Please see below.
Go and everyone else who has contributed - many thanks for your advice.
I am not too good with computers but just know the basics. I think that you
are correct and I've become horribly confused. I was looking at the first
screen (which you say is the DOS screen) and didn't know that 128MB of RAM
was the maximum that can load. Right clicking 'My Computer' does show 512MB
of RAM.
I had a problem some months ago when video games and sometimes other
applications locked up totally and I had to restart. I was advised on another
forum (or possibly this one) to alter the BIOS setting 'DRAM Timing Settings'
to an 'AGP Aperture Size' of 256MB i.e half my total RAM. Does this mean
thereforethat I have lost 256MB of my RAM before I even start computing?
I will ask my original question again and hope that someone can answer it.
If I buy another 512MB stick of RAM will I see a big difference in
performance or hardly any? If I did buy the stick and installed it should I
up the 'DRAM Timing Settings' to an 'AGP Aperture Size' of 512MB or leave it
at 256MB.
Many thanks again

Does this tell you anything and if so is it incorrect and how do I remedy
the situation? As I said earlier I was going to buy a similar 512MB and put
this in - would this help?
Thanks
Could you tell us the make and model number of the motherboard ?
Or, if you bought the computer from Dell or HP, what the make and
model number of the computer is ? (Because we may be able to figure
out the motherboard and chipset from that info.)
Some chipsets have limits to the range of addresses they can generate
for row and column address. If you plug a 512MB DIMM into a chipset
which supports 256MB sized sticks max, sometimes that will register
as a 128MB stick. The reduction in capacity is due to the limitations
of addressing in the hardware.
Usually, you'll get some warning of this, if you visit Crucial.com
or Kingston.com and use their search engine for memory upgrades.
Based on seeing the limits of the size of memory they are selling,
that will give you a hint as to what DIMMs might be too big for
the computer.
