Windows 7: Slow boot up sometimes, other times fast

Slow boot up sometimes, other times fast

I'm new here and in need of help. I installed Windows 7 pro 64 bit by upgrading an XP Pro machine, ie. a clean install with a windows.old directory. After installing all of my programs, sometime when I bootup first thing, it can take 5 minutes to reach my desktop. Last night I ran msconfig and disabled all of the startup, and booted up in 45-55 seconds. I slowly enabled each of the items in startup, and now with all items in startup enable, it still boots in 45-55 seconds. I don't understand why sometimes it stays at the black screen with the windows logo for 4 or 5 minutes with the hard disk trashing, and other times it boots up quickly. Any help or advice would be appreciated. Thanks.

Welcome to the Forum

If you try a clean boot, you may be able to discover the cause of the problem

Another part of the problem is that a new install takes time to adjust, setting, indexing etc. I think that if this is a new install, you should wait a while before taking any action.

Thanks Richard, I appreciate your feedback. I have to admit my installation is just about two weeks old, but I didn't think that it would take this much time for the system to settle in. I did perform a clean boot per the MS instructions, I just disabled the startup items. The system came up quickly. I therefore thought that one of my items in startup was the cause. I was very supprised to find that after I enabled them all again, the system came up quickly. I shut down for five minutes and restarted, and all was fine. I'll see when I get home tonight after leaving the machine off for 24 hours how it boots up. Again thanks for your help and advice.

Mark, I am happy too, your computer is working and it was real easy for me, too. Probably a start up item was not working properly, turning it off reset it.
Good luck.

Well, I don't know what to make of this. This morning it took 4 minutes 50 sec. (Yes, I'm timing it). Yesterday once it took 2 minutes 30 sec. and another time 50 seconds to boot up. I haven't installed anything, just reading email and web browsing. I can't understand this large variation in boot up time.

Apparantly the slowness is caused by one of the services that were disabled. Try the clean boot again. This time wait a few days between adding the additional services. I would wait a week, between additions.

Post a shot of the msconfig startup tab, and if you have AVG, kill it with a removal tool and install MSE.

I've experienced the same situation and believe I discovered the answer. If you have Windows Update set to automatically update your computer, the boot time will sometimes be extended because you're system is "configuring" or installing new updates that have been downloaded during your previous session. Next time you experience a long boot time check and see if a new update was downloaded and/or installed.

Yes boot time will slow if another process is working at the same time. I have not experienced a slow boot, as I boot only about once a week. I have expereinced slowness, surfing or while performing other functions if a download is being performed or my A/V is getting an update etc.
