Windows 10: Pc keeps crashing with pixels appearing

Hi! Just today started having this issue. My pc started just today crashing whenever i launch a game. It might take 10minutes or 15seconds. Everytime this happens i get pixels appearing allover my screen and sometimes my whole computer just freezes. I thought right away that this was because of my gpu, so i swapped gpus with my brother to see if its the gpu. After switching the gpu the crashing stopped but i had these blue pixels allover my screen if there was a dark backround. Now I am not sure if the problem is still the gpu or something else.I have a i5-8600k and gtx 1060 strix. Can anyone

:)

 

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.
Before:



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.

dead pixels, every app crashes

I suggest take it to the retailer for proper assessment as soon as possible.

There are several troubleshooting steps for the instability issues (suspecting a faulty SD memory card) but the phone need official evaluation of the dead pixels.

all games crash!

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?
