Frequent crashes

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.

   Warning

Programs that claim to update your drivers install either the wrong or corrupted drivers.
If you have installed any driver with Drivertoolkit, please remove them as it may cause trouble.

The crash, the only one that has been saved, is caused by an outdated driver of 1 of your audio devices.
If updating is possible, try it, else you should remove it.

You can't upload .dmp files directly because they aren't supported, this is a reason why a BSOD Posting Instructions topic has been created.

IObit is causing the crash, not really a surprise to me because IObit software is known for causing problems.
My recommendation is to get rid of IObit software.
