Windows 10 Freezes if I leave it for 20 minutes


I'm getting a very strange issue. I can work on my computer for many hours without any issues. But, if I step away for 20 minutes and come back, it's completely frozen and I have to hard reboot. To see if this is a problem with the sleep or hybrrid sleep functions, I disabled them all. Everything is set to NEVER shut off. But the freezing still happens if I walk away. Otherwise, no freezes.

So, what could be causing this freeze? Any idea?

 

Windows 10 freezes randomly

Try other SATA port and after the SATA cable.
For a month I was no longer a freeze. I have a track the heat, it's winter here. I will clean the pc and put some thermal paste back on the processor. This may also be a microsoft or nvidia update.When the pc freeze it takes 20 to 40 minutes to get a bsod. I waited a few times but without rating the bsod.
