My girlfriend had a 3 year old hp that has become horribly slow recently. It is running windows 7 and had only 512 mb of ram. Upgrading ram is not an option due to cost. Would win ready boost help? So far I have tried running eusing registry cleaner, ccleaner, and avg to check for viruses. ETA: it has also had regular disk defrags The startup time and shutdown time are horrible, and something I can't figure out is whenever I run ccleaner, even after only 40 mins of light use, it finds 200-300 mb of stuff to delete. What could be building up that quickly? On my brand new laptop it never removes close to those numbers after a week of use, and my new laptop has 4gb of ddr3 ram and an i7 processor. Any help would be greatly appreciated. Thanks, Nathan Wanna kill these ads? We can help!
