Computer not recognising my shiny new RAM.
Jelenedra:
That could be it. When I upgraded to 2 gigs, my shiney new Kingston hated my PNY. So, I went and got two kingston.
The way to check for this though, would be to remove all the sticks but the new one. If your PC can read the new one, that means that it is a compatability issue with the other RAM. If it can't... you got a busted stick. Return it.

Thanks. I'll give that a shot when I get home.

Until today I had 3GB (three 1GB sticks) of RAM in my computer. I wanted to buy some more (since I upgraded to Vista) so I picked up a 2GB stick to fill my remaining slot.
I'm assuming you installed the 64-bit version of Windows Vista yes? If you're still using a 32-bit OS (like Windows XP or anything below Vista Ultimate unless you request the 64-bit disc from Microsoft) the higher memory simply cannot be addressed (each section in memory needs an address, for example 0x00A64CFF - made it up just for illustration; once you run out of spaces ie. 0xFFFFFFFF the pc can't see anything past that.)

@Argon, I'm running the 32-bit version. 64-bit doesn't support sli apparently and I have dual video cards.
After doing some more research I found a few possible ways to work around my problem.
I enabled PAE, following the intructions here: http://vistarewired.com/2007/03/29/how-to-enable-more-than-35-gb-of-memory-in-32-bit-windows-vista/. It didn't change anything.
I downloaded Vista service pack 1 and installed it. This did actually make a difference. My system menu now says that I have 5GB installed. However, dxdiag still says that I only have 2GB installed.
I'm not really sure how trustworthy dxdiag is since it displays the incorrect amount of memory for my dual video cards aswell.
My system is certainly running faster; but as to whether that's from the newly recognised RAM or the service pack I don't know.

Huh? I'm running Windows XP and 4 gigs RAM. It definitely recognizes it and, since I upgraded from 2 gigs to 4, things like flipping between programs like Photoshop and SimCity4 and Sims2 are almost instantaneous. It's a definite improvement. I see the correct amount of RAM listed in dxdiag and under Help and Support Center...Computer Information:
Processor Intel(R) Pentium(R) D CPU 3.00GHz
Processor Speed 2.92 GHz
Memory (RAM) 4096 MB
Operating System Microsoft Windows XP Home Edition
Operating System Version 5.1.2600
