Hello everyone, Plz help me. I have 128 MB SDRAM on my HCL PC, I bought 2 1/2 years ago. Now, I think using WIN XP SP2 with lots of programs makes the system very slow. So, I am thinking of buying additional RAM. Now, I wish 2 buy about 128 MB DDR-RAM. Will it run together with SDRAM without any conflicts?? Secondly, how much will it cost for 128 MB DDR-RAM?? ------------- Secondly, I have NVIDIA RIVA TNT2 Model 64/ 64 Pro as my graphics card. So, I can't play games like NFS: Underground 2, FIFA 2005, Prince of Persia: WW, etc. and also not run programs like NASA World Wind, etc. I wish 2 buy a new graphics card. It should not be much heavy on my pocket but as a home user, I don't need a very very very good card. A card which can mostly run all things upto date is preferred. Also, if possible mention the cost.
