Alright, so I hit up the chat earlier to find out why my computer was acting strangely and nothing helped besides rewinding back to a earlier point.
The problems I'm having are:
The brightness refuses to change
My video games are either laggy or do not start up at all
Videos rarely work, but they do
I have tried everything possible, and the only thing that worked temporarily was the rewind. What is going on? I need my computer for work and video games and this does not help me. The problem has persisted since yesterday.
