I have a Compaq Presario V5000 laptop that has a Sempron 3300+. It had 512 Mg of Ram less the ram stolen by the video. I took out one stick of 256 Mg Ram and put in a stick of 1Gb which gave it 1.25 Gb of ram less the ram stolen for the video. It still runs about the same speed, when I play music and then try to open a file it breaks the music up so that you can barely undestand what is playing. I have run it through two different anti-viruses, and anti-spywares. I have made sure that the defrag is done. What can I do? Is there something wrong with the new RAM? It shows up OK as 1024 Mg? It just doesn;t seem to have been speeded up? Any ideas?
