Couldn't get Memtest86+ to work, so I used the normal Memtest86. Didn't show any errors.

I also checked the virtual memory settings and it was set to automatic management.

Edit: Ran a small test. Opened Firefox and opened a Youtube video. Task manager showed 10 Processes and high energy/electricity usage before it crashed.
