Howdy! I'm a complete newbie round here, but was hoping someone could help me out. I have an HP-Compaq PC, running Windows XP, and currently have 256MB of RAM, so you can imagine the speed I'm whizzing along at... Anywho, I tried to rectify that by buying me some more ram, 1 lovely gig of the stuff. But I've had a few problems installing it! First I just stuck it in the first empty slot, computer didn't like this, just got beeps, which seem to have meant, "don't put bigger ram in this slot" So I tried it on its own in the first slot, turned computer on, and i get windows xp loading screen, but then the screen just goes black when the logon screen should appear. Both my old ram module and new ones are DDR PC2700. Any ideas would be much appreciated as hardware isn't really my area!
