I HAD PC AND THE FOLLOWING CONFIGERATION
1 WIN XO O/S
2 P3 PROCESSOR
3 64 MB RAM
4 40 GB HDD
MY PROBLEB IS INCRESING THE RAM CAPABILITIES.
64+64=128
I HAVE 64 MB RAM THERE IS ANY PROCEDURE TO ADD AGAIN 64MB RAM .How many slots do you have on you Mother Board for memory? If you have 2 and they both have a 64MB stick you may be maxed out. Depending on what your board supports you may be able to increase the size of the sticks to 128 or 256.RIGHT.    I just upgraded my DDR (RAM). I bought 2 256MB RAM cards. Upgrading is TOO EASY. Go to any computer hardware store and look for the DDR/RAM cards. Depending on how many slots you have, you can add DDR/RAM based on what you're looking for. You will need to know the computer MANUFACTURER or the motherboard manufacturer in order to get the right DDR cards. Once you buy the cards, insert them in you PC and VOILA! You have more RAM. Another thing. When you buy the cards, the instructions may tell you not to INTERMIX the card sizes (EX: (2) 256MB cards and (1) 128MB card) Disregard that. I have (2) 256MB cards and (1) 128MB card and they work fine. Hope this helps!
