Hi,

Use this as a troubleshooter to try to determine what is causing the issue. There are many hardware, driver, and
even heat related possible causes. Also suspect antivirus and security programs even those not running or even
uninstalled without their specific removal tools as they leave remnants which can cause strange issues.

Be careful as a lot of these programs and services actually need to run and often removing a few
does little to speed the machine while making the machine less friendly to use.

To see all that is loading bootup - wait a few minutes without doing anything - then Right Click TaskBar -
Task Manager - take a look at Appplications - Processes - Services - this is a quick reference (if you have
a little box on Lower Left - Show for All Users then check that).

A quick check to see which are loading is Method 2 there - using MSCONFIG then post a list of those here.

Method 1 using Windows Defender will tell you more specific information about each program.

---------------------------------------------

This is a little more complex though you might have a few services running you can do without.

Also some programs add services which might not really need to be starting automatically.

To see these compare those in Start - type in Search box -> Services   find at top Right Click on it RUN AS ADMIN to those in the default of Vista as listed here by BlackViper. Ignore and that are on Disabled (which do not run) or Manual (which run only on demand) - for any Automatic or Automatic Delated Start you can post those in here if you need help deciding if you need to run them. A few of those could be set to Stop and
Manual so the calling program can run them as needed.

BlackViper also makes some tweaks to the default windows services however I would not do those unless you
really understand the total significance of changing a default service. So use it as a tool to compare.
