Wired Keyboard 600 works util windows says it cant find the drivers  

After i turn on my computer the microsoft keybord 600 works perfectly, even show up in the mouse and keyboard center to be configured. Then after a while it stops working and windows says it cannot find a install driver for it WUT? Every time i turn on my pc, the keyboard works for a little whlie then stops again, same error.

In My device mananger the Keyboard goes from working to the code error 38 (driver still is memory), to 45 (device is not connect) to 35 (i dont quite remember about this last one).

1. I try to disable the automatic driver install,
2. Reinstalling my chip set driver,
3. Uninstall all my usb drivers.
4. Reset Bios to the factory settings,
5. Unplug from main power for a couple o minutes
6. Remove the Upper and LowerFilters from the reg

Any help is aprecieted.
