I have a Dell Optiplex 7450 AIO. I am getting a message saying, "The User Profile Service failed the sign-in. User profile cannot be loaded." I have Googled this and tried all suggestions. I have tried Restore PC. Got an error that it could not restore. I tried Resetting PC, that failed. I tried going to Safe Mode. The computer will not go to Safe Mode. It goes right back to Windows. I did diagnostics on the computer and All Tests Pass. Windows will load just fine. I just cannot login to the computer not even as Administrator. I took the hard drive out and attached to a different computer. Th

Dell AIO not posting

Hello, I am having problems with a certain PC. It is a Dell OptiPlex 7450 AIO non-touchscreen with a no-post problem. When it is powered on, the power light next to the power button will turn on and the DVD-RW drive will open, but the monitor will show
no signal and the hard drive LED will not turn on and I do not know why it happens, and I hope that there is a solution to this fix and I appreciate any responses, thanks!

 

The User Profile Service service failed the sign-in. User profile cannot be loaded.

Hello,

When attempting to login to my computer, I get the following message:

"The User Profile Service service failed the sign-in.

User profile cannot be loaded."

I referred to this Help article,You receive a "The User Profile Service failed the logon” error
message,

but the only difference is I only have one user profile on this computer. So, I can't login with another user to go through the steps listed in this post.

Any suggestions?

Thanks,

 

Dell Optiplex 9020 AIO screen is blank

You All-In-One is similar to a laptop with no dedicated video card. Your display adapter would be your Intel processor, not a dedicated Nvidia video card. You have not provided enough information to determine whether this is a hardware fault, a driver fault, or a DirectX or other OS issue. You might consider a USB-based monitor or USB docking station with a monitor to attempt to get a viewable screen while in Windows. This may give you more control or might be a usable permanent hardware workaround if you are unable to resolve the issue. Since you can get in through TeamViewer, I suggest you install the following updates to see if anything changes:

1. Dell Optiplex 9020 AIO BIOS update [dell.com]

2. Dell Optiplex 9020 AIO Intel 4xxx series display drivers [dell.com]

If your monitor works outside of Windows (proves the monitor itself is not dead), you might also consider resetting your BIOS settings to factory default. This may or may not occur with a BIOS update.
