Sadly, not really. I think the key points to focus on are these:
- Photoshop tasks that historically have worked instantly now take 2-4 full minutes
- Memory usage during issue is not excessive (1.5GB out of 3GB), so memory is free / available
- CPU usage varies between 0% and 40%
- HDD activity LED is constantly lit
These are what the folks on the Microsoft forum will need to know to help potentially track down what's causing this. If you're able to reproduce it 100% of the time then that's actually good (for figuring out what's causing it anyway). A screenshot of the Task Manager when the Performance tab is selected and View -> Show Kernel Times is checked would also be good, since it gives an indication of what's taking up CPU (kernel vs. userland programs) and what your memory utilisation is (including the page file).--
