Hi there, small question!
What is your page file sitting at right now?
You can turn this setting on and off by right-clicking the Computer icon, clicking the Advanced System Settings link, then clicking the Settings button under Performance, then the advanced tab.
My CPU is at 0% during idle, and page file is 4934MB
Please note, I have 4 gigs of RAM so my paging file is larger then someone with less RAM (yes these numbers are seperate), also, please let us know your hard drive size, so we can determine if you are able to have the required space for the paging file.
Finally, I would suggest this:
Disable the .XML file extension from being indexed in the Indexing Options control panel.
Good luck guys.
