Sudden shutdown p4c800 during high load

Whenever I overload my system (100% CPU) the machine shuts down without
any warning.
To track down the problem i tried the following:
- Changed Powersupply
- New videocard
- New memory
- New CPU-cooler (zalman)

No other cards are used in the system.

The problem is still there.

The CPU-temerature is constantly 48 degrees.
When I overload it, it becomes around 60, but not higher...

Anyone who had te same problem and maybe a solution???

Or should i try something else?

HELP!

Reasons it could shut down:

1) THERMTRIP on CPU has triggered. When CPU hits 135 degrees C,
the computer will shut off.
2) Power supply internally detected fault.
3) Overloading +5VSB will also cause the PSU to shut down, even
if there is no fault detection capability inside the PSU. The
+5VSB not only runs the motherboard when the computer is
sleeping, it is also used by the supervisor circuit inside
the power supply. Shorting out that supply will cause the PSU
to stop. Based on your problem description, this is not likely
to be the problem.

To help you, we need to know:

1) CPU type and speed - P4 Prescott 3.2GHz 550 or 660 or whatever.
The SL code (SL123) or order code are precise specs too.
2) Video card brand and type - some of these take 70 watts of power.
3) Power supply brand and model number. Or, alternately, list the
output power rating: 3.3V@20A 5.0V@20A 12V@20A +5VSB@2A and so
on.

Since you did not describe the problem as happening while gaming,
then perhaps it is not the fault of the video card. For a P4
based system, I recommend 12V@15A minimum output rating, as the
processor is powered by the 12V supply. How much more than 15A
should be provided, depends on the video card, and how many hard
drives etc.

Since you likely won't be posting back, you can work this out for
yourself via this site:
