After PC is on it starts to get sluggish to the point of becoming unusable until reboot, and all is fine after reboot until it slows down again. It will start out by just seeming a bit slow, then even things like typing get delayed or opening or closing windows. A few times it got so bad it appeared that the screen wouldn't even refresh.

PC is Vista 64 SP2 with 8GB RAM. I see no new or suspicious processes or resources; disc activity, CPU, and memory usage seem normal. The problem does not seem to occur with any particular application.

What I've Done:
HP hardware scan - ok
Everest scan - ok
Norton 360 complete scan - ok
Malwarebytes scan - OK
Rootkit Revealer - app crash every time I run
Sophos Anti-Rootkit - found hidden files, all seem legit

How much time does it take for it to get sluggish?

Download, and install SpeedFan: http://www.almico.com/sfdownload.php

It seems to slow down after a couple hours of use. Last night I booted before I went to bed and left it on - this morning it was still fast. After using it for a couple hours (off and on) it already slowed down. So it seems like it's use and not time the machine is on.

I did the Speedfan thing but forgot to post the results. Right now it shows core at 37C with CPU at about 40%. It says fans are at 0 rpm.

Everest reports temps of 36 for the cores and 48 for CPU. It also reports 107C for motherboard. I know this is not accurate - after booting cold MB read at 95C. It also shows 1619rpm for chasis fan and 993 for power supply fan.

with CPU at about 40%

Does the above number grow with time?

Download Process Explorer: http://technet.microsoft.com/en-us/sysinte...s/bb896653.aspx
Unzip ProcessExplorer.zip, and double click on procexp.exe to run the program.
Click on View > Select Colunms.
In addition to already pre-selected options, make sure, the Command Line is selected, and press OK.
Go File>Save As, and save the report as Procexp.txt.
Attach the file to your next reply.

The CPU typically doesn't go very high unless I'm running a lot at a time, such as processing large files in Photoshop.

I have process explorer already installed but I'm going to hold off on posting the log, I may have found the way-too-obvious answer. The plugin container for Firefox was crashing several times a day. When I use Photoshop or similar application I listen to streaming music and was using FF for XM radio. So to avoid FF locking, I installed Rhapsody last Monday... just about the time things started slowing down. I turned on Rhapsody this morning and just turned it off for a reboot and the PC sped up again. Coincidence? I'm not sure at this point but will test this theory later.

I'll report back here if/when I'm convinced Rhapsody is the culprit. Thanks for your help.

I suggest, you disable plugin container altogether: http://www.technogadge.com/how-to-stop-fir...er-exe-process/
