PC is freezing when I'm playing games and watching stream on side (dual monitor). Never happened in the past 5 years.

Hey there.

In the past 3 days, I've been running into an issue where both of my monitors' screens freeze. Nothing can be done besides pressing the reset button on my PC. This happens when I'm playing games and watching a stream on the side. I've never run into this issue in all my years of gaming, plus I've upgraded some parts (CPU, GFX, SSD). This has happened for the games: Total War: Warhammer 2 and CS:GO. On the side, I'm running a stream (twitch - 480p, nba stream - 720p).

Coincidentally, this has happened after I updated my Windows 10 with the Fall Creator Update. I don't know if it has anything to do with that.

Solutions I've tried: Cleaning the dust inside my PC, reinstalling graphics card.

Here are the attached documents that include:

DXDiag, HWMonitor before and after. My PSU is 550W.

Edit: Just found out that there are no attachment functions on this forum. Posting gyazos.

Here's something interesting I found in Task Manager while running the game and stream:

Don't know what the Desktop Window Manager is, but it's eating up so much RAM. I have all visual performance options set to maximum performance, disabled most background services.

Update: Just ran a memtest86 for 6 hours. I had no errors and passed all 4 tests.

Try this:
- Download DDU
- Boot in Safe Mode, start DDU
- If you have Geforce Experience/AMD Catalist(or Crimson something), uninstall them
- Uninstall any graphics driver
- Do a normal boot (with internet connection) and wait untill Windows automatically installs your GPUs driver. Then try and do some gaming, benchmarks, whatever.
