Performance counter string was not in the correct C # format

Question

Here is my code

float cpuLoad = 0;

try{
    MessageBox.Show("Running");

    //CPU Load
    PerformanceCounter cpuCounter = new PerformanceCounter();
    cpuCounter.CategoryName = "Processor";
    cpuCounter.CounterName = "% Processor Time";
    cpuCounter.InstanceName = "_Total";

    MessageBox.Show("Performance Counter Created");

    cpuLoad = cpuCounter.NextValue();
    System.Threading.Thread.Sleep(1000);
    cpuLoad = cpuCounter.NextValue();

    MessageBox.Show("Clock Speed Gathered");

    //Remaining Code
}
catch(Exception ex) { MessageBox.Show(ex.Message); }

I have an attempt to catch him, and here it throws an exception Input string was not in a correct format.

It prints the first two message boxes, and then throws an exception.

Now here's what I can’t get around, it works on Windows 7 Ultimate and Windows Server 2003, but it doesn’t work on my Windows 7 Ultimate colleagues. He used to work on his computer, but suddenly he was just stopped. The only difference in the next story was that he changed his Network.

Edit

Box 4 was updated this morning. But I have it on my machine too, so if it was a problem with the frame, why doesn’t it happen on my

Any ideas make me lose

Tested on his car

First failure cpuLoad = cpuCounter.NextValue()
