System failure

[Frisco K]

I have a big problem, and I suspect I am not the only one.
I built a system based on a P5AD2-E Premium Asus motherboard.
It functions great as long as it is not used for gaming - I play BF2. That is when the system crashes and I get the notification ?System failure due to CPU overclocking?
My problem is that the system is not overclocked.
The JumperFree Configuration is set to AI Overclocking ?Standard? and Performance Mode ?Standard.
Nevertheless, after the problems started I changed the AI Overclocking to ?Auto? and the Performance Mode to ?Auto? to see if it would help, to no avail. I did returned them to Standard settings, where they are now.
I already changed the power supply from an Antec True 430W to an Antec True 2 480W thinking that it could be a power supply problem, but the problem persists.
I am looking for any ideas for what could be causing the problem and how to solve it.
Thanks

My system is built as follows:
Case: CoolerMaster Wave-Master
MOBO: Asus p5AD2-E Premium, Bios Ver. 1005
CPU: Pentium 4 550 3.4 GHz.
Power Supply: Antec True Power 2 480W
Memory: Corsair XMS Pro DDR2 675 PC2-5400
HD: WD Raptor 74GB
VideoCard: BFG 6800GT

If you go to cmos and set bios defaults, do you still have the problem?

Yes, I still have the problem.
Further research and input from readers indicates that it may be a high CPU temperature issue. The CPU is idleing at 65 C
I will be changing the heatsink I have on right now, Thermaltake Silent 775, for a Thermalright XP-90C.
I will keep posted about the progress, hopefully by Saturday.
