After windows 8.1 upgrade, takes 5 minutes to restart

After upgrading a Dell XPS One using both Intel HD 4000 and nVidia 640M graphics, the computer takes 5 minutes to restart. The restart screen immediately shows up after hitting the restart button. Then the screen goes black for 5 minutes. Afterwards the Dell logo shows up and everything starts fine from there. I don't understand why the monitor stays black for 5 minutes before restarting.

Any suggestions are greatly appreciated.

If the harddrive is active during this time of black screen, you must wait, its busy, too busy to even display an image.
It may take a few boots for the problem to go away, but please avoid RESET, you can corrupt files it may be creating or rewriting.
If the prolem persists, try hitting (enter) two or three times during the black screen and see it progresses, again if the harddrive is flashing, its busy...
Busy could also mean having a hard time reading sectors, run scandisk for harddrive errors..

I had the exact same problem. After upgrading to 8.1 restart took over 2 minutes. For me the problem was Qualcomm Atheros Bluetooth suite 64. Since I don't use Bluetooth on my desktop I deleted it and now restart takes only a few seconds. There are many problems with the Qualcomm drivers and Windows 8.1. We're still waiting for a fix.

Hope this helps.

You might also try setting the system to use just the Intel graphics, if you can. Possibly a video driver is involved, there seems to have been some problems with those.

But Bluetooth has also been involved, as eanhalt1 mentions.

I now have the same issue, and I suspect it started after August Windows Updates, but I reboot so infrequently I'm not sure. Did you ever find an answer to the issue?

In my case, the monitor sleeps for about 90 seconds, and then presto, just like you, you see the BIOS logo and Windows boots normally. Normal time for that transition between boots would be about 2 seconds.

It's one of the weirder things I've seen, since it happens outside of Windows (as opposed to a slow-booting Windows issue, which is entirely different), but it's clearly caused by the prior Windows session, since I tried booting a WinRE that I have on USB, and reboots from it do not show the problem.

Win 8.1 x64 (since it came out, so not a recent install). Intel 3000 graphics only. No driver changes.

Update: Taking a cue from an earlier post about a BT driver, I recalled that I did update a wireless NIC driver. Once rolled back to the previous version of the driver (a nifty feature in Device Manager), the problem went away.

Unfortunately, I did the driver update right around the time of Windows Updates for August (though it didn't originate from there), which is how I was thrown so far off the scent.

How a Wifi driver (and in the other user's case, a BT driver) could possibly cause such a problem is beyond me.

In my case, it was a Ralink driver for the 802.11bgn 1T1R. The bad version is 5.1.11.1, while the good one is 5.1.7.0.
