Non responsive Omen X 17 after attempting overclocking with Command Center

[austmills]

hello all, not experienced in overclocking. I thought I would try the “intelligent” mode in Omen Command Center. It attempted to overclock numerous times, hanging at 40% complete, rebooting many many time. I assumed this was part of the process. Eventually made it to 80% then the same cycle. Finally it made it to 80% and stayed more stable working its way up to (I think) 100%. Some screens flashed really quickly and it rebooted. Now I cannot get anything to happen on reboot in terms of the built-in display or an external display. I am trying to enter bios or get any reaction at all and I get nothing. Any suggestions out there? 
Edit: I should clarify that I hear fans running (low) and the keyboard and case lights but that is all.

With HP tech's help, pulled the battery, power drained, back up and running. Thought it was a long shot but it worked.
