Windows 8 Pro x64 - BSOD with Driver Verifier

Hi all,

This is my first post. Please excuse any failings therefore.

Recently, over the last three days, I have been experiencing random BSOD's, atleast once a day. I have not added any new hardware or any new software that I am aware of apart from Windows Updates. I an running Driver Verifier and it crashed on startup today morning. I believe all the crashes came quickly after startup.

Your help would be much appreciated. I looked at the dumps and they seem to indicate USB but I am not sure since the cause changes each time.

SF Diagnostics attached! Thanks

Any help?

Thanks

Just got another crash... it is highlighting dot4usb.sys. Any ideas? I believe it is the HP driver. I have a printer/scanner attached via USB to the the computer and a wireless laserjet printer with drivers installed

So this does seem to happen when the PC has been sleeping for some time and is waking up back again. Please help with your thoughts
