I just did the same this past weekend (replacing a faulty hard-disk) reloading Windows XP SP2, updating all drivers, etc., and TradeStation 8.1 Build 3159 works fine. I applied some indicators to a 100 tick chart of @ES to test it just now and see CPU usage well under 5% in the Task Manager.
Ideas: Did you flash the bios with the latest version? Some new driver versions might need that.
The support guy at Dell said to load the drivers in a particular order and reboot after loading each one. Here is the order he gave me:
System: Dell Notebook System Software Driver
Chipset: Intel Mobile Chipset Driver
Video: Video Drivers
Audio: Audio Driver
Network: Internet Controller Drivers
Comms: Modem Drivers
Network: WiFi Drivers
Input: Touch pad Drivers
BIOS: Flash BIOS
Other: Applications then Patches to Applications
I have not yet tweeked XP for performance. This was the default installation.
Hope this helps.
