Event Viewer has been showing warnings for Boot duration for several weeks. Typical Boot duration over this period has ranged from around 130000ms up to around 300000ms.

Any assistance as to why it's so long and how to fix it would really be appreciated.

Please post pertinent content of EV error, as reflected.

Module, event number, source and the detail for a given error...should be included.

What does the boot time translate to in minutes?

In response to Allan, the boot time above of 251398ms is 251.398 seconds, so around 9 seconds short of 5 minutes. That's if I've understood it correctly, which I probably haven't.

:) I really didn't want the math. I was hoping you'd boot the computer and see how long it takes for the desktop to load. If you have a chance, could you do that please - from power on until the desktop shows and then until it finishes loading and can be used. Thanks.

From power on to when I'm asked for my password takes about 2 minutes 20 seconds. Then about 20 seconds until the desktop shows, then about 15 seconds until it's fully functional.

Just to fill you in on a bit of history. It was taking several minutes from entering my password until the desktop finished loading, but this is much quicker now. The culprit appeared to be Avast free anti virus. After a clean install yesterday this time is now much shorter.

However, there is still the problem of a long boot time from power on until I'm asked for my password. As I said in the first paragraph, this time is typically now around 2 minutes 20 secs.

Help would still be very much appreciated.

I don't see any problem with your current boot time.

Thanks for your responses Allan. However, I believe the boot time is very much a problem. Indeed, the most recent boot time of just over 150 seconds has been flagged as critical in event viewer.

So I say again. Can anyone provide any help or guidance as to how to rectify this?

You really should stay out of event viewer. It can drive you nuts. 2-3 minutes is not a very long boot time. But okay, if you insist on playing around with it here's what you do:

Open msconfig and on the General tab choose "selective startup" (uncheck all three items) and reboot. Does the problem still occur? If not, start adding items back to msconfig one or two at a time, rebooting after each change, until the problem reappears and you'll have identified the offending process. This is clearly a time consuming procedure, but it is the best way to determine if some process loading with the system is the cause of your problem.
After you've isolated the cause, do not use msconfig to permanently disable the process. Instead, if it is a service go to START - RUN and type: services.msc (then press enter) and disable the service OR, if it a program, you can download & run a simple app such as Mike Lin's Startup Control Panel (http://www.mlin.net/StartupCPL.shtml) to enable, disable, or otherwise manage startup programs.

Just to let people know what I did to fix the slow boot 'problem'. After trawling the internet for a solution, I came across an interesting topic (see link below). Apparently Vista has its own built-in Boot file defrag but it only operates when a PC is idle thus, for many, it will never see any action. The 2 commands shown in the link below invoke this defrag. After using it, my boot time from power on to log on password request has shortened massively to 55 seconds. There are also a number of other Vista tweaks recommended at the beginning of the topic:

http://forum.notebookreview.com/microsoft-windows-xp-vista/166532-nbr-vista-tips-tweaks-guide-79.html#post2737834

There's also another tweak I found which supposedly shortens boot time, but it involves more messing around with the registry and multiple reboots, as follows:
