I upgraded to Win 11 in November of 21. Things worked just fine. However, around Christmas I started having frequent crashes and loss for work. I did a clean reinstall in early January and had the same problems.. Finally, I did a clean install of Windows 10. I am having the same exact problems. There are no indications in the Event Viewer of what might be happening. There are crash dump files created.
I am now convinced that my 15 month old HP laptop is the problem. This does not happen with my 5 year old ASUS laptop with the same Windows 10 and software configurations.
As my HP warranty has expired, I'm working with the Costco Concierge support staff to see if we can get it replaced under the Costco extended warranty. It is not an easy process because they don't believe you.
