Windows 10: Windows 10 screen freezes and pixels start appearing in display monitor loses signal...

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 g

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.

After:




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.

PC Freeze and No Signal to Monitor

Hi, I recently built a pc and I'm using Windows 10 21H2 19044.1766. So to explain the problem, the computer freezed yesterday, the keyboard and mouse changed nothing on the screen. But I could still see the everything, no error appeared. Then I restarted the computer by the reset button on the case. Today, it happened again. This time, I tried to restart the monitor. It said no signal on the display while the computer fans were still runnning. What may be the cause for this and how can I fix it? Any help is appreciated.

 

GTX 1050 ti Monitors Lose Signal

So far there's been a catalogue of symptoms, and the worrying thing is there are literally pages and pages of the same issue with GTX 1050's on the GeForce forums.

Symptoms so far:

• After getting to the logon screen, both my 4K monitor (plugged in via DP) and my 1080p monitor (plugged in via HDMI) spuriously lose signal for ~5 seconds then come back. This happens constantly with no apparent timing.

• Whenever I open a game launcher (not a game), or Google Chrome, the screen flickers again, only this time I get a Windows 10 event alert saying "application has been blocked from accessing graphics hardware".

• When I check event viewer System logs, the yellow triangle simply says "nvlddmkm stopped responding" in each case of the monitors losing signal.

Attempted fixes from numerous threads:

• Installed the latest Game Ready "stable" drivers, installed latest "beta" drivers, and also installed some random "stable" drivers from a month ago. Uninstalled previous drivers with DDU each time and restarted before and after installation. Issue seems to persist sporadically.
• Turned PCI Power Management off in Windows Power Settings. No change.
• Switched Power settings in NVidia Control Panel to Maximum Performance. No change.
• Gone into the registry and added a QWord(64bit) to CurrentControlSet001/Graphics/Drivers called "TdrDelay" and set it to 8 (also tried 10). No change.
• Tried unplugging the secondary monitor. Managed to play Warframe for an entire evening without a monitor signal loss.
• Switched secondary monitor to DVI Single Link cable to 1050 ti, and also tried secondary monitor on iGPU with primary monitor on 1050 ti. Still get signal losses on main monitor, secondary monitor does the same but is delayed (WTF?).
• Downclocked GPU 50Mhz. No change.
• Increased Power Limit by 5%. No change.

Fixes I still need to try:

• Try a different DP cable in main monitor/try HDMI cable instead.
  
• I get the signal loss when I open Chrome, going to turn off hardware acceleration as that apparently solves things
• Use a DWord(32bit) registry key instead of QWord for TdrDelay
• Going to try the 375.50 drivers, as they're allegedly old but stable for low power Pascal GPUs.
• Resetting CMOS for whatever reasons - some random guy said this solved his issues.

Fairly convinced it's not a hardware issue since there are so many people with the same issue as me. One slight glimmer of explanation is that Micron memory may be at fault, I need to check if its Samsung or Micron stuff on mine. Apparently there were some GTX 1070 stability issues with Micron VRAM that were fixed with an update.

My entire system has been stable for years, sporting a R9 295x2 up until 6 months ago with no stability problems. Doubt it's PSU related. Motherboard is also on the latest 2.50 BIOS.

Help me TPU, you're my only hope.
