Overheat? to spontaneous shutdown 1-2 min reboot, after reboot displays black screen with text CMOS

HP Recommended
hp 15-cc060wm
Microsoft Windows 10 (64-bit)

system acts like it overheats and then spontaneously reboots with text on black screen saying CMOS Checksum invalid Cmos reset 502 (i have however replaced the Thermal paste with a better application and have seen some better performance)

 

What do i do to remedy the situation, Ive looked all over the Motherboard and there is no where it has a place for a CMOS so why am i getting a CMOS error Possible Bios error?

@Crum106

Thank you for posting on HP Support Community.

 

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

To resolve the CMOS Reset Error (502), restore the BIOS.

  1. Press Enter to restart the PC.

  2. If the error displays after restarting, try to restore the BIOS using a USB drive. For more information, see the "Recover the BIOS using a USB recovery drive" section of the following:
  3. If restoring the BIOS fails, contact HP.

Hope this helps! Keep me posted for further assistance.
