Watchdog test in Windows XP

Question

I want to test the watchdog in my system. How can I totally freeze the Windows XP, in order to let the watchdog to perform reset?

I tried the "fork bomb", but it didn't help.

I don't care if OS will be damaged or destroyed. This is test station, so I can restore it quickly.

Thank you in advance.

Create a new process which just wastes CPU cycles, something like:

int main()
{
    for(;;)
        ;
    return 0;
}

and give it realtime priority from the task manager. The system will hang.
