Computer Startup Slow?

What we usually do in this case is "msconfig" and disable all my "startup" programs that I dont need and maybe even some services that are not "Microsoft".

Try that then reboot and add the programs 1 by 1 rebooting after each to find the culprit program/service.

In case you dont know how to "msconfig" all you do is:
1) click start
2) click run
3)type " msconfig " without the quotes
4)uncheck unwanted programs/services from the "startup and services" tab.

Another option would be to open task manager, click on Processes, and sort it by Memory (descending).

That may also tell you which program is taking up the memory.
