New laptop can be slow and freezes.

[Volcanic Murk]

My (relatively) new laptop that I had for a month can be slow and freezes. It used to be fast, but it suddenly started to suck. Every window that's up freezes and says it's Not Responding. When I click the window, it turns transparent white or gray. After a few minutes, and sometimes seconds, it returns to normal. I get frustrated sometimes and close it so it can sleep and work again when I open it, but it takes a long time to sleep. And sometimes it can be painfully slow, especially when staring up. I still have a lot of memory and data left on my computer and I did not download any harmful software. Why does this happen and how can I fix it? My laptop runs on Windows Vista and I'm upgrading to Windows 7 soon.

Do we get any info on what kind of laptop it is? A manufacturer? A model number? Or at leased some specs?

Sorry, forget to add that. My laptop is a Toshiba Satellite.

While I don't know a large amount about computers, I'll try and help.

When was the last time you cleaned out your cookies or defraged your hard drive?

Go into the task manager and see if any processes are eating up a lot of your RAM/CPU.

I clean out cookies regularly, so I don't think that's a problem. What does defragmenting do and does it delete any files or change them?

Edit : The error is called AppHang B1. What is this and how can I fix it?
