can you make sure it is physically installed properly inside the motherboard.
Make sure its tightly installed and there power being delivered from the PSU

Are there any signs of the GPU working? (Fans, LED's)

4. dust on the connector pins/MOBO PCIE slot but highly unlikely since im assuming they are all brand-new. you gotta push that GPU into its PCIE slot with some force (not too much mind) and make sure none of the golden connectors are showing

5. See the "basic display adapter (?)" in your device manager (thats your NVIDIA card before windows update will have a chance to install the driver if youre connected to the internet)
