Windows 10: Screen Artifacts and Crashing

The problem: Screen artifacts occur randomly. Artifacts usually get worse before my screen freezes, blacks out, and comes back on. This repeats until it crashes. Once, I got a blue screen with the error code "Memory Management". Details: I have two monitors and they are behaving the same. This is a desktop computer. The screen behaves correctly in safe mode. GPU: NVIDIA GeForce GTX 285I've tried: Updating graphics driver twice. Used DDU the second time. Scanning for malware twice. I've since wiped all files. Checked wires.Dusted computer. Checked fans. Disabled startup programs This worke

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Step-by step overclocking in Wattman

What causes these odd font artifacts around numbers

The artifacts you are seeing appear only with numbers, but that's a red herring. It's a screen artifact like any other screen artifact that sometimes affects a monitor. The problem is that these artifacts have a million causes, give or take.

Presuming that you have a graphics driver that is supported on Windows 10, and that you have already tried restarting your computer, here are some fixes that have worked for others:

• Refresh the screen (press F5.) You may have to do this 2 or 3 times.
• Turn off ClearType.
• Open Task Manager and End Task on Windows Explorer. That forces the Windows shell to restart.

 

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?
