[NAME]   - System Restore shouldn't be taking hours.  I've had occasions where a Restore on my XPS 8930 also wouldn't finish.  In those cases, I force powered off, crossed my fingers, and rebooted.  At least for me, a message appeared up saying "Restore incomplete, system not changed". So everything was was before starting the Restore. YRMV... I also thought of that Realtek audio problem for your boot delays. But unless this has been going on for a rather long time, that may not be the issue.  Dell removed the problem Realtek audio driver v6.0.9025 more than a year ago and reposted v6.0.8248 from 2019 which is good.  Realtek audio driver v6.0.9107.1 is newer that .8248 and good too, but -for whatever reason- Dell didn't repost this one.  I'm running 9107.1 on my XPS 8930 and boot times are ~12 sec.  Check which version Realtek audio driver is installed on your PC when you get safely back to your desktop. And one more thingy...You don't want/need to make any changes in BIOS setup to change boot order.  Just plug a bootable USB into PC with power fully off, or insert bootable DVD into the drive and power PC fully off.  Then power on and tap F12 to open the boot menu. Select option to boot from USB (or from DVD) and PC will boot.
Hi, After installing a few new updates on my 8930 PC,  without warning or my trying to execute anything, my monitor turns to black and I get the message, in white letters, "EP_EXCEPTION SUB_HEADER" with a button underneath with "EP_EXCEPTION" displayed.   Not knowing what to do, I clicked on the button and the black and white screen went away and it turned all blue (the Dell color blue)  On the Task Bar line was a "Dell" circle that said "My Dell".  When I hit escape, it goes away.  It doesn't seem to affect anything, other than being annoying. I don't remember after which update I installed that this started happening. I don't like this and need help on how to remove it. Thanks. Jerry  
XPS 8930, what does EP_EXCEPTION SUB_HEADER mean?
