*Solution:
Press F1 to enter Setup. Check your BIOS (Basic Input/Output System) settings for anything unusual.
Press F10 to exit Setup and save any changes you made (or F9 if you want to discard any inadvertent changes).
Your PC will restart. In many cases, simply entering and exiting Setup without making any changes is enough to make this error message go away.
If the error message repeats...etc
Och
f the PC still refuses to boot past the error message, follow the PC manufacturer’s or motherboard user manual’s instructions to clear the CMOS (complementary metal-oxide semiconductor)... etc*
