Hey everyone! I purchased a second hand PO3-620-UR13 for my girlfriend that came with a GTX710 in it just to get it to boot. I tossed my old GTX970 in there and it worked great for a bit, but started getting graphical artifacts and weird bugs so I just got a good deal on an AMD RX6600 and threw it in and it will not boot. I’m getting a “one long-two short” repeating beep code. The PC boots and runs fine with the GTX710 slotted it, and i tested the RX6600 on my personal setup and it works fine. Any idea what the problem could be? Do these PCs lock out any GPU that isn’t Nvidia? I’m stumped, any help is appreciated. Thanks y’all!
