I upgraded my PC about 2-3 months ago and have had no issues with it since i got it to first boot. When i press the power button the ram and cpu error lights come on my motherboard for 30 seconds - a minute and then turn off. I had a similar issue when i built it and it was a problem with a gen 3 riser cable connecting a gen 5 slot to a gen 4 card. I got it working by unplugging the gpu and booting off intergrated graphics and then switching the pcie generation to 3. However now when i try and do this i am still unable to boot into the bios. I am running a ryzen 5 7600x, 2x16gb ddr5, msi b650i edge wifi, rtx 3060 and 2x HDPlex 250w passive psu’s. Any advice would go a long way :)
