Area-51 R2, freezing and restarting

​ Hello, ​

​ ​

​ I've been having some strange and pretty consistent issues with my Alienware Area-51 R2. ​

​ The first issue is that while gaming it will completely lock up. I can't move the mouse, type, hit ctrl+alt+del, or anything else. However, I can still hear audio and continue talking if I'm Discord. ​

​ ​

​ The second issue is that the computer will randomly restart itself out of nowhere. This happens when I'm using it and when it is sitting idle. ​

​ ​

​ I initially thought this was a graphics card problem. I've got 2 GTX1070s. I've tried using SLI and using each one separately but that didn't work. I've recently replaced the SSD, but these issues were happening before this. No problems show up on hardware and software scans. I'm kind of stuck. ​
