There are several error messages of BIOS like CMOS CHECKSUM FAILURE, Wrong Memory Size, CMOS BATTERY FAILED, etc. If your computer has one of these messages, simply start your PC normally with the parameters default BIOS. To do this, enter the BIOS by pressing the desired key. It depends on the BIOS and is usually indicated on the screen. If this is not enough, you can try to reset the BIOS as described above. If the problem persists, change the CMOS battery.

A beep during the boot sequence indicates a hardware problem before launching the graphical display, these beeps can have various meanings. A message in this sequence indicates either a configuration problem or a hardware problem. In general, an error message is often the resolution by changing the BIOS setup. The beep usually refers to a RAM issue.

KB / INTERFACE ERROR, this error message error indicates a bad connection at the keyboard or a malfunction of the any hardware. Check it is plugged in correctly and if the problem persists, try another keyboard. It is also possible that this problem is the result of a bad BIOS setup. For example, if a USB keyboard whose use must be specified in the BIOS.
