yea, it's me again. brief info... right now, I have 512 mb of ram. I want to upgrade to at least a gigs worth. so my dilemma is, everything about my desktop is sort of out dated (dell pc...celeron processor, everything is integrated (from video card to sound card...basic pci slots, no express). my question is, can I still upgrade my ram (512mb dual channel DDR SDRAM at 400MHz), with this POS comp, or do I have to save up and invest on a new "updated" comp?? (which I am not looking forward to do anytime soon...low funds) Dimension 3000 - Celeron Intel® Celeron® D Processor 330 (2.66GHz, 533 FSB), Microsoft® Windows® XP Home Edition if the answer is yes, (as in I could still upgrade my ram on this shitty comp), any recommendations on what specific ram I need or should get or what sites I should go to for the good deals?? I heard I need to match ram in order for it to work correctly...don't have a clue on what ram I should be looking for. all I know is that I want at least a GB worth of ram. I am noob, PLEASE HELP!!!
