Odd CPU usage problem, above 100%

[BuddyCole]

Just last week I started having a services.exe error shutting down my computer, and boy did I think that was a big problem. Well, now I can't even use my computer when that doesn't happen, because my cpu usage went all wonky on me. As of last night my CPU usage was normal, and when I woke up there was a bluescreen. Happens every now and then on this piece of crap, so I didn't pay mind. Restarted...bluescreened within the first two minutes. Same goes for the next 3 times I restarted.

I go in safe mode and it still happens. I find out that my CPU usage is through the roof, it was at 140% then back down to 5%, with absolutely nothing being used. Also, the graph itself looks a little weird, see for yourself:

When I tried to run a game, the PF usage (I don't even know what that is...) jumped up to 1.58 GB! This is truely odd. I cleaned off my memory stick using the eraser trick and re-slotted it, to no avail.

What the hell? How did it go to 140%?

Either you run WAY too many programs at once or you have something wrong with your CPU

Hey,

140% CPU usage is a bit funky. I have never seen that before. I recommend format and reinstall.

Hope that helps.

What process is using that CPU time? Sort the processes tab by the CPU column and see.

The number goes above 100% because you have a dual-core processor and you have set the task manager to show only one graph for two processors.

Turns out it was a the trojan known as Backdoor.Rustock.B, it's been crashing my system constantly the past two days with the same problem every single time. I took an hour reading various cures and found the easiest one was to download rustbfix and run it in safe mode. Simple as that.
