I have been having problems recently with PC crashes and lockups, sometimes with weird screens with unique characters and just blank yellowish screens. I then seemed to fix the problem by turning off power saving mode on my monitor, but the problem had been inconsistent with the crashes so I'm still not sure. I then tried playing some "Hitman: Absolution" but it crashed with bug that some people have, but that wasn't the problem. The problem was that it said I was only using two gigabytes of my eight (two four gigs). I upgraded BIOS and it said that it was using four gigs, so I thought I would find which stick was the problem and replace it as soon as possible. But the next morning it was back to two! So I thought I would make an account on here to see what you guys had to say. I also will link to a picture of what my System Info. section says about my RAM.
Help would be much appreciated!
