Last night when I was using the power was cut off suddenly. And this morning, I turned the PC on to find that some black bars had appeared on my desktop. It'slike, the screen is behind a prison bar. I thought it was because of viruses at first. But then after scanning the pc, I restarted the pc and those bars are still there. The thing is, when i pressed printscreen, and intended to paste into MS paint, no bars was on the image. 5 black bars, even when I'm posting this thread, those bars prevent the eyesight. So, it's because of my pc, viruses or anything else. Thanks for your help. now 3 have turned into white bars, one half white half the background colour of NF's Sasuke skin, and one the colour of my wallpaper. Then I unplugged the cable from the LCd display to the power, and the plugged it in again. I turned back to normal and then 5 white bars appeared again Somebody helps, pleae.
