I have done a HP System Board check with the following failure:
Test result failed failure id PGBX90-000000-WPTX01-A0WE03
Driver CQCPU.SYS may not be present or be present in its proper location........... Any clues to what they are talking about I called tech support and they said they would be glad to help me for a nominal fee I'm broke spent all my cash trying to fix Best Buys negligence :-(
