Hello Everybody!I have an old Dell Dimension Desk top running XP Pro, that I rarely use. So just for fun, I ran an AVG scan on it; afterwords, the computer now takes 27 minutes (not kidding I timed it) to boot-up. First, there's a black screen which is on there for a very long time; afterwords, the blue XP screen which states "loading windows" comes on and it remains on for about 12 minutes before my desktop finally appears. Ive tried restoring it to two earlier times, did not help. Any ideas why it is taking so long to boot?Thanks,Charles1 person needs an answerI do too

Is there anything attached to the PC? If you disconnect everything except the mouse, keyboard, and monitor, how long does it take to boot up?How long does it take to boot up in Safe Mode?When you booted it up the first time -- before you ran AVG -- how long did it take to boot up?How long does it take to boot up if you first configure a clean boot environment? See:http://support.microsoft.com/kb/310353

Tried booting up in safe mode and clean boot, both still take over 20 minutes. before the AVG scan, i had it booting up in about 3 or 4 minutes. I did try F8 return to last configuration when it was working correctly...did not help.

Try System Restore. Go back two days (to the time when you could boot up your PC in 3 or 4 minutes. See:http://support.microsoft.com/kb/306084Also, consider uninstalling AVG completely (there is a special removal tool on their web site) and going with either Avira Antivir or Microsoft Security Essentials (both free).

Already did both,(one of the first things I did) still no help, AVG definitely deleted something

Have a look in the System and Application logs in Event Viewer for Errors and Warnings and post copies here. Don't post any from than more than 48 hours ago. You can access Event Viewer by selecting Start, Control Panel, Administrative Tools, and Event Viewer. When researching the meaning of the error, information regarding Event ID, Source and Description are important. A tip for posting copies of Error Reports! Run Event Viewer and double click on the error you want to copy. You will see a button resembling two pages. Click the button and close Event Viewer. This places a copy of the report into your Clipboard. Paste into the body your message. Make sure that this is the first paste after exiting from Event Viewer.I suggest you download Process Explorer.For further information about Process Explorer see here:http://www.microsoft.com/technet/sysinternals/SystemInformation/ProcessExplorer.mspx This freeware utility performs a similar function to the Windows Task Manager but it goes much further. In Process Explorer please add a Column. Select View, Select, Columns, Process, Performance and check the box before Start Time. Next select "Show Processes from all Users" and click on the column header "Start Time". This will sort so that you can see start with the earliest first. You may need to click twice or three times. The first item you see is smss.exe =Session Manager. You should then see a long list of items loading over a brief period of time. The boot process ceases on my computer with the loading of two AVG files (my anti-virus is AVG 2011. Before these two files is a uns.exe file which loaded this morning 2 minutes 20 seconds after smss.exe. Usn.exe is an Intel file so it may not be on your computer.How long does it take from smss.exe loading for the main files to load? What are the files arriving at the end and how long does it take for them to appear after smss.exe? Hope this helps, Gerry Cornell

you lost me on this one. Ive got 6 different viewer's beguinning with Application. Which one should I copy and paste here? Under Application's there are many warnings, as well as big Red X's for ACW_DE & "Load Perf"

In general terms the reports in the System logs tend to point to the cause of a problem. Warnings in the Application log tend to be symptoms e.g. a common report is that Internet Explorer is hanging. Knowing what applications are hanging can be helpful if the computer is generally sluggish.You are looking for a reason why the computer is taking so long to boot so you are looking for errors occurring during the last boot. Earlier boots are only of interest to see whether the error in the latest boot has occurred before, thereby confirming it is a continuing problem.Have you done any housekeeping to help the computer to perform better?Select Start, All Programs, Accessories, System Tools, Disk CleanUp to empty your Recycle Bin, remove Temporary Internet Files and other selected options. I also recommend you click on the More Options tab, System Restore and remove all but the latest System Restore point. Run Disk Defragmenter.Using the System restore option is most appropriate when your system is running slow and you need to increase free disk space on your C partition. If you have errors which might be resolved using System Restore to put your system settings back to before the error first occurred do not use this option.If more than one person uses the computer and they have their own user Log on you need to run Disk CleanUp in each user profile to remove all unwanted files.A better programme than Disk CleanUp is cCleaner but note that cCleaner will not handle System Restore points. Removing older restore points can be important if you have limited free disk space. cCleaner comes with a Registry tool. Do not use this tool as like any registry cleaner it can lead to the creation of very difficult to resolve system errors.http://www.ccleaner.com/download Hope this helps, Gerry Cornell

I'm pretty much out of ideas, GUZZLR. If booting up with a clean boot environment or in Safe Mode also takes over 20 minutes, something is really wrong, obviously! It's as if the AVG scan is a coincidental red herring and maybe you got yourself some malware after the scan.Assuming there is no malware, I would undo the System Restore you recently did, uninstall AVG, use their removal tool from their web site, and reboot. If still, no joy, one more System Restore (to the point before the scan). If that doesn't do it, a Repair Install (post back if you need guidance because having IE7 or IE8 can muck things up). And if that doesn't work, a Clean Install.If the booting never completed, I'd suggest chkdsk /r. ____, what do you have to lose? Before attempting a Repair Install, try chkdsk r.Reference:http://www.avg.com/us-en/download-toolshttp://kb.wisc.edu/helpdesk/page.php?id=5097
