Windows 10: Monitor goes no signal randomly + screen frozen which dots/pixels start appearing on the...

I have been having this problem for a month now and it is still not resolved yet. Basically the video shows a monitor that has probably stopped working somehow I mean I'm tryna say that the screen has no response, I tapped on some keys in the keyboard and clicking the mouse, as well as moving the mouse and still no response, and you'll be seeing random dots or pixels in the screen that are colored red. This occurs for probably 10-30 minutes and I've been tryna fix this problem since the first place, and I even let my Father help me fix this issue. I replaced the power supply unit, the thermal

Second monitor appears pixelated sometimes

Before we get started, here might be some setup information that may be worth noting. My primary monitor is a 1080p, 1920 x 1080 (native) using an HDMI to DVI. My secondary monitor is a SONY TV 1360 x 768 (native) using an HDMI. Both are connected to my graphics card and not the motherboard. I have always had this setup but I have not always had this issue.

Preforming the following actions may cause my second monitor to appear pixelated.

• Getting a web browser out of maximized mode by click dragging the window or using the restore button
• Using full screen on the secondary monitor
• Dragging a window into the second monitor, sometimes

In order to temporarily solve this issue I must apply a change to any display using the Nvidia Control Panel. Using the Windows display settings to apply a change does not always fix the issue. Also note that after the second monitor goes pixelated, my computer does not detect a change in any display's resolution settings.

So far I have tried the following fixes to no avail

• Keeping display drivers up to date
• Using a DDU to wipe display drivers clean and start anew
• Using the Hardware and Devices troubleshooter

I have tried to use capture software to screenshot the pixelation but it can not see it. I have to use a camera to show what it looks like instead.

Capture software is not capable of detecting the pixelation so I have recreated what it looks like on screen. Use this as reverence if the pictures look bad.

Screen pixelating randomly

My computer sometimes shuts down randomly, and the screen goes black with white and colored pixels scattered around the display. I have no choice but to turn it off with the button and then turn it back on.

 

Dotted 1 pixel wide line vertically on screen.

I'm asking here as i am pretty sure this is a software problem as when i move my mouse over it the pixels change colour and therefore are not dead. The pixels themselves are dotted blue and black 1 pixel wide vertically in a line down my screen. I first
noticed it a month or so ago but it went away after a few hours. Since the it has kept randomly appearing and disappearing when i use my computer. It may be useful to note that it seems to be in the location where i usually have the border of one of my windows.
(i usually have 2 windows open at once and the border between those two windows seems to be where the line is drawn) this may be especially interesting as recently i moved the window border slightly and the next time the line showed up it appeared in that
new place. This could all be a red herring however. I would very much like to hear from someone who may be able to help as it is very unusual and distracting.

Other potentially important things to note:

I use 2 monitors

I use a nvidia 1050 Ti graphics card

The monitors i use are Samsung C24F390 24 inch curved screen monitors.

Any help would be greatly appreciated.
