Blogger: I can't say without looking, there's a number of factors that can be causing the slow boot times. If it has changed since the Geek Squad had their hands on it, then they can fix it. They probably changed some things, or didn't reset or tweak some things, BIOS settings, drivers et al, for a new motherboard. There can also be starup programs that were not there before, can't say. It's never easy to diagnose 'puter problems in these forums. If you have a geek squad type friend perhaps he can come over and correct it for you. If not, you might have to take a trip. Another option down the road would be learning more about your system, because, despite the best efforts of M$, Dell, HP and others; it's not an appliance, and they're all different. It is an intricate, complex tool. Learning more about it, and how it works is never going to be a bad thing.
I dabble with some of this stuff and went to the Geek Squad because the computer was still under warrantee (think it is up this month). It wouldn’t start at all. I may take it back and see what happened.
