Hi everyone. Today I just bought my self two memory stick of RAM (1gb each) to give my PC a little boost, but when I plugged them in and turned my PC on, I noticed only 1 was working, so I unplugged and re-plugged both to be sure and still have the same problem. I made a quick search on google to check would could be happening and I figured out my PC has only one Memory Slot available.

Any help would be appreciated, ~ SalokinX
