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 285

I'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 worked temporarily but would come back the next day. Now, it doesn't work for long at all). I thought the problem was conflicting programs on startup, but I've wiped everything.
  

I'm hoping this isn't a hardware problem. I don't have another computer to test my GPU on. If there is a way to fix this, please help me!

 

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)

PC hits black screen on boot, visual artifacts and freezing

Hi, so for the past week or so my PC has been having problems with random freezing and visual glitches/artifacts appearing on screen when I'm using it. Often it will happen when I'm watching a video, sometimes just a quick freeze/flicker but a few times the screen completely froze with lines everywhere, forcing me to do a hard shutdown.

Well, yesterday is when it went from bad to worse. I was watching a video and the screen and sound suddenly froze, and the screen went a strange brown colour with lines everywhere and I had to hard shutdown. When I booted back up, I encountered a black screen before I could even log on, and had to force shutdown again. Booted up again, same thing. After a third shutdown it began automatic repairs, and after trying to restart normally I once again encountered the black screen. So then I tried going into safe mode with networking and it let me log on as normal, except there were strange green lines everywhere, and on various apps after logging onto the desktop. These are always here now everytime I log on.

This is what it looks like when I restart in safe mode with networking:




A few things I've tried/ruled out:

• I've ran malware scans and nothing came up, so it doesn't look to be a virus
• I've tried using a spare monitor and the same problems came up, so it doesn't appear to be an issue with my monitor
• I've uninstalled my graphics drivers by going onto the device manager and hitting uninstall on my display adapter - after restarting, I'm able to boot up normally and log on at a lower resolution, but after a few minutes of being on the desktop the screen just goes black like before (perhaps because it's reinstalled the drivers?)

I'm running Windows 10 64-bit, version 1903 (OS Build 18362.476). Any help would be appreciated.
