Recently I noticed that if I changed my laptop's resolution to 640x480 it wont anything but some weird mostly green pixel stripes in the right side of the screen and some purple cubes on the left. I used CRU to create a custom resolution, then I used HRC to see if it fixes the issue, but when I changed the resolution with HRC to 640x480, those things mentioned above appeared again. I forced the laptop to shutdown with the power button, but when it turned on, the same issue appeared. I can only acess a menu with F12 on boot. I can't do anything now. I need fast help!
