Wow, that's alot of startup programs. That must be the problem.
Look at the startup item name and anything that's not required or irrelevant, disable it. (Usually most of them are except for essential system programs like audio and video)
If you're unsure what it is, you can always google it and see if you need it. Since your PC is customed to you
I'm sorry that I can't help you here. Let me know if you have any questions.
