So I got this HP Pavillion 566mhz, 64mb SDRAM computer from my grandma - Her old one. Probably only about 2-3 years old so it should be running fine (which it had been for like a month). Well, it was and then Monday I went and got a wireless adapter for it so I could get internet up in my room. So that's been giving me problems and the machine was running 98 so I thought that might of been the problem, so I installed XP on it (I've also been wanting to update it with XP). So I install XP on it and then realize my mouse isn't working...odd. So I turn the computer off, unplug the mouse, plug it back in, hit the power button and....NOTHING. Doesn't turn on. So I thought "What the hell now?" So I checked all the connections and tried again and nothing. So I thought maybe the powersupply died. So at 5:30 this morning I got up, grabbed an extra one I had and hooked it up and it worked! Wooohooo! So I get the computer turned on, still no mouse working but I needed to print something out so I just used the keyboard. Well, I had to re-install the printer and I forgot to hook the CD Drive back up (as far as power goes) so I turned the computer off, plugged in the CD Drive, hit the power button and...NOTHING! It didn't turn on. Checked all the cables and whatnot, tried again and nothing. So now it seems like I got 2 dead powersupplies somehow and no clue as to WHY. This sucks.
