My disk is constantly solicited

[Boleslaus]

I recently updated my cpu, my card and I have reinstalled my OS.

I spend an Athlon 64 3500 + to an Opteron dual core 4800 + @ 2.8 GHz OC.
In a 7300GT to a HD4850.

Since the reinstallation of the OS, my HDD is always active ... I thought it was Vista so I am back to XP but idem whereas before it did not! In fact, I see it as a diode red box flashes when the drive has access to its contents. Before that it was blinking when a task was in progress or a diverse and stopped it when nothing was running. The unsightly was low but there is no stopping ... I wonder if it is not the new dual core cpu. It is therefore the installation of the OS and yet I see nothing special in the task manager.

Do I forgot to install something for this specific cpu (because from the OS and drivers, I will not install anything else)?

Thank you for your help because it draws the eyes during movie watching or should I switch off the LED, but if I could do otherwise ...

Thank you for your help.

Now with Vista and XP SP3, there's indexing of your permanent files

Otherwise, what is the exact difference between this log and the Processes tab of Task Manager of Windows?
