all over plaid pattern on screen when restarted

[carylwithay]

After a power outage my computer was not quite right. When i restarted it there was a plaid like pattern in all shades of gray , black and white. When i put the pointer on it, the desktop came beck at each part I touched. i sort of was painting it back. I shut it down.
Any thoughts?
