okay let me start off by saying i dont really know much about computers, and recently i bought a 1gb ram from kingston to install in my computer. I used the newegg memory search and found a compatible ram for my system. It works well once in a while but sometimes if i tried to start a game it would give me the blue screen of death, Saying that it needs to prevent damage from my computer, It also stated that i need to disable shadowing or caching from bios. This doesnt often occur. It usually happens 1/8 of the time. Also the ram i bought was a 1gb pc2 - 5300. And my old ram which came with the pc has 256x2 512mb pc2 - 3200 what can be the problem?
