You probably need to clean or replace the screen inside your brew unit. I recently just cleaned mine due to the same issue with some steel wool.

If any new programs were installed that could be the issue. If you are using apple iphone products then stop the applemobilephotohelper service. This really slows down startup and also slows computer.

There is no governor. Some machines have a slide speed adjust control on the front of the machine. But there is a chance that your machine is just slow. Look up the stats on it. For home machines 1100 stitches per minute is really fast.

Try the process of elimination. Take out the needle, take off the needle plate, take out the bobbin case. Run the machine. Does if run full speed? You might have to let the machine run for about 5 minutes. If it runs slow or you hear it slow down, you might have a bad connecting link between the needle bar and the main shaft counter weight. They seize up sometimes. (Shop Repair).

First thing I would do is take the desktop outside and clean it out with two cans of compressed air.

HEAT can really slow a machine down. Let me know if that makes a difference (good to do either way) and we'll go from there.

wipe the hard drive and stop using it for porn

Check for possibly fuel line leaks

Try plugs and wires as well

Try running Spybot (http://www.spybot.de) and avg on it. run Spybot several times (rebooting after every attempt) untill it finds nothing. If you built the machine are you sure that the processor heat sink is correctly installed and not over heating? What is the speed of the drive?

Beatriceccc: This can frequently happen when Vista runs on a computer that's hardware just can't keep up with it. I'd like to have you try this for me. Click on your start menu, then "Right click" on "computer" in the left column.This will take you to a page, that will give you something called the Microsoft Rating. If you can comment back to this post with the details of the overall rating, as well as the specific categories, we'll be able to provide better assistance.
Was this computer pre-installed with vista? or did you upgrade from XP? What is the model number of your machine? All of this will help us to help you.
