Laptop running ridiculously slow..

Hi, first-time poster here so hope you can help me.
My laptop is running really slow, particularly on the web, even though I have 2mb broadband. Most applications I try to open take up to 2 minutes to open and the mouse pointer appears to freeze. Not just the mouse but the laptop and any application running can freeze but when you move the mouse pointer it starts up again from where it left off. I.e it's like a pause button. This is the same whether or not I use the internal mouse or an external one.
I've ran loads of antivirus and spyware including:-
Lavasoft Adaware, Spyware Blaster, RegistryFix, PCBugDoctor, Avast Antivirus, Xoftspy, CC Cleaner, Spybot and AOLs own virus scan. I've also ran TrendMicro and Panda Software on-line virus scans. Only the odd small thing showed up which I've removed/fixed.
I guess I may have too many processes running but don't know which ones I don't need or how to turn them off so they only run when needed.
I've downloaded AIDA32 as recommended on this site but don't know what information to post. This is the system info for my pc

This is only a suggestion, as the moderators don't like users telling others to post in other sections of the forum, but since you've done all that you mentioned, with no improvement, it could be in your best interest to visit the Spyware Specific forum, read and follow all the sticky notes at the top and see if this helps!

 

Process Explorer will tell you how many processes are running, and what they are.
