My system was running perfect, now, NO POST

Question

My system was running rock solid yesterday.  Last night, I install this case mod, a cooler master musketeer- basically a fancy fan controller.  I noticed that after installation, my cold cathode lights would flicker- and my system rebooted itself once after idling for about 2 minutes in WINXP.  No problem, I thought, the new power supply system I ordered from newegg was arriving tomorrow, and it would solve the power drain that the musketeer was causing me.
So, tomorrow comes, and I get the new power system, an Enermax Noisetaker, 470W, supposedly a new top-of-the-line power supply.  It had some fancy stuff like "dual 12v rails" which had 16A on one rail for the CPU/Mainboard, and 15A on the other 12v rail for the graphics card, hard drives, etc.  
So I install this fancy new power supply, and my system boots up perfect.  Cool I think, as I fire up the game Battlefield:Vietnam.  I play this game for like an hour straight, no problem.  Then, as I am navigating through some menus within the game, the game suddenly crashes to desktop.  Wanting to duplicate this error again, I click on the Battlefield icon to restart the application.  However, the game does not even finish loading.  I get the EA games intro screen, and suddenly my speakers start making all kinds of loopy/static noise.  I attempt to ALT+F4 to close the game- but it doesn't work.  I press CTRL+ALT+DEL, but task manager does not popup.  Finally, I decide to press reset and then... NO POST.
No singal from monitor, no POST beep, nothing.  The bracket lights indicate that the system is failing on "Early Chipset Initialization".   Nothing I seem to do can correct this problem.  Things I have tried:
-Resetting the CMOS
-Removing the "Mustketeer" mod
-Reinstalling my old Enermax 350W power supply (which is the one I was using while my system was running rock solid; pre-musketeer)
-I tried switching the RAM to some old corsair sticks I had (sticks which also ran perfect before the mod)
-I tried one stick of ram; In all 3 slots
Edit: New things I've tried
The system is now barebones.  There is no hard disk attached, no optical disks, no floppy drive, etc.  Now, only the CPU, motherboard, motherboard LED bracket, power supply, and power/reset switches, and one stick of RAM.  Still, all I get is "Early Chipset Initializatoin" warning.
Edit 2:  Because my system ran so well before I installed the Coolermaster Musketeer and the Enermax Noisemaker, I'm betting that it was one of these components that caused my motherboard to DIE.  Which one do you think it is?  [STRIKEOUT]I am leaning towards the musketeer because my problems began when I installed it last night, whereas I installed the Enermax today because I thought it would solve the energy deficiency caused by the muskteteer.  However, I also feel as if the "dual 12v" design of the Enermax is largely untested with the AMD64, and feel as if the 15/16A rating for each 12v line somehow shortchanged my CPU and caused a malfunction.[/STRIKEOUT]  I am going to rebuild my system again, but I'd like to avoid this problem in the future.  So, given the choices, which would you guess the problem hardware to be?
Edit 3:  I guess this is a warning to anyone who happens upon this post in the future.  I have installed the Coolermaster Musketeer in my old AthlonXP system, and so far, it has caused no problems with my system.  As such,  I cannot prove that the Enermax Noisetaker EG475P-VE-SFMA has caused my system to die, all I am saying is that my system DIED shortly upon installing it.

i saw this, could this be a problem?

Hi,
We are very sorry about the problems you have experienced. We will do the best we can to get your problem solved.
Did you test them one module at a time? There is an incompatibility issue between 2 x 512MB PC3200 and K8T800 chipset. The K8T800 BIOS does not take some brands of ICs. If each module tests fine individually, your problem is probably related to that. If they fail testing even in one module load, it could be faulty modules. Either way, we will replace them. But we just need to know the root cause of your problem with your help on further testing.
In case we need to replace them, we will have to replace with 2 x 512MB modules too since there are some price difference between 2 x 512MB and 1GB stick and we can’t charge end user directly for the price difference due to reseller permit issue.
Sincerely,
Technical Support
