Hey, I'm pretty new to Toms Hardware but I took out my GPU one day and switched for a better one on my AUROS B450 and now every time I try to boot my pc without resetting CMOS, 2 red lights flash from DRAM to CPU.
If you have 2 RAM sticks, boot with only 1 stick, go to BIOS and set DRAM to rated speed, if you get a POST after reboot, you can install the 2nd stick.
If it happens and you only have 1 RAM, you can reset CMOS and then do the same thing with DRAM speed.
This is worth a try, but it is going to be always useful to state your full specs along with the new GPU that you installed.
