Assuming you are NOT using the onboard video (meaning you actually have a physical video card and not just the video from your motherboard) Assuming you are using the only USB for your mouse and keyboard and NOT Ps/2 port mouse and keyboards Assuming you are NOT using an old printer which uses a parallel port If all above is true, continue... If not all true, please stop now. Log into your BIOS or UEFI Disable the assigning of parallel port addresses. Which seems to be found on even motherboards which have no parallel port -- On some motherboard's it will simply be labled as the automatic assignment of IRQ addresses via the CMOS (Disable the whole thing if you can). Reboot Speed. Nothing but pure speed. Bonus: Disable ps/2 port for older mouse and keyboard (assuming you are using USB) Disable onboard video (assuming you're not using it and actually do have a video card installed) The 1st two I've always done. It is only recently that I've learned just how much disabling the parallel port has its advantages. For years, I've always left that alone and wow, was I surprised to discover just how smooth it all works without it. It suddenly feels as though I have all new computers.
