Fix most crashes

This fixed my crashes in AC Valhalla. I got this information from Ubisoft Support and Microsoft's site. Let me know if it works for you!

Step 1: Clean Boot Windows

A clean boot starts Windows with only Microsoft services. Here's a guide on Microsoft's website on how to do it

You may need to enable some services that aren't Microsoft's but are essential for your computer like Nvidia's containers and Realtek audio.

Step 2: Play the game to see if it crashes

After performing a clean boot, play the game to see if it crashes like before. If you can play for longer than you did before without a crashes, chances are one of the services disabled by the clean boot is the problem.

If the game does crash, make sure you really did perform a clean boot by following step 1, if you did and it still crashes, this guide may not help.

Step 3: Enable services until you crash again

If during step 2 you found that the game doesn't crash, you now need to start enabling non-Microsoft services until the game crashes again.

I find it best to enable about 5 services at a time so you're not just going 1 by 1, but also don't enable so many that it's hard to narrow it down.

Go through the clean boot process again, but this time do the following:

a. Click the Services tab, click Disable all, select the check box for the first five services listed then restart the computer. If the problem does not occur then you can eliminate those five services as the cause of the problem.
b. With the first five services selected, select the second five services check boxes, then restart the computer.
c. Repeat this process until you reproduce the crash. If you cannot reproduce the crash then you can eliminate system services as the cause of the problem. Go to next step in guide.

Step 4: Identify the startup item causing the crash

In the msconfig tool:

a. Click the General tab, and select the Load startup items check box.
b. Click the Startup tab, click Disable all, select the check box for the first startup item that is listed then restart the computer. If the crash does not occur then you can eliminate the first startup item as the cause of the crash.
c. With the first startup item selected, select the second startup item check box and restart the computer. Repeat this process until you reproduce the crash.

For me, rolling back my Nvidia driver to 532.03 worked wonders. Ive not crashed now in 20 hours probably. I was crashing about every 4 hours awhile ago.
From what I have gathered from this forum, most of the crashes to desktop ive heard about are when using Nvidia GPUs. Has anyone with an AMD crashed to desktop frequently?
