I went out and bought some RAM, came back, put it in, and it wouldn't work. The computer emitted a longer-than-normal beep upon starting, and wouldn't do anything. It's a (as far as I can remember)
A8N-SLI nforce4 motherboard, the ram I currently have in it is two 512 Kingston DDR PC3200. The RAM I bought is a Comstar (quote straight from the package) "PC3200, 1GB, DDR400, 184-Pin". I've tried putting it in with the other two, replacing one of them with it, but nothing works.... dunno why, cause as far as I know it's the same type that's in there now. Any ideas?
