Hi all

I have an ASUS P7H55M/USB 3 MB with i5 CPU 4Gig RAM NVIDEA 210 graphics card with latest drivers.

My OS as above being an upgrade from 7 pro to win 8 pro then downloading win 8.1 from the store in the last three months.

In the last few days I suddenly cant access my start screen/desktop after login. Even the usual custom page before the login is a generic blue background so none of my customized profiles shows its customized look.

Again, desktop/startscreen black/blank.

Able to access my files via ctrl alt del etc.

Been reading up and doing restore etc as suggested on various sites including malware scans NO JOY.I even tried to just run a repair using my win 8 pro upgrade disc but the system wont allow something like invalid media or something and I don't have media for win 8.1 pro as mentioned.

Can anyone suggest a solution please? or am I going to have to reinstall with all the internet data bundle costs included?

Visit the website of the Graphic Card manufacturer to download and install the latest Graphic Card driver to fix the issue.

Hi,

For this problem, firstly, you can try to boot into Repair Mode for test to fix this problem.

Access to the link below to learn how to boot into repair mode in Windows 8.1:

A problem seen mostly be nVidia users seems to be that the screen being viewed is the secondary of an Extended display, e.g. with the primary being either another monitor or a phantom.  Try pressing Win-P, CursorUp, Enter as if you can display and use the Project dialog to shift from Extend to Duplicate.  There should at least be a screen refresh after the Enter.

Ah.  That sounds like another problem symptom.  Users of third-party system modifications saw this recently when there was an update to some kernel modules.  So, presumably explorer.exe is not running then?  And restarting it fails?  Event Viewer could be started then and it might give you some clues.  Otherwise if you do have system modifications try uninstalling them.

 

Good luck
