White pixel on screen

Hello Sumit,

I tried following your steps, however, the white pixel appeared again before I installed the display drivers. Also, no idea if this will help you but the white pixel is not there when I boot in safe mode. Any idea on what can be wrong?

 

Monitor is going black or distorted white randomly

I have a LCD monitor on my computer. Randomly, the monitor will either go completely black (as if powered off, and the power light turns off) or it will get a distorted frozen white screen (like how your smartphone would look if you dropped it in a toilet and tried to turn it on). Not too surprising, I have not dropped this 21 inch monitor in a toilet. The only way I can get the monitor to work again is by unplugging it and plugging it back in

I'm pretty sure that it is just a dead monitor that needs to be replaced, but a friend suggested that it might just be the power cord, since the monitor will work (like it is now) for hours on end, then suddenly start randomly not working. It's worth checking out, but before dropping money on a new monitor (if it isn't the power cord), can anyone confirm (or strongly suggest) that it is not a CPU issue or video card? Or maybe someone has seen this before?
