Hi there, I am at the end of my tether with this one, I wonder if anyone can help please? We bought a batch of 15 Vostro 15 3515s and I have 5 of them blue screening with DPC_WATCHDOG_VIOLATION.

I have tried rebuilding from a USB stick (no company image) to Windows 10 and Windows 11, updating all drivers and BIOS and they mostly blue screen within about 1/2 hour during a reboot to complete a driver update. Dell support sent an engineer for 2 of them, one was fixed with a motherboard and hard drive replacement, the same parts on the other one didn't fix it.

Does anyone have any ideas?

Thanks,

Chris
