You need to reset the BIOS to system defaults as it appears to be corrupted.
You can either remove the motherboard battery for a few minutes or check with the pc manual for the jumper settings.There will be a jumper near to the battery that will reset the BIOS back to factory defaults.
You could try opting for load system defaults,but if the CMOS has become corrupt it might not solve the problem.Clearing with the jumper or removing the battery will reload the CMOS completely from the BIOS ROM on the motherboard.
The appearance of the motherboard name is just a setting in the boot sequence for the BIOS...something like "display logo".If set to yes you will see that instead of the memory check etc. you are used to seeing on boot up.
