Programs that claim to update your drivers install either the wrong or corrupted drivers.
If you have installed any driver with SlimDrivers, please remove them as it may cause trouble.
You can try to remove the installed drivers via a system restore point prior SlimDrivers.
If you are using a program like Ccleaner please stop using it while troubleshooting.
This because programs like Ccleaner remove dump files that are needed to troubleshoot.
Or configure Ccleaner to not remove dump files:
Please remove / disable items from the startup in taskmanager
These programs could interfere with the boot process giving you trouble and increase the boot time.
It seems the crashes are caused by a driver called Accelerometer, it looks like it is used by Dell software but it may be something else too.
Please remove Dell software and report back how your system behaves
