Mouse and keyboard are being automatically switched off and computer showing weird graphics
I am using Ubuntu 12.04. I've observed following symptoms from yesterday,
Suddenly my mouse and keyboard are switched off(Indicator lights are also off, and unplugging and plugging also doesn’t help).
SSH is working when above condition is observed.
My computer display is showing some weird graphics(lines and different colors). Graphics are restored after sometime when I pressed tty shortcut CTRL+ALT+F6 and CTRL+ALT+F7.(I tried them because I just wanted to restart my computer by logging in to another tty )
Sometimes my computer is showing black screen with some data(which generally comes during shutdown of any Ubuntu computer). After sometime display graphics are showing weird graphics as described above.
While booting my computer says something about memory and press F1 to continue. Although I've made no hardware component changes recently.
