I think you should go tothe security section of this fourm and post a hijackthis log ,
get hijackthis here and post a log in security section .
Here's how to post a Hijack This log - the whole spiel, with (hopefully) every eventuality covered... :

Go to http://www.majorgeeks.com/downloadge...8baee6434cfc13 , and download 'Hijack This!'.
When downloading, choose "save to disk" and NOT open!

Now this download is a *.zipfile, which means you need to decompress it with a utility like WinZip

Many downloads come in the shape of a compressed file, so it's an indispensible tool, really.
It has an evaluation version which you can use for a month or so
Here's a tutorial. It's extremely easy to do.

Now create a new folder for it, C:\Hijackthis, for example.
After unzipping the file to C:\Hijack This, you'll end up with the file itself, which is Hijackthis.exe, and that's the one you'll need to doubleclick.'

When the program launches, hit the "Scan" button
When the scan is finished, the "Scan" button will change into a "Save Log" button.
Press that, and save the log anywhere you like.

Now if you doubleclick the log file, does it open in Notepad?

If so, go to Edit > Select all, then to Edit > copy.
Now you've copied the entire text to the Windows Clipboard (this happens behind your back.)

Next, go back to this forum thread, and click "Post Reply".
In an empty area click your RIGHT mouse button, and choose 'Paste' from the context menu.
And voila, there's your Hijack This log.

NOTE: Should the log not open in Notepad by default, do this:

. Highlight the logfile by clicking on it once
· Hold down the shift key and then right-click your mouse
· Select "Open With" from the menu
. Pick Notepad.exe.

Be sure to check the box, "Always use this program to open these files".

· Click "OK" and you are all done!

I had a computer that had similar slowness issues and it wound up being a combination of the video driver and the mouseware driver from logitech. Since you say it doesn't do this in safe mode, I'd definitely disable all the start up items, i.e. Direct CD & Logitech Mouseware and possibly uninstall your video card drivers and just see what happens.

No, you were suppost to go to the security section to post the log ,

Edit : i seee you posted in the security section ,so no need to move this one!

Disabling those items one at a time might let you pinpoint the exact problem.

The Plug-N-Play behaviour could be due to a conflict between PNP and some other application or process. In other words, PNP itself might not be the problem; by disabling it you are eliminating the conflict, but you're doing it by disbling the wrong half of the conflict.

Is it really nessary to have two AV programs running?

Not only not necessary, it's not recommended either- they can conflict with each other.

Thanks to QT for you ideas on start up items and thanks to DMR for your ideas on conflicts with plug and play and not necessarily plug and play itself. I disabled all start up items and left plug and play enabled and the system ran fine. I will now go through the list and find out what is causing the problem and conflicting with plug and play. Thanks for all the help. :cheesy:

Cool. Just re-enable each item one at a time and you'll be able to narrow it down to the offending item.
