just make sure you get rid of all old files and compressed stuff hun.If it aint that its gonna be your pc's memory.Its just not able to cope with the speed in which you want it to work....like do you click the links once and as it loas re-click it to speed it up??? becaue if you do this the pc has a spaz attack and freezes up and show a white blaank page.
Also be sure to d/l any windows updates and try run a virus scan to be sure you got no bugs.
Hoep this helps if it dont holla at me when im on msn hun.
edit: i just noticed from the picture you seem to have an awful lot of stuff running for a dial speed connection.If you can help it turn of any background programs that are running that you dont need to fee up memory usuage.
hold down ctrl+alt+delte.....this will show you 'windows task manager' screen. Just have a look at what programs are using the most memory and see if you need them on or not.A high usuage is anything above 10,000k just so you know what is considered high usuage.
NOTE: dont stop anything unless u are 100@ u know what it is....you cud even right click the icons in the bottom right of your screen (next to the time) to stop any usless programs running.
