BIOS Reset Help

I have changed the DIMM's in a computer in order
to upgrade. Since then, all I get when powering
up, is one long beep followed by two short beeps.
I understand this is a memory error. I have re-
installed the original DIMM's but the error persists.
I have removed the BIOS battery and re-installed,
no good. I tried shorting two points close to
the battery in order to "clear CMOS" also without
success. Is there another reset procedure?

Look closely at the DIMM sockets to see if while installing the memory
you bent some of the pins.

What motherboard is this ?

Your symptoms so far, suggest the new DIMM has
damaged the motherboard.

Is this DIMM from Ebay, or did you buy it locally
from a computer store ?

A few more details about the parts being used,
would help.

Yikes! what are your folks doing with your ram modules lately?
When you say 'no good' are you refering to the fact that it did not solve the problem or
you did not accomplish the 'clearing'?
Usually if the cmos gets cleared you get 'Checksum error, F1 to enter setup' or something
similar during post.
Were you able to lock down the modules with the clips provided?
You are aware that the modules have grooves the the sockets have an opposing extrusion to
fit the module?

I thought that one was video problem. Make sure you didn't bump the
vid card when you were in there.

Its certainly possible to physically damage a motherboard
when replacing dimms when the board isnt adequately
supported in the dimm socket area and one of the dimms
is a very tight fit. The motherboard can be flexed enough
to damage it if you dont support it when inserting the dimm.

Did you get an error message on power up about a cmos checksum error ?
You should get that if you have reset the cmos properly.

You need to unplug the mains from the system
to reset the cmos properly with some systems.

So true! It is frightening how the motherboard
flexes when inserting DIMM's. I put a rubber pad
underneath.

The computer is basically dead after the three
beeps :-(
