I understand that windows only utilises 3-3.5GB RAM, correct?
I also understand that sometimes graphics cards will take some of the RAM, 512mb for example, correct?
However before I upgraded my graphics card, my system showed 3GB of RAM. I then added the new card hence it went down to 2.5GB - thats fine with me.
I then used all the 4 allotted RAM slots (1GB in each, total of 4GB)
My computer now still just shows that I have 2.5GB, am I wrong in expecting this to be boosted back upto 3GB of RAM as I have put in more physical RAM? (4GB)
I am assuming that as XP will only utilise in my case 3GB of RAM, it makes no difference how much RAM I put in the graphics card will still take a certain amount and as it falls within XP's limits I won't notice anything differnt unless i use a different card?
THIS MAY THROW A SPANNER IN THE WORKS HOWEVER:
I have tried putting a simple 2.5GB in my system and with the same card my system shows all the 2.5GB. This would indicate to me that the card was not using sytem meory - it is if something may have broken down at some point as it did once show the full 3GB I initially had.
Sorry a bit long winded but I was hoping someone out there may have some ideas on how to show at least the 3GB again.

You didn't tell more details about your problem with your graphics card so I can troubleshoot what will be the problem with it. Before I solve it, lemme ask you a few question:
Since your OS is Win XP, is it 32bit or 64bit? What is your CPU frequency clock speed? What application does your graphics has a problem? And also, what is your monitor's maximum resolution? And what is your mobo (sometimes this has some source of issues).
I'll wait for your response to this. Thank you.
Update the graphics driver for this computer, another reason for this is a low grade graphics card, or low ram which does not have enough grunt to run in full screen, download VLC media player and try that as it uses far less ram that windows media player. cheers
Make sure that when you populate the memory slots that you are using like memory cards per memory bank set. Example: A1 and A2 consist of one blue and one beige slot. Use a 2GB card in one and a 2GB card in the next one. Starting with A1, use your 2GB memory cards first and then the 1GB cards. Once complete, reboot your system and enter into the BIOS to verify the total 12GB are being "seen" by the system.
Also, consider your os. If you are running Windows Vista 64 bit, Windows 7... they will only see 8GB max. OS like Windows server xxxx will be able to see all memory avaliable to the unit.
Depends on what kind of hardware you have
2 gb ram is "ok" if you use windows XP but if you have Vista or Windows 7 you should have a minimum of 4gb ram.
if you have a Dual core processor you are ok, if you have a p4 or p3 you dont want to waste money on a new graphics card because it will not help you get better games, your processor and memory will slow you down instead.
So my advice is, if you have a OK computer, go ahead with buying a new graphics card
if you computer is old and slow, DONT buy a new card! put your money on +2gb ram instead (cheap,and gives you more benefits) or maybe buy an "upgrade package" with new motherboard-memory-processor.
From your explanation i understand that you have to restart the PC if you try to run a game or some time while browsing on internet because it goes blank randomly.
Well while looking at the symptoms it make pretty sure that this might not be the issue of heat as you said but this might be because of the RAM or Graphic Card and why that would be the reason is like only while you try to run a game or while watching a movie clip, graphics the RAM or Graphic Card is extensively used for the video performance and system file execution(for gaming), so at this point of operation if there is some conflicting software or if the RAM or Graphic Card fails to cope-up with the CPU speed will lead to system crash or screen goes blank and must restart the PC.
so in order to fix this problem you have to carefully check the RAM and Graphic Card for any circuit burns, loose connections, and you can check if you RAM is OK by using the memory diagnosis method used by LINUX OS.
if you have onboard graphics card that shares the ram memory with your graphics card then the configuration in the bios will determine how much memory is shared with your graphics card so you will lose memory there. Also windows xp does not always report the correct amount of memory so check with cpu z or wcpuid or another utility to check.
Also when you restart your computer when it detects the memory how much does it show that is installed there or if you go into the bios does it show the correct amount.
If it does not then it is not compatable and I would suggest going to www.crucial.com and selecting / getting the correct memory by selecting the correct computer / motherboard that you have.
