Okay so earlier my mouse started to freeze up while playing DOTA 2. It would move sideways but would be hesitant to move upwards. I restarted my computer and it was still like that however a few of my steam games, including dota, were uninstalled for some reason. After that I restarted again and my mouse / monitor wouldn't turn on. I did some research and people were recommending I remove the ram closest to the CPU, which I did, and my computer turned on again but it was still doing the mouse shit. After that I restarted and it was the same old shit, no monitor or mouse turning on. I tried putting the ram in different slots and everything. Finally I went back to the original setup of having both of my ram in the blue slots on my motherboard. That didn't work, obviously, so I again removed my RAM closest to the CPU because it worked earlier. The computer is currently on but the mouse is still hesitant to work. I'm thinking it has to be a motherboard problem or a PSU problem but I'm not too technical with computers past being able to put one together. Any help is greatly appreciated, thanks.
