I have some issue which I cannot even guess where to begin with solution. In one personal computer I have an application from which I don´t have the installation media. The previous owner lost it.
My motherboard (LGA775 sock) failed and I had to replace the motherboard and the CPU. I created an image of the original hard-drive and cloned it to a new drive (SATA to SATA). This is perfectly working now. I installed the new hardware drivers and the service packs (SP2 and SP3).
This was necessary because the new hardware components was not all recognized by the OS with SP1. (this was the original installation status)
Right now the application which I noted at the beginning is working too. It starts up and it also works.
The problem is that in some point the application hangs and cannot be killed even by task manager.
Thanks for all suggestions.
