What kind of GPUs? How many? What mobo, what PSU? You have to give us some more details to go on here. I've found that some systems you have to install the GPUS one at a time to get them all recognized.
My bad, I was frustrated and I should have included all the info.
I have 5 x RX570 4GB (4 are Asus and 1 is XFX) on a Asus TUF 270 A mobo with a cosair 850psu.
All
Asus GPUs are BIOs modded(undervolted/overclocked). the
XFX is stock BIOs until I can get this issue resolve then I will flash it also.
pulling 610 watts currently at the wall.
I did have my mining rig up and running for approximately 2 weeks with no issue until my PSU went out. I went and got the Cosair 850w.
I have today again used the DDU to uninstall the display drivers and restarted--installed the drivers back onto the cards--ran driver patch--restarted. When Rig comes back on it still have Error Code 43 in device manager.
all my windows update setting are turned off and this started happening when I have to change the original PSU.
If there is any other information that may help, I will send it as soon as I see it on here.
I have not tried to reinstall windows back on the Rig, but I will reinstall windows after work today and then reinstall the drivers to see if that works. thanks again for the help or suggestions. I have been googling and youtubing for 3 days now and feel like im in a loop
