As the title says, I cannot get my new build to post using the two GPU's I have available. When a gpu is not installed, my onboard graphics takes over just fine. but when any gpu is plugged in I get the fan pulsing and nothing further.
Goal: to not have to RMA or go to nvidia. Any help available would be generously appreciated.
specs:
used sapphire hd7950, and a like new but lightly used msi rx 570
850w power source, Gigabyte b460m ds3h, i5-10400,
32gb xpg spectrix ddr4, and an SSD w/ 2 day old windows install.
Background:
I've recently (<30 days) upgraded everything and the system was running well with the 7950, but with random crashes. adrenaline driver has always been up to date, with windows updated as well. 1st I learned the ram wasn't clocked right, and fixed that, which made the restarts go away for a while. But they returned when I began playing more intensive games. I bought an rx570 that needed it's bios updated which ran well for a few minutes before displaying the same crash and no post. I then upgraded the power supply and the same exact problems persist.
Troubleshooting:
Upgraded powersupply from 600 to 850 thinking it was a power issue.
Tested without gpu, computer does not appear to crash at all.
DDU amd and onboard intel drivers. - This worked the first time and allowed me to boot with the 570 plugged in. I began installing a december version of adrenaline that installed. I restart and began to change the screen scaling and it crashed again.
DDU again but both GPU's plugged in will cause a no post situation.
I've checked and updated all of my drivers.
I have not yet tried drinking the problem away, but am super close.
Thanks anyone,
