Okay, so I don't have a macbook but this is the main forum where I know I can trust people. Hope this is the right place to post. I have an HP dv2910us that I bought 2 years ago. I haven't had too many problems with it so far. When I turned it on today, it was really, really slow. I noticed that the RAM usage is around 85% now when it used to be around 35%-40%. Is there anything I can do besides installing new RAM? I uninstalled a few programs but I don't think that did anything. I'm just wondering why it suddenly doubled recently. When I opened it up today, the screen was blank but the computer was on so I did a hard shutdown. When I started it back up, it was super slow. Any suggestions? Thanks in advance.
