The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

BIOS ROM Checksum error

Asked by Pyrotekniks in Miscellaneous Hardware, Hardware Components

Tags: checksum, rom, bios, error

OK, you fix PC's on a daily basis and usually go through three a day, but when you get stuck on the same one for three days straight and the vein in your head starts throbbing you have to turn elsewhere.

To begin with the PC would not display anything, and after checking VGA cards and slots, I swapped the Motherboard for a brand new one.

Now, on boot up the PC will get as far as saying:

BIOS ROM Checksum error
Detecting floppy drive A media...
INSERT SYSTEM DISK AND PRESS ENTER

I have no way of entering the BIOS to change settings and the HDD and floppy drive activity lights are constantly lit.
I have read a solution here explaining that it could be a virus that is messing up the BIOS and have read that the only two things that could be at fault are the Motherboard or the BIOS chip.

So, being in a workshop I swapped the motherboard for a new one complete with new CMOS battery and new BIOS chip, I still have the same error. Have tried the jumper settings that resets the CMOS.

If there is a virus, i'm wondering whether it originates from somewhere other than the Motherboard and I have just wrecked another one.

Please stop my head from hurting
Thanks
