My PC, there is something wrong with it.





This happened yesterday as well.I was using my PC, and out of nowhere the screen went black. After about a minute, it came back, but everything was enlarged. I was O__o. Then, it went black again a couple of times, and it was back to normal.

Today, I logged on and it was normal. But after about 30 secs it went back to this..

What happen and how do I fix this.
