Welcome to the forums, Rasputin

If it used to be fast, my first thought would be to check what you have loading at startup. For example, do you have lots of things loading when you first turn your system on, sitting in the system tray. To check, right click the taskbar (the black bat at the bottom) or start button, and click "
task manager". Now, view the "
startup" tab and see which applications have a "high" or "medium" startup impact.
You can post a screenshot here if you'd like and we can give advice on which things you may be able to disable.
Do you have an SSD in your laptop? That's a sure fire way to speed things up for around $90/£80 - but it would involve making hardware changes.
