I have already told you about a weird problem that I had with my computer  
which is able to run heavy programs without problem for hours upon hours, 
but simple programs such as cal.exe, notepad, task manager, regedit, 
freeze. The CPU is Athlon 64, X2 3800, s.939. problem disappears when 
using only one of the CPU cores.

I already ruled out the possibility of a software/driver problem, and I 
now suspect that the problem is with the CPU.

I need to find a utility that tests the CPU thoroughly. There is no need 
for a burning test (heavy load test), but rather for a tesat cat checks 
various instructions to see if one of the less commonly used ones freezes 
the thread.
