Motherboard damaged after CMOS change

[SambhajiDhapte]

Hello,

I own a 2.5 Ghz core to duo machine with Intel motherboard (Not able to find the number on the board). I removed the CMOS battery and replaced it after 24 hours.

Now my machine won' t boot as it used to. Now I have to remove the battery for say 10 min and then insert it to start the machine. Then it says 'CMOS checksum error'. After this the machine works fine. Then if the machine is shutdown I have to following the entire procedure again.

I have tried resetting BIOS, cleaning RAM, Replacing Cmos battery, Disconnecting all power cables and reconnecting.

The mechanic told me that the motherboard is damaged and cannot be repaired. Need to replace it.

Could you please suggest whether I should go ahead and replace the motherboard or go for second opinion?

1| When dealing with troublehsooting threads it's always a good idea to pass on your full system's specs. If you're having trouble verifying the parts, it's always a good idea to pass on pictures.
2| Have you tried using a fresh CMOS battery? Often times batteries will loose charge in spite of being intact so perhaps buy a fresh cell and try it out again.
3| Your PSU may also be the culprit but until the specs come around, we're left guessing who the culprit is.
