After adding 1 GB of RAM to my system, it restarts very often. Mother board - D865GSA Processor - Pentium® 4 Processor 511, 1M Cache, 2.80 GHz RAM - 512 MB (additional 1 GB added) If i remove the additional 1 GB RAM, the system works perfect. Could any of you help me to identify if the RAM what i am using is not good? or is there any other problem with my PC? Please help!
