Windows updates trigger reboots and lead to boot issues or endless memory training problems.
Windows updates trigger reboots and lead to boot issues or endless memory training problems.
Hi, my issue is a bit weird and complicated as it manifests in different ways, so sorry if this is some parts are unclear ! I'm having a few different issues on my PC, mostly on reboots. I think they're all linked in some way, but I can't put my finger on the exact cause. Here are the symptoms : every time I start a windows update, the reboot fails : the PC shuts down, then starts again but gets stuck in what I assume is memory training (DRAM LED is on and nothing happens) but never completes, even after a forced reboot. To get out of this, I have to : 1) force shutdown the pc 2) remove one of my two RAM sticks 3) reboot, I get a "Boot failure detected" message 4) enter BIOS, don't change anything, save and shutdown 5) put the second stick back in 6) reboot, enter bios, save and reboot, windows finally starts. This issue also can happen on "normal" reboots, but so far only update-triggered reboots have been 100% reliable in causing it. Sometimes, but it's become rarer these last weeks, I just get a "boot failure detected" out of the blue. I just have to enter the bios, change nothing, save and exit and it starts fine. Sometimes after a reboot, my fans (both CPU and case, all are directly wired to the MB) start spinning at full speed, even though fan curves are set in the BIOS. Since I use FanControl they go back to acceptable speeds once windows starts, but the entire startup phase is quite loud At some point I also had a few BSODs, either VIDEO_SCHEDULER_INTERNAL_ERROR or PAGE_FAULT_IN_NONPAGED_AREA, unfortunately I don't have the minidumps anymore, though I didn't get any recently so yay ? Sometimes after booting in Windows, I get a few graphical glitches : green bands on the login screen, then everything is really laggy (mouse movement, video playback...) on my main display. Restarting fixes everything, not able to reproduce reliably, didn't happen recently so might have been fixed by a driver update ? Here's what I know : The issue(s) all started to arise in early January, except for the fans thing, this one's been here for longer I might have updated my BIOS not long before that time, but I'm not sure when exactly. I did update it again multiple times since and the boot issues are still present. Around the time it all started, I had to install/remove lots of Python packages, I can't realy see that being related but it's the only "major" system change that happened then. Here are my specs , including two recent minidumps. PC was built in July of last year. There is a CO offset of -30 on every core for thermals and power consumption. RAM is Corsair Vengeance 6000MT/s with EXPO enabled. Here's what I tried : Obviously I went through the "classic" sfc/DISM/chkdsk in Windows, there were either no issues or they were fixed, running again shows no error Updated my drivers (multiple times for the GPU) as well as BIOS Ran Memtest86+ for almost 24h, it did around 15 passes of all tests, nothing Ran folding@home over night to stress the system (CPU and GPU), it didn't crash or error out Did multiple AV scans, both in Windows and from a live USB, nothing was found Checked my performance both in games and benchmarks, seems fine compared to "before" Ran memtest64 as well as Prime95 large FFTs to test the RAM with a load on the rest of the system, nothing With all of this, I'm leaning towards a motherboard issue or maybe RAM, but I'm really not sure so I'd like some advice before sending anything back under warranty. Thanks for your help !
I’d attempt to remove the latest update via advanced troubleshooting. However, since you’ve already taken some steps, I’d probably just reinstall from scratch.
