I have a HP Pavilion dv7 Notebook that will not boot. It keeps stopping and going back to the begining black screen every few seconds. It quickly blinks "hit ESC key" message at the bottom. From there I have a few options where I can see system info, System Diag's, boot device options, where all tests are showing 100% ok and the there is nothing showing in the error log in this option... BIOS Setup, and system recovery. Ideas??
