Need help with my mining computer

Hey guys I have a been running my computer as a miner and everything worked fine the first couple days n now it shows my gpu (Radeon Rx 580 4gb) using zero gpu . Any idea what’s going on and what I can do to change this . To go into more detail it will say
accepted 031ccfdc diff 0.520/.500 gpu 0
accepted 0dh65vhy diff 1.150/0.500 gpu 0
So on n so forth. Is this due to sgminer and if so is there a way to use a different miner program ?

try Claymore’s miner for zcash

I’m using nicehash but it keeps using sgminer … it didn’t before but it switched to it now it won’t switch … it used xmrig at one point too
