Question : PC failing to start

For the last few weeks my PC is failing in its start uo procedures. It seems no great problem as I select F1 and the start uo continues.
I wondered if anyone can identify what may be wrong and what I can do to rectify the problem.
Many thanks

Answer : PC failing to start

Try to load the default settings from BIOS Setup. by selecting load degault and reboot again and see if the error still persists. If the problem does not show then test again by shudown the server and again turn it back on and see the error again appears or not.

If the error appears then,  the CMOS battery needs to be replaced.
