My Dell Dimension 1100 desktop PC is running Windows XP and has 2 x 256MB RAM modules installed, with a 2.8GHz Celeron processor. The MB has E210882 written on it. I have tried upgrading to 2GB of RAM by inserting 2 x 1GB PC3200 184 pin 400MHz DDR DIMM's. However, when I boot up the system with the new RAM in, I get a series of POST beeps and no video display and nothing else happens. The PC works fine when I put the old RAM back in, however it is slow and I really need to upgrade. Any ideas what could be wrong?
I got the RAM new on Ebay - Item number 350073146245. It is non-ECC, non-parity, unbuffered. The code numbers on the RAM chips are SAMSUNG K4H510438E-GCCC. The label on the module says "1G DDR 400 PC3200 AE25D1284 M40963 0824".
