I have an HP Pavilion desktop computer that's going to hit its 6th birthday in a few months, and it's gotten much slower in its old age. It never was a powerful computer, but my needs aren't extravagant, and it's served me fairly well. I use it mostly for web browsing, video streaming, iTunes, and as of recently, a bit of audio recording and editing using Audacity. Every once in a while, I go through my startup processes and clear out some unnecessary ones. The extent of the purposeful multitasking that I do is running iTunes while I'm browsing the web (and that slows my computer down considerably), and that's about it. The hard disk light on the front panel of the tower is usually flashing very quickly or just remains steadily lit. I don't have all of my exact computer specs on hand at the moment, but I don't have an SSD, I have 4 GB of DDR3 RAM, and I have an AMD processor.
Last fall, my power supply blew out, so I replaced it and when I opened the tower, I saw that there are no additional slots to expand memory, but would simply replacing the existing RAM help with the speed issues? Thanks in advance!
