That is a problem. Windows Event Viewer didn't write any event about it. I forgot about ArcGIS logs. Where are they?
My notebook is for my presentations and testing anyway (not so full of installed applications), but my home PC is another story. It is full of applications I use every day (architectural, civil and mechanical CADD, DCC applications, GIS applications and tools, web servers and web design tools ...). Reformatting and getting into current state would probably take me 10 days
