Hi, I recently got a windows 7 ultimate sp1. As soon as I enable hyper threading in the bios, I get stuck on the starting windows screen. My CPU usage is above normal (15% instead of 2%). I have an Intel Xeon L5640 @2.27 on an HP z400 with 3tb of storage and 16 gig's of ddr3 ram @1366mhz. The GPU is a gtx 950 xtreme oc edition. Please help, I'm very stressed about all of this.

YOu have what processor? I can't find an i5-640 anywhere....; do you mean 650?

YOu might need a repair install, and, it can't hurt to reinstall MB chipset drivers.....
