Hi, I'm having a problem with my old pc. I'm trying to get it running so I can have an extra computer. I booted it up awhile ago and it seemed fine. So I ordered some ram and a new hard drive. I haven't got them yet but I took out the ram to see what kind I needed. I put it back and all looked fine so I just left it. But when I tried to boot it today nothing showed up on the screen. I tried reseating the ram but that didn't work. I tried two different displays and neither showed anything. I tried another power supply also. I noticed that on the original display one of the prongs had broken off but I remembered that it had been that way for awhile. Maybe the prong is stuck inside it but it worked before. It seems to boot fine, all the fans running and when I put the Windows XP cd in the cd spun as usual. There is one sound that is missing from the regular boot up so I have a feeling that there is something wrong with the hardware. I have no hard drive plugged in because it doesn't work and that's how it was before. ANY help would be useful, if you have any questions I'll answer them as best I can. Thanks for any help.
