Problems handling Excel files

New Contributor

Since yesterday I have problems opening and handling ALL my existing Excel files.
Especially the files with included graphics.
This has also impact on Windows Explorer.


When clicking on a file, the message that Excel is loading appears: First 0 %, then 100 %.
Sometimes it stays like that.
Sometimes it opens after a very long time.

Then I see the data, but a gray square on the place of the graph.
After another long time, the graph is visible, and I can add a line.
But it takes minutes to add data, between each cell.
The message at the top days: Excel is not reacting.


If I abort the opening by closing the Excel window, Windows Explorer blocks also.
Then I have tot restart Explorer via the task manager.

However, I can not give it a try to reopen the same Excel file, because it will only open on read-only, giving the impression that my previous try is still active.

I am using Windows 10 with Microsoft Office 365.

I already did, without result:
- A repair of the full Office 365 suite.
- A full Virus scan, including my Malaware tools.
- A cleanup with CCleaner.

I have send one of the files to a friend and he has no problems opening it. So the problem is not in the file but in the system.

There are no problems with other Office applications.


Any idea?

This problem can be closed.

Because no solutions are received, I solved the problem by buying a new PC.
