Thanks for all the help.
Im at work so i will try all your ideas when i get home tonight. In the meantime just keep them coming
To answer the questions i can from work.
-Ive tried all the usb ports, works fine at first then mouse light never turns on after 34 min. mark
-i dont get any error messages
-the mouse and keyboard (numlock) light go out at the 34 min, mark, and the mouse pointer disapears from the screen, if i switch usb port i still get no power
-they stop working just before the installations first setup window appears asking for name and organisation (that window appears when the timer shows 33 min. left)
- i deleted all partitions before starting, formated ntfs.
-After the usb stop working i tried again, deleted all partitions formated again. same problem
