A few months ago when I started playing the Witcher 3 my system would heat up to around 80 C and both my monitors would turn off and read "No signal" randomly. I eventually found out the thermal paste was faded so I removed and reapplied it and then downloaded MSI afterburner and haven't had an issue since. Today the "No signal" issue started again and I'm curious if maybe it was something else like my GPU or motherboard. Is there any troubleshooting I can do because I'd rather not re-reapply thermal paste.
