Hi, my computer has been running really slow lately and when I run alot of programs simultaneously, everything on my computer seems to be lagging and I have to take my hands off the computer for a minuto to let everyhing get back in palce then I continue. I am 99.99% it is not a virus or malware thing but instead a lack of memory or resources. I have gotten a low memory message a few times. I think I need to upgrade my memory, but I do not know anythint past that. What type of RAM should I get and what gives you the most bang for your buck. I am running windows XP and here is a picture of my specs if that helps you determine anything.
