Only ONE Core working (Q6600)

Hey Geeks!
As you can see in my signature, I have an Intel Core 2 Quad Q6600.

1st :
This morning my CPU usage started to get to 100% everytime I did anything like clicking on a link in the IE or something like that.

2nd :
Normally you can change the taskmanager to display either one diagram for all CPU cores, or one diagram for each core seperately.
I can't change that anymore. It's like Windows doesn't recognize my Quad CPU.

But sometimes everything works as if everything is normal.

What's happening here?

PS: Screenshot of the task manager after clicking 2 links attached.

PPS: Opening Paint makes the CPU graph go to 100%...


EDIT: It seems as if only one core is working of my Quad Core. Renamed the Topic Title.

If I scroll on a page in the Internet Explorer, the Internet Explorer takes most of the CPU and the usage goes to 80%!
But svchost takes a lot of it too and it goes up to 30% if I don't even do anything.
Hope this is enough information for you.

EDIT: When I clicked the button to post this message, the usage went up to 70%...
Oh, and I just noticed that I uploaded my entire desktop :) Sorry for that large picture :)

When I go to the device manager -> computer, I see ACPI-PC standing there.
Shouldn't it be ACPI-Mutliprocessor-PC?
How can I fix that?

EDIT 1: Oh, and I only get a score of 6868 in 3DMark06. That is nowhere near to the result my computer should get!

EDIT 2: The device manager shows, that all 4 cores are being recognized. There are four entries named "Intel® Core™ 2 Quad CPU @ 2.40GHz"

L2SILukas,
I have not replied to you because my first thought is malware, but you have been through that here just a few days ago.
When you say "reset BIOS" what do you mean?
Did you move the jumper and remove the battery?
Look in your BIOS for multi processor, or multi core support enabled.
Do you have the manual for the Motherboard?
Have you been changing things in control panel because you would like to change the language that is displayed?

You only have 1 computer, not multiple computers. So that is normal.
You have 4 processors.. so it will show under processors. I can disable a single processor on my duo.

Under Device manager.. look at the Processors.

You can right click on each to see more information.

Yes, thats what I mean with resetting the BIOS.
I've already been searching for an option named like that, but I'm not sure what one entry means:
This is from the Manual, not from the BIOS.
Max CPUID Value Limit [Disabled]
Setting this item to [Enabled] allows legacy operating systems to boot even without support for CPUs with extended CPUID functions.
Configuration: Options [Disabled] [Enabled]

I don't know what that is set to, but I'll take a look at it now.
Also, I didn't change a single option in the BIOS.

My problem just started from one day to the other.
And I know that I can't change the language of Vista right now, because I installed SP1. I can change that after SP1 is released for all languages...

EDIT:
These are all the options listed under "CPU Configuration":
Default CPU Ratio [Enabled]
Max CPUID Value Limit [Disabled]
Execute Disable Function [Disabled]
Enhanced C1 Control [Disabled]
Virtualization Control [Disabled] <-- This option is not changeable (it is gray and I can't choose it)
CPU Internal Thermal Control [Enabled]
Intel® SpeedStep Technology [Disabled]

EDIT 2: All processors are activated.

Ok, when I go into the device manager now, go to Computer, there now is ACPI x86-based PC (ACPI x86-basierter PC). If I right-click on that and click on Update Drivers, select "I will search for drivers" or however this is called and then click on "Select drivers from a list", I can choose between: ACPI x86-based PC and ACPI-PC (Advanced Configuration and Power Interface)

Is there anything that could be the problem? Or is anyone out there that had the same problem and can tell me how he solved it?

I did as directed and still nothing has changed.
Any other ideas?

EDIT: BTW, I had the latest BIOS version and chipset drivers.

I took out the processor to apply my new thermal compound and I checked if I can see any scratches on it, but it looks alright...

Still nothing has changed (Oh, but my temps did :) )

If you updated your drivers through windows you may not have the correct drivers contact the Intel site to download the proper updated drivers for your processor. I have found that the investment for a driver update site is worth the money 10 times over

Ok I finally got it...
I reinstalled Vista, but I had a freeze while doing that.
Nothing worked, but I got an XP CD from a friend, installed XP, but somehow it did not have an Internet Explorer and I could not connect to the internet.
I couldn't play music as well because WMP didn't work, but everything I had to do was installing vista.
Now all 4 cores are working. :)

PS: I formatted the XP HDD, because I would not use it if nothing works :) So no Dual-Boot for now.

EDIT: Oh, I installed the english language pack now, so I can update to SP1 and use it :) Vista in english, finally!

Given that you have already updated your BIOS and chipset drivers (although with the new install, you may want to do it again if you haven't already, direct from the ASUS or intel website). Do you know why Vista setup froze when you went to reinstall? At this point I am starting to think it might be a motherboard issue, and you might want to get a hold of ASUS to get some help troubleshooting, but if it's worked out, that may be a little extreme. Hope everything is working! :)
