Dell Optiplex 790 hangs on Dell splash screen with USB microphone plugged in.
Hello,
We have several Dell Optiplex 790's that inconsistently hang on boot at the Dell splash screen. The load status bar goes all the way to full load and then just hangs. I have updated the BIOS to A16 and changed boot order but neither has helped. If we unplug the microphone and reboot , the system comes up fine. We then plug in the mic and it works fine. Then some time later when the PC reboots, it will hang again.
Has anyone else experienced this? The Mic is a

That was our initial thought. We have disabled the USB in boot options and set HD for first boot. We went as far as to disable all boot options other than HD. But we still have the issue.
Thanks for your reply.

It sounds like the system is attempting to boot from the USB device (MIC), which it can't, so it hangs.
Reboot (without MIC connected) and press F2 to open BIOS setup. Check the Boot Sequence (page 55) to make sure the hard drive is first and look for an option to turn off booting from USB. Be sure to save the changes before exiting setup

Hi SOUNDZ2GD1,
have you solved the problem?
I have the same issue with a USB token (a Giesecke & Devrient Starsign crypto usb token) / Optiplex 790 / Windows 7 32bits.
When it is plugged to an USB port, the computer does not restart. Only reboot is affected, cold boot always works fine.
At this situation, the computer hangs at DELL splash with boot progress bar at the middle.
Already tried to disable USB from boot options, last BIOS available is installed (A18) but didn't work.
Thanks

We did resolve the issue. We updated the BIOS, even if it showed 18 installed we ran the latest from Dell. Sometimes this still ran. Not sure if it was a different build or what, but worth checking. We also set boot from USB last in the boot order.
It sounds like you have tried all of these.
