removing a bad dimm

I've got a PC with 4 memory slots. 2 256MB DIMMs are in slots 1 and 2.
2 512MB DIMMs are in slots 3 and 4.

About 75% of the time when powering on the computer, I hear three
system beeps and the machine completely halts.

I was wondering if, once I've indentified the bad DIMM, if I could just
remove the bad DIMM and use the PC without it? I've tried removing the
2 512MB DIMMs and booting without them, but when the machine powers up,
it just halts right away (no beeps or anything).

Does anyone know how to do this?

Thanks,
Jacob

i have an older system, one of my spares, that requires 1, 2, or 4 sticks,
3 will make it fart, regardless of matching sizes, maybe that is whats
wrong with yours. soimetimes also you need to make sure the sticks are in
the lower numbered ram slots.

I would start by clearing the CMOS first before installing the ram in
a different configuration.
You have not posted the model of your board or the ram?
Some motherboards make you wonder why they have 4 DIMM slots with the
anomolies they cause when you use all of them. At the same time I
would have a look and see if there is a BIOS update for your
motherboard

There is no harm installing each stick of ram in the system on it’s
own to help figure out which one is the problem.( Don’t forget your
BIOS configuration for enabling and disabling dual channel mode)

If one of the 256Mb sticks is faulty then it’s not too shoddy to have
the two 512Mb in dual channel mode and a spare 256Mb stick in the
drawer.
I don’t know how much benefit more than a 1G of ram really is anyway.
Then again I don’t know the specs of your computer.
