It has been pretty quick all the time, but in recent weeks it's running like molasses, and I have no idea why. The hard drive is only half full, recently defragmented, I checked for viruses and there are none. I've tried spybot to get rid of spyware but every time I start the scan the program just closes itself. Some stuff is really quick, but other things just take ridiculously long, and sometimes just freeze up. Like right-clicking on icons, sometimes the properties menu takes 30 seconds to come up. Some webpages just won't load while others are fine. It's getting really annoying, because I have to do school work on this, and I can't be losing my files or not being able to open them.
