I've developed a problem with a PC i was fixing up. I was trying to install xp and was hitting a few problems which looked like it was the HD. I removed it, hooked it up to my Pc and ran the diagnostic tools on it, formatted it and all was good. Put it back in and got a lot further with the instal but hit another problem, this time I think it was to do with the xp cd. Anyway turned it off, removed one stick of ram and the graphics card to plug into another machine I was testing. That was fine, but when I put it back in I got the dreaded long beeps when I try to boot up. There is also nothing on the screen.
Here's what i've tried so far. I've put the ram in another machine and it works fine, i've tried different ram in this machine and i get the long beeps. I've tried using the onboard graphics and another older graphics card and the problem is still there. I've tried a different power supply, but it still beeps.
It seems to me that its something to do with the ram, perhaps i've damaged the slots somehow?
