My pc has been acting weird and slow, I oppened up settings and looked at my computer specs there. I found out I had 12 ram but only 3.97 of it usable, I opened the case and colocated the ram again in its places. I did that twice and when I boot up my pc it still shows me the same 12 installed ram but 3.97 usable. I wanted to see if anyone was willing to help! Thanks a lot!
