Is my GPU a bust?
First, let me apologize if I use slightly wrong terminology. I'm not super technically inclined. So this entire post may be cope on my end, but I'm really hoping not. I Recently finished building my first PC a few days ago. Now. As I said, I'm not technically inclined but my friend is, and they helped me throughout this process. Despite this, there is one major problem left we haven't been able to solve.
So, after much struggle of buying the parts, replacing parts I thought would work with my build but didn't, and putting it all together, when I turned it on for the first time, I received a black screen with a white line. After checking this sub, I tried to reset the CMOS, I checked and double checked the wires and how everything was mounted. However, I could only get it to boot the BIOS to download my OS when I unplugged the GPU. Hoping that the problem would be resolved after I downloaded the OS, I do so. But, unfortunately, that did not solve the problem. If I leave the connection cables unplugged from the PSU, my computer runs perfectly. The moment I plug my GPU in, however, I get the black screen with a white line and the LED indicator that my motherboard comes with is telling me that a boot device is not detected.
My question is two parts: first, am I simply SoL and my GPU's simply broken? (A) If I'm not, what have I not tried to make it work? (B) if it is broken, where can I find a relatively cheap GPU that works and what, if anything, can I do with this GPU to recoup at least some of the cost? I won it in an ebay auction from a reputable seller that unfortunately doesn't accept returns, and such deals really don't come around often.
For reference, the GPU in question is a powercolor reaper Radeon RX 9070, my motherboard is an MSI B850M-VC with an integrated AMD Ryzen 7500X3D CPU, my PSU is a corsair SF 750 and I'm running Bazzite KDE.
ETA: Problem solved. Make sure to update your BIOS firmware kids, otherwise it might be a year out of date and your tech savvy friend has the legal right to laugh at you for the next forever.
