Checksum error Hi, Im Oliver, my computer give messege like this BIOS ROM CHECKSUM ERROR, what can i do? please help me>>

Hi Oliver, the most common error related to the message,
(Bios Rom Checksum Error). Someone has left a floppy disk in the floppy drive. Once the floppy disk has been removed press the reset button on the PC, your windows will start normally. Next place to look is in your bios.
Open your manual to page 27.
Enter your bios & go to the title Advanced BIOS Features. Check First, Second & Third boot devices they should be as follows. Floppy disk drive, CD-ROM drive & primary hard disk drive. If both of the above are ok than try clearing the cmos/bios by resetting the cmos jumper (JP1) location on page 5. Descriptions of page five on page 6. CMOS settings on page 9.
When your system restarts re-enter your cmos & reset up your bios settings. Lastly if none of the above has fixed the error message, than remove the cmos battery & check its voltage. It should maintain 3volts. If yours' is lower than 3volts replace the cmos battery. There is one other possible fix. It’s an option not given lightly. Flashing a cmos/bios is not recommended unless all other options have failed.
