Hi. I've posted about this and I haven't found a solution yet.

My GPU is at PCIe x8, rather than PCIe x16 and I'm trying to fix it.
I looked at the hardware, and it's definitely slotted into the x16 PCIe slot. Could it something else that's messing with this? Like a SATA device or something?
I do plan on getting a new GPU very soon, but for now I wanna make sure that nothing on my motherboard is defective.

I'm hoping it's something in my BIOS that could use tweaking or adjusting.

I've re-seated the GPU, cleaned the contacts with isotropic alcohol, nothing. I'm afraid something may be defective, and I'm hoping it isn't the motherboard because I wanna upgrade my GPU soon. I wanna say there's a setting in the BIOS (which I updated today) but there isn't anything in there.

Could it be my SATA setup?? Or perhaps that M.2 WD NAND SSD I have?

I really need help here.

My build:

CPU
Ryzen 7 3700X @ 3.6 Ghz

RAM
Corsair Vengeance LPX 16 Gb @ 3200 Mhz (XMP enabled)

Motherboard
AsRock Taichi X570

GPU
XFX Radeon R9 390X

Storage
931GB Western Digital WDC WD10EZRZ-00HTKB0 (SATA)
465GB Samsung SSD 850 EVO 500GB (SATA (SSD)
931GB Western Digital WDC WD10EZEX-00BN5A0 (SATA)
931GB Western Digital WDC WD10EZRZ-00HTKB0 (SATA)
465GB Western Digital WDC WDS500G2B0B (SATA (SSD)

Yeah I looked at this but I don't know what to configure/look at in my BIOS that would control those things.

I'm afraid that either my GPU or motherboard are defective. Please help me with this I'm so alone here.
