Do drivers load even when related program has not been started?
Still trying to fix my win10 that BsODs frequently.
It seems to me that programs installed recently are the most likely problem, because of the drivers that come with the programs, which my system had not seen before, but the 3 programs installed in the 3 months before the BsOD problem started never get used (I used one or two of them once and they worked that first time.) One is Zoom, one is some special video player that seems related to some zoom-like setting, and the other one is nothing special. But if I don't start a program, could any bad drivers that came with it still cause a problem? Are drivers loaded at a startup, or any other time, even if the program isn't started? Unfortunately Uninstall Program does not work in safe mode, but I think I can get regular mode to work long enough to uninstall a few. |

The Windows Debugging Tools download I suggested in a previous post, it has windbg.exe, but it also has a tiny (21K) dumpchk.exe . And the dumpchk is supposed to decode .dmp files. Even the Reliability Monitor, if you hold your mouse over an item that represents a crash, it may present a balloon with the details of the crash. Roughly the equivalent of what dumpchk holds. https://www.tenforums.com/tutorials/...dows-10-a.html What I don't know, is if the 10.0.19041.1 version of dumpchk is actually recompiled for the latest Windows 10. It seems awfully small as Windows executables go. If I compile a program myself, it might be 96KB. Dumpchk being 21K or 22K, that's pretty small for a modern executable. ******* Drivers load at the time the kernel loads. In fast boot, the drivers are already loaded. An image of the kernel and drivers is restored, and the drivers are "warm started", to initialize the hardware registers associated with them. When your desktop appears after boot, all the drivers should be loaded. The driver has to initialize. It would define rings for memory buffers perhaps. It isn't so passive that its activities couldn't possibly have an effect. What it shouldn't be doing, is running when nobody is talking to it. A driver for a network device for example, it has to listen to arriving packets (Interrupt from NIC chip, service receive buffer ring), so it's not in a position to "snooze" and be innocuous. I would keep working on your "root cause", in the hopes of identifying what needs to be uninstalled. Instead of using the old "binary search" method (removing a bunch of stuff, seeing if it behaves better, remove a bunch more stuff and so on). Maybe a .dmp file admits to what is broken. Paul |
