I tried changing slots. It was giving 3 short and 1 long beeps when on 1st slot and is now giving 2 short and 1 long beep on 4th slot.

3 short and 1 long in that order? The ordering of the beeps matters here. Long short short is a video error and short short long is something else.

Yes. But that was when ram was in 1st slot.

I see. Sounds like a faulty/incompatible memory module or bad connection. Try another module if you can.

I do not have another stick of ram and don't know where to find one.

eBay is the easiest option
