The problem was solved by Dell tech support.  The solution was to reinstall Windows from a stock Microsoft installer. I am an engineer myself and has dealt with customer/field issues.  In my opinion, this is clearly a software bug in one of the drivers that is triggered during hardware initialization.  Since the problem is not there when Windows was installed from a stock Microsoft installer, but was easily seen even after a factory reset (from the Dell image included on the SSD), the bug is likely to be in a Dell driver.  Before calling Dell support, I had already disabled and uninstalled most add-on software which I did not download myself and does not currently have on the laptop after the problem was solved (e.g. McAfee, Rivet, and an Intel audio driver).  I had kept SupportAssist.  There should be a documented bug for this problem.  But if there is, I am not aware of it.After the problem was solved by reinstalling Windows, I have reinstalled the latest BIOS from Dell.  But I have not installed any other package from Dell such as SupportAssist, because I am afraid the bug will be reintroduced.  I cleared the disk partition that held the Dell factory image, because a factory reset had not solved the problem, meaning that the bug was in that image.  That gave me 15G of addition disk space.  I kept the SupportAssist Diagnostics and OS Recovery images on the disk.  They can still be launched from BIOS.  The OS Recovery utility smartly omits the option to do a factory reset after failing to find the factory image. This had been a nasty problem as it did not occur on fast boot, which is the default for Windows 11.  Less savvy users may only notice it after some Windows updates that require a restart.
Hi,My new Inspiron laptop occasionally BSOD for a DPC Watchdog Violation upon restarts.  The cycling circle under the Dell logo will freeze, and after a couple of minutes, the BSOD is displayed. Once that occurs, it will usually repeat the same failure on automatic restarts until the Dell firmware offers to do OS Recovery.  But it seems the workaround is to power off the laptop and wait a while (e.g. 10 minutes), and power it back on again.  It will then boot normally.  It is running Windows 11. The model is an Inspiron 3525 (AMD Ryzen 3) with a 128G KIOXIA SSD.Could this be an indication of a defective SSD? Thanks!
