Black screen after upgrade from Windows 7 to Windows 10

I have installed windows 10 on a Dell Optiplex 7010. All went well until I got to the Login Screen, which appeared (the client does not have a password) and then went blank. After a while I could see the Windows 10 logo on bottom left of screen and I could access Ctrl+Alt+Delete but nothing more.

Is this a problem with the Graphics Card? Or is it something more  sinister?

other people's mileage may vary but my experience has been that this is usually one of 2 issues.  the first is what you suspect and it is a driver issue.
the other issue that I have seen that causes this behavior is that the user profile is corrupt.  if you can, update the drivers and see if that resolves the issue.  if not look around for how to reset the user profile.

Try to log on in safemode with the admin credentials, then go to the device manager to see if anything needs updating. If all drivers appear to be in good order, you could try to update the video drivers and the bios.  Then see if the user is able to on. If the problem exists as the user tries to log on as Sean mentions it could be a corrupted user profile.  If so create a new user profile for the user and transfer his files to the new user profile.  Or you can log on with admin credentials and then rename the corrupt profile to some thing else, ie just add an extra letter to his name. Then if the system is on the domain, have the user log in and the system will automatically create a new profile for the user. You can then give the user access the the old user files and transfer these files to the newly created profile.

you can do the following :
-disconnect all external devices
-restart a couple of times; and - if it shows no better screens, interrupt during the bootup by pulling the AC plug  ( for laptops- you need to remove the battery first) - this will give you the recovery options -  you can select the advanced options to work from there (install drivers etc..)

Black screen after login could be the display options. Right-click on desktop and personalize to change settings.

A Windows logo in a corner, suggests explorer loaded and start menu along with the taskbar are present, meaning explorer.exe is running.
If not, ctrl-alt-del taskmanager, run explorer.exe

Further to all the points raised above I am convinced this is a graphics problem. Given that I have the windows logo on bottom left of screen can i update the video drivers

It is unclear as was pointed out whether the update completed and you can get to the login promot after which you see a black screen with .....

One option, is to use ctrl-alt-del taskmanager or left ctrl-shift-ESC to get taskmanager running, run the task explorer and see whether you can get everything......

Do you have multiple displays that are assembled verticle versus horizontally?

Can not visualize what you mean by Windows logo in the corner.
I.e. Whether when the system booting up, the Windows logo is in the corner, or the start button is there but you can not do a thing.....

Bring up the task mgr and run a command prompt.  Then type in whoami.  I am leaning towards profilemissue personally

Thanks Arnold.  All installed smoothly until client had signed in and then I got the blank screen with the cursor, start button. I tried Task manager but nothing showed. I can right click on the desktop

Should I just reinstall”” Windows10

There are ways to create a new profile but likely you are going to have future issues.  Your overall best bet is to do a clean install
