Is the RAM 1x16 GB or 2x 8 GB? If 2x 8 GB, remove the module from 4th slot from CPU and test with just one in 2nd slot. If that worksw without freezes, swap the other one into 2nd slot and test... Where are you seeing "Pointer 41" errors? Is that in Windows Event Viewer or somewhere else? Try uninstalling SupportAssist completely using Revo Uninstaller (free) and see what happens after it's totally gone. When Revo shows screens with "leftovers" marked in bold, delete all of them but nothing else, especially nothing shown in red. When Revo is done, reboot and test...
Windows 11 Home 21H2: Long story short: our old XPS 8920 was unusable due to constant desktop freezes. Eventually determined to be a motherboard failure. Out of warranty.Just recently (October 25, 2021) bought a refurbished XPS 8940 with a 13 month warranty. Wouldn't you know it, I've also had several BSOD/Reference by Pointer 41 errors. But don't know whether that's related or a different problem. The biggest issue is a freezing desktop: the active application/window will always function normally but everything in the background is unresponsive. The only way to regain control of the desktop is via Ctrl+Alt+Del/Task Manager, at which point it 'wakes up'. This happens dozens of times/day, rendering the computer basically useless. I've tried sfc/dism scans, mem tests, updated all drivers manually (since Dell Support Assist causes BSOD), updated BIOS, hardware diagnostics, updating and reinstalling Windows. Nothing makes any difference. If anyone out there has any suggestions I'd be eternally grateful.
