Hi!

If the caps lock is blinking twice it mean the bios is corrupted

You can try to rollback the bios, press and hold the windows key then press hold tas well the letter B, while holding those keys power up the pc

If nothing happens, try to power on again but immidiately tap ESC repeatedly , startup menu will appear on the screen.

If you dont have the start up menu, try to power on again then immidiately tap F2 or F10

In F2 there's an option BIOS management,  choose the option ROLLBACK

IN F10,  set the bios into defaults by pressing f9 , then f10 again to save the changes and reboot the system.

Thanks!

Thank you for the response. I still get only the blinking cap and num light. All other lights stay on. Nothing on the screen or an external monitor.

Thank you all for your responce.  I resolved the issue be taking the battery out for a month and letting it sit.
