After a Windows (automated) Update the problem is back... 1 (random) GPU drops hashrate after like 30 seconds the miner is running. sgminer and avermore both latestversion have the same problem.
Anyone an idea how solve this?
For me only a clean windows 10 (i guess ur using windows 10) by using an bootable usb stick fixed the problem.
I already test the next things what didnt solved the problem:
1. DDU for uinstalling all the AMD drivers, reinstalled with different versions of AMD (blockchain, 15.12, newest)
2. factory reset what is build inside the windows 10 options
3. disabled intel hd graphics
Only solution for me was to totally reinstall (so first format, install) windows 10.
Also firefox, chrome,opera can give u this errors/crashes/freezes since the big windows 10 update.
The new windows 10 update bricked my rig too. I did a reset, installed 18.5.1 drivers, and from now on i use StopUpdates10 to hopefully prevent the problem in the future.
It sucks to have to reset windows, but that worked for me! Other people i know had this problem too, hate Windows!
If you're blocking the Windows updates, you better only use this PC only for mining. If a new dangerous virus was released on the internet and Microsoft releases a safety update a few days later, you won't be able to get that update.
