I have installed this as my first Linux system about a month ago. When I run it for about an hour, it freezes.

Sometimes lasts longer like two full days, but just once.
It freezes when I freshly boot it up and let it sit, as a test.

I never ran it long enough for it to freeze on me while I'm using it, so I only know that it freezes when it is idle.

I went through a few funky processes to get the system running. I dual boot with windows 10. Once after setup, I decided I want to Linux partition to be bigger, so I used GParted to make it bigger.

This ended up corrupting the dual boot process, I forgot exactly how I fixed it but I think I ran the install disc, used it as the "try it" option and entered some command line.

Once the dual boot started working perfectly, I was comfortable enough that I could finally leave it alone for hours, so this is when I first started dealing with the freezes.

I have tried numerous things, like updating nvidia drivers, re-installing packages using command lines.

The freezing never stops. When it freezes, the entire machine is frozen. Hotkey to kill xserver will not work, or anything else.

My hardware:

• gtx 1070


• 16 gb ram


• i7 7700k


• Gigabyte GA-Z170X-UD3 Ultra motherboard

I installed using a disc. Should I try re-installing?
And try using a thumb drive?

Is this likely a hardware issue?
