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