I bought a Dell Dimension E521 two years ago. The specs are:
AMD Athlon 64 X2 3800+ 2x2,0GHz
Asus EAH4670 512MB
1GB RAM (2x512MB)
I decided to upgrade my RAM, it seemed to be the best decission to improve my PC. I bought two 1GB modules from Swissbit, but once I clipped them on the mainboard and turned the PC on, it wouldn't boot! The mainboard just beeped a few times and the fan ran. I almost thought I broke it, but when I took the new RAM back out, everything ran fine. I tried different RAM, too, but the same thing happened. If anyone can help me, please reply.
