I was playing around with an emulator and opened a few tabs in Google and suddenly my computer started slowing down. I knew this was because of my computer's weak processing power so I tried shutting down the emulator. Much to my dismay, my computer froze and then a second later it said changed to basic windows drivers. My resolution became way lower. I went to the control panel to change it back when I saw that 1600x900 (my monitor's resolution) wasn't an option. Is there any way to fix this? I'm currently on 1280 by 1024... it's not looking too good.
