I would still venture to try a reinstall of SP2 again
or at minimum make sure that you have at least Service Pack 1a installed and check for other Critical updates
If you decide to Reinstall Service pack 2
Ensure that all hardware drivers are up to date
Backup Important files and documents just in case
Know how to get out of trouble in advance just in case something goes wrong
http://support.microsoft.com/default.aspx?...=windowsxpsp2kbWouldn't hurt to run an Online Virus scan just for a double check
Do one at Housecall's>>Set to Autoclean
http://housecall.trendmicro.com/Run updated spyware checks with Spybot and Ad-Aware
Restarting in between if any bad guys found
Clean those temp folders, can't remember if I directed you to Windows CleanUp!
You should regularly (At least once every couple weeks)
If you would like to try this free utility to do it for you
Download and Install this small program
to help clean your temp folders,cookies,prefeth folder, etc...
Windows CleanupOpen Windows CleanUp,
Click the CleanUp button, let it finish scanning for files and then Log off and back on
or Restart your computer
Defrag your Hard drive ahead of time>>Best done in safe mode
Restart back to Normal mode afterwards
If your updating to SP2 online It wouldn't hurt to disable your AV temporarily
I would also disable any third party download program>>Eg... Getright
And ensure that all other users are logged off
===If your on Dialup and need to order the CD, I believe you can still order it free from this link>>I'm on Cable and still ordered the CD, nice to have around
http://www.microsoft.com/windowsxp/downloa...us/default.mspxLet it download and install>>Even if it appears to hesitate at times
When it's done
Restart when prompted
Go back to Windows update and see if there are more High priority updates
Restart if prompted again
After your back in Windows run Windows CleanUp! again
Log off and back on
This should help to have a clean install of SP2
If it doesn't help than I would think it's more of a Wireless>>SP2 issue
That link has many suggestions
But you did have many problems in your Hijackthis log...
