Ubuntu crash help, please?
One of the computers in my house was awfully slow, so I installed Ubuntu to speed it up and add stability. (Yes, I could have just added more RAM. But that wouldn't be free, would it?) Being my first time using Ubuntu, I was really surprised at how much I could push the processor without running out of memory. However,I still have one problem, which seems to be occurring every three days, or so.
Spontaneously, the screen turns black for a few seconds, then flashes white, vertical, one-inch wide bars at one-second intervals.
I've searched everywhere on the internet, yet I don't even know what the white bars mean. Does anyone know what the bars are, maybe what the cause is, and how I might go about fixing it?
