Alright folks, I am in need of a small bit of help.

Scenario:

I thought I had reverted bios to stock on AMD 580s so that I could tune in GGS. Wrong.

After I select "boost" I saw a pixelated screen and windows locked up. I rebooted, uninstalled GGS, deleted files in appdata folder left behind after uninstall, re-ran and reinstalled.  GGS came up and I selected "restore" settings just in case it took off mining with the boosted settings again.

It ran fine for 15-20 minutes and then one card went to 0, then the other. This is my gaming PC, not my rig.

After a reboot, windows squaked that it could not read the memory at location: 0x000000000[whatever]:[whatever] which was happening when windows first tried to re-install the GPU driver. Upon second reboot, same message, no driver install. On third reboot, no message, no driver, cannot start radeon settings program.

I took one of the cards out and swapped it into my rig where it has run fine for over 4 hours.

However, back on the gaming PC, windows will now not recognize any video card, not AMD nor NVIDIA and resorts to a default driver.

I have run DDU for both AMD and NVIDIA drivers from safe mode twice.

Request:

1) What do I do with windows in this state? Spidey senses are signalling a reset and loss of installed programs thus time spent in search of license keys and documentation prior to a reset/reinstall.

2) Where do I find stock a reliable list of stock BIOSes? I've got several tools which allow me to see manufacturer information (cpu-z for instance) and SRBPolaris to check memory supplier.

Comment on issue with GGS: when running 13 cards, the AMD cards(4) come and go in productivity but Nvidia(9) cards all function fine.

Thank you in advance for any assistance given,

Hank
