My computer is doing some odd things the last week, I need your help if you know what this may be.
It doesn't happen all the time, but at some point while on for a while the screen will flash off and on. The screen will become messed up: things missing, blank windows, and such. Usually I can get it to shut down if I click in between flashing screens. Sometimes I have to unplug the tower.
I ran anti-virus software but the flashing will start before the scan can finish. I also noticed that when the computer boots up. Some of the DOS characters will be a different color (ie. a purple "f" on a black and white screen. I noticed in the set up that some words were misspelled. Here is one example to the right.
I recorded the flashing with my phone to show what i see once it starts. this has never happened to me before. But I do remember what I was doing when it first started. I was editing the Closed Caption to a video on YouTube. It started when I shared info with YouTube from the editing software.
So I'm not sure if it is
- a virus
- bad monitor
- video driver problem
- compatibility issue
Any help would be greatly appreciated.
Here is the video of the flashing monitor.
