My Miner keeps restarting for no reason



As the title says I have a rig that used to work very stable, no issues no restarts at 188 MH/s. Now it just restarts for no reason, and it doesn’t give me a reason. I have other that usually restart because of watchdog but this one does’t give a reason at all. All I get is a notification on telegram saying rig booted. Any ideas why that is? What to do?

And secondly, the watchdog restart, I know turning down the OC works but any other ideas? Because before I started using HiveOS I was on windows, and since moving to HiveOS most rigs work a bit better than on windows, but the ones with watchdog error already work worse and I don’t want to keep turning them down to were I loose 10MH/s per rig because of turning down the OC. Most work for a few hours before they get 1 watchdog error, restart and work again for a few hours, so I guess it isn’t that big of a deal since their up time is really good, but I rather not have the error at all.
