Ah, I see. Is there any way I would be able to test the PSU? I 100% understand the touchiness of compatibility issues, even when building an all current gen set up. This particular MB and CPU combo is great, but gets wonky when upgrading. For examply, if I upgrade the CPU to 3rd gen i5 or better I'll have to update BIOS and flashing this MB BIOS is a toss up at best. I didn't try to get into the BIOS but the ASRock splash screen does show with the 2070. Which makes me think the PSU is ok, otherwise it wouldn't send any picture right?
Is there any way I could replace the MB and the CPU but retain my recently purchased DDR3 ram and GPU? I really don't want to spend another $1k when I just spent $800 between the monitor and GPU.
I rue the day I bought an ASRock MB.
Thanks doomsriker for all the info. I know it's a tricky thing to diagnose, especially remotely, with decade old parts. lol
Thanks for the insight DoctorNick, I'll bump it up to 4.8ghz if I can get this GPU to boot properly.
