Does it get past POST and fail to load Windows or does it not work at all after you turn it on? Check that all your modules are seated properly, and that you have the 1GB module in RAM slot 1 with the 512MBs in the other two slots. If it's still not working, put all the RAM in and do a CMOS reset:

1. Ground yourself by touching a metal part of the case, then unplug the power supply from the wall.
2. Short pins 2 and 3 of the CMOS reset pins, wait 10 minutes.
3. Return CMOS reset pins to 1 and 2.
4. Plug power back in and boot.
