Try running Prime95.

Just Google for CPU stress test.

There is virtually no such think as a flakey CPU...
they either work or they don't.

About the only way to have "flakey" CPU performance would be
by inadequate cooling or overclocking

Prime95 has a torture test option, and it does a math calculation
with a known answer. It compares the computed result, and the program
stops with an error, if a problem is detected. It exercises the
CPU, the Northbridge, and the memory. If a problem is found, one of
those three could be at fault. It does not exercise the video card.

This one is multicore compatible. When asked to "Join GIMPs?", say
no. The custom dialog only needs to be adjusted, if you want to
reduce the amount of memory the program is prepared to test.
I like to see it run error free, for at least 4 hours or so.
