Reboot it. If it does it at the bios screen then its ram has decided its the end
I went too the bios and it's fine.
I mean, its not SUPER noticeable, but the screen looks like it has mini pimples or measles. on and off, majority of the time on.
it only flickers when something is playing like a video or when i'm scrolling a page. but besides that, the dots stays in place.
this dell has the RGB LED 1920x1080 option! = super sexy vivid colors. but this problem is very annoying!!!
