I was mining with claymore 9.8 & 1 card NVIDIA 1060 and I did some OC with msi afterburner, I was getting BSOD & freezing on windows 2-3 times a day, recently I had bought 2 XFX 580 4G & start mining with Claymore 10.2 using the command -tt 69,69,0(0 for NVIDIA), I lowered the OC of the gtx 1060 but i was still getting freezing in windows but no more BSOD, until yesterday the rig mined all the night without any problem then in the day the rig crashed on windows and the fan of the cards stopped and i smelled burning smell coming out from one of the XFX 580, i restarted the pc & I found that the card can be detected with gpu-z but when i start Claymore i got BSOD so the card is dead, now i am afraid that the same think will happen to the other cards, so I am looking for help to avoid that problem will happen again.
i was using "-dcri 30,30,38 -ftime 10 -cclock 1100,1100,0 -mclock 2045,2035,0 -cvddc 900,900,0 -mvddc 900,900,0 -tt 69,69,0" i got eth +decri 29,29,21 & 875,875,274.

Try to lower your clocks, and adjust your -tt to at least 75, are you using risers? the burn smell could be your riser as the AMD rx580 is a power hungry unlike the GTX, check your cables from riser to PSU, probably there burnt connectors out there.
Hows your device manager settings? are they in normal without any errors? I would suggest to do the test one by one, exclude nvidia first and let the AMD to be installed and do the mining. this is to isolate what may be the culprits. riser may look fine but in a while they seem to be faulty try to replace them if you have any extras.
