Alright so quick update.
After a day of trying, I finally got a successful install of win 10.
Downloaded Doom and even woke up early to play before work.
A half hour in it crashed and restarted.
At work I realized I hadn't updated drivers. So I did that when I returned home. Played maybe and hour before my comp shut down.
Now... after letting it "cool" down. the (new) power button triggered no response. I flicked the PSU off and on then tried again.
Everything clicked on for about a second before turning back off.
If something's wrong I don't want to exacerbate it. But I'm at a total loss what it could be.
Halp?
Yeah I hope it's not something simple like bad ram. I did go for budget on that. Unfortunately it's that build is the only ddr4 capable machine, so there's really no way I can test them. I did try removing them one by one and switching docking ports to no avail.
Hopefully it'll all be finished by the end of this weekend. $30 to make the computer work is worth it IMO.
I did leave a note requesting that its doom2016 capable without any unexpected issues. Hopefully tech guy will come through on that.
