Did you take out the old memory and insert the new stick by itself?
Did you enter the BIOS and LOAD OPTIMIZED DEFAULTS
in order to set the new memory timings correctly ?

What OS are you running? If it's XP can you still boot with the old memory? If so right click on my computer hit properties. Open the advanced tab and at the bottom under start-up and recovery hit the settings button. Un-check the button that says automatic restart on system failure. Put the memory back in, reboot and this time the blue screen will stay open. Copy what it says and post the info back here. Actually you can do the same in Win7 or Vista. Just click on advanced system settings on the left side after right click on my computer.

Did you try both memory slots. It's possible your board just doesn't like that memory. I have some expensive (at the time) memory that will not boot up in a cheap mobo I have, but crap cheap memory works just fine.

Buffalo is excellent, and reliable memory.
I suspect that not all your drivers are up to date.
But mostly, you are still using inadequate memory...
YOu should be using only DDR400 PC3200, with no slower memory installed at the same time. Whatever memory speed you are using, it should all be the same.

The BSOD message it comes up with is

STOP:C000021a {fatal system error}
The windows logon process system process terminated unexpectedly with a status of (0x00000000 0x00000000).
The system has been shut down.

Hard drive failure?

Have you tried just with the new stick alone, and have you entered the BIOS setup to
"load the optimized settings" - this will set the memory timing.

If it still wont load windows, try running the memory tester, booted standalone from the CDROM.

PS these are standard troubleshooting techniques. Not sure if you tried it or not.
