Seemingly Random BSODs

Did you unplug external USB device before restarting your computer

Will think of more causes later

I'm not sure about this, but would you be willing to un-install that "syncs frash drive" just for testing. The dump file not always true 100%, therefore within my ability, I can't give you more exact information. Also, it never hurt to try and you can always re-install it if it's not the problem

I did ask for help from great experts in this forum, will keep you in touch

Hi AlBeshweegee
The minidump file that you just posted gave me same result. I don't think it's hardware problem. The bugcheck indicated usbport.sys, which is system file. I guess that the usb driver usbport.sys is conflicting, damaged, or that something is connected to the usbport is not happy
That driver is the default window driver for usbport. I would suggest to reload all the usb driver for usb devices
To do that: in the device manager (computer-->manage-->device manager), remove the listing in usb section (right click-->uninstall), and then restart your machine

I hope the problem will go away

here is the bugcheck:

What devices are hooked up via USB?

Yep, I would re-install them all with reventon's suggestion for the NEC USB3
Good Luck
