Excel 365 High CPu usage

Guys. Another issue not VBA-specific but it's important. I have an excel file and it's worked just fine. Without any huge changes, currently if I do something i.e change a sheet , jst try copy a cell my application is just freeze and in task manager the CPU show me a high % of usage. GPU-0 3 D- just will be visible and the power usage change from low to very high. I run the file without releasing VBA, but the result is the same. What it is? Excel 365. (Yesterday i did a reinstalling process.) You can see a short movie with explanation related to this issue. Attached to this message.

 

Thanks your answers.

    Hi there. Honestly no. I stopped my project, started 5 years later a new, and the problem solved, there was no CPU and GPU peaks. I think it was an external hacking attack.

    ZsoltF418 I'm getting exactly the same in Excel 2013. I notice it's using the GPU. I wondered if there was a display driver issue? Did you ever get anywhere with solving it?
