PSU or heat problems?

My specs:

AMD Athlon XP2400
Gigabyte KT7 board 8x AGP
512 MB PC3200
2 Hard drives
ATI Radeon 9800pro
SB Audigy
Thermaltake XaserIII case w/cheap 400watt PSU
----the case has 7 case fans (4 in - 3 out)
----running Thermaltake Volcano 5 HSF
----Ram has heatspreaders

Help! My computer shuts down when I play games. (the heaviest load I put on it) I then have to unplug my power cable to restart it. It acts as if it is overheating, but the CPU, Ram, is cool to the touch. Sisoft Sandra reports the following temps (no load):

*Board Temperature : 45.0°C / 113.0°F
*CPU Temperature : 46.0°C / 114.8°F td
*Power / Aux Temperature : 41.0°C / 105.8°F td

The PC shuts down when the CPU is around 56c! I am unsure what the PSU temp is when the system turns off. It happens more often when the room is warmer, than it does if its cool. And sometimes if I have the side off of my case it will not shutdown. I have reapplied 3 types of goo between heatsink and processor. I am running Artic silver ceramique at the moment. The only hot exhaust from the case is from the PSU. The Case is in a computer hutch, with 100% open front and back. (shouldn't be the trouble). Also my chipset's 40mm fan died, and I need a new one. I bought the new case Thermaltake XaserIII because of this problem, thinking it was heat.... but I still have it. Could it be the PSU bad? or not enough juice? Or should I junk the old Volcano 5 and get a new Fan and heatsink? Please help, I am tired of getting into a major firefight in FARCRY and having the system turn off....

Thanks... ROGUE

    Is your computer beeping before it shuts off. Usually most new bios will send a few beeps to the mobo when it's a heat issue before it shuts off.

    Could be the PSU though how dusty is it where the computer is?

    Rogue,

    It cannot be because of heat with all those fans and 56c is nothing at all. My little mobile is priming at 67c without restarts and i have no caseflow at all.
    Let's try a new one that i have done before while troubleshooting. Well, first of all, check with Goldmemory or Memtest86 so that your memory is up to par and not faulty. Overclock a little more so that the temps is going over those that you have , but in idle and stay in the bios. Look in the health section and watch both voltages and temps. That should give you a hint if it's the OS or hardware that is bad.

    No beeps at all... acts as though someone pulled the power cord out of the wall.

    PSU is very clean, all components are... I use filters on all my intakes.... (took them off to increase air flow, but still shutsdown)

    Thanks for the ideas, but, this is my first system I built without a floppy :P and can't run either of those memory tests... any other tests I can run from windows or a CD?

    Also, I overclocked the PC, to 2100mhz, tonight, before OC at idle CPU was 40c... after OC only got up to 44c. All my voltages were constantly fluctuiating 0.01 - 0.1 volts....

    why dont you just pop in a floppy drive to do the tests and what not?

    There are no memorytesters that's windowbased. We can't find out if it's memory related or not then. You can burn both memtest and goldmemory to a bootable cd though. That's what i use. If you have a cd-r that is?

    Hey guys... I put a new chipset fan on my motherboard and have had no more problems! Thanks so much!
