So, I have this one R9 280 which was in family PC, in idle it often crashed, freezed and restart was needed. I swapped gpu for GTX 1650 and we did not run into any problems So as I had spare old hardware I built my sister computer with that R9 280 and again, crashes in idle, but this time it corrupted Windows 10, luckly I fixed that but what can be cause of that? Under load gpu, games and stress tests, is totaly fine, never crashed, I tried old and new drivers but no success. The only thing that I can think of is to flash new bios but I cant find one for HIS R9 280 IceQ OC (blower style), only for dual fan style gpu.
