I dont know if this matters or not but we had a computer running vista with a better video card then mine and it ran like crap. We removed the "search" that always indexes the computer and its like a new computer. everything is blazing fast. Thing is, if anyone that has xp pro / vista and they just hit "update" in windows update, it will dl it and run it without telling you. I think the windows task manager shows it as searchindexer or indexer. Here is some info on it.

I will tell you NOT to DO ANYTHING that you dont know how to do. If you bork your computer then its YOUR fault!

"To achieve the fast searching speed, indexing service plays a pivotal role. Windows Vista starts to crawl and index files on hard disks right after installed with a low priority background process. If you notice that your hard drive activity LED light is constantly flashing even if is idle, this is probably due to indexer at work."

" Disable Windows Search Service
This method effectively stop and disable all search indexing processes, and is the recommended way.

1. Click on Start button, then select Control Panel -> System and Maintenance -> Administrative Tools, and double click on Services applet. Alternatively, simply type “Services” (without quotes) in Start Search box.
2. If User Account Control asks for permission, click Continue.
3. Locate an service named Windows Search. Right click on Windows Search, and then select Properties on contextual menu.
4. Click on Stop button to stop the indexing service immediately.
5. On the Startup Type dropdown box, select Disabled.
6. Click on OK button. "
