I recently updated my PC to the 25H2 version of Windows 11, but during the update, it crashed to a blue screen of death (BSOD) multiple times. The crash dump files and error codes indicated a memory issue. After testing both my RAM and SSDs, I found no faults. However, now my PC BSODs every few minutes, even on the desktop.
I've attempted to do a clean install of Windows 11, but it fails around 75% of the way through every time. I've tried both of my SSDs, but it doesn't help. The error I get is "Stop code: SYSTEM_SERVICE_EXCEPTION (0x3B)" and it mentions that "FLTMGR.SYS" failed. Here's my setup:
- **CPU**: Intel i9-14900k
- **Motherboard**: MSI Tomahawk Z790 Tomahawk Max WiFi
- **RAM**: Corsair Dominator Titanium RGB DDR5 64GB (2x32GB) at 6000MHz
- **SSDs**: Samsung 990 Pro (1TB and 4TB)
- **PSU**: Corsair RM1200x Shift
- **GPU**: RTX 4090 (not currently in use)

It sounds like you're having a frustrating time with that update and clean install. First things first—if you can access Windows in any way or even boot into Safe Mode, check for any dump files in the C:WindowsMinidump folder. Those files can give insight into what's causing the BSODs. You can compress that folder and share it with someone for analysis! If you don't have any dump files, you might want to adjust the settings to create small memory dumps next time your system crashes, so you have something to work with if it happens again.
Have you run a memory test with Memtest86 yet? That's usually a solid starting point. If it reveals any errors, try disabling the XMP profile and testing again. Additionally, you might want to lower the performance core ratio as a sanity check. If you're still getting BSODs, consider trying a different OS, like Windows 10 or even a Linux distribution—Linux can really help isolate the error you're facing.
Honestly, a lot of users are feeling like Windows 11 is turning into malware with some of the updates. My advice? If you can hold off on updates for a little while, do it—especially until you see others confirming that it's safe. No one wants to deal with endless BSODs!
