Couldn't figure out how to get the golden orb on my PIII-650 (my current system right now), so I tried for about 3 hours to boot up the computer, but to my despair it would keep freezing. I had a revelation in my sleep that I should try putting the HSF on and try again. Lo and behold, that morning, soonafter I put the Gorb on, it worked.
BTW, Stefan, if there was a Darwin award for computer makers, you would've been nominated in a heartbeat. Backwards?!? How the hell do you install a DIMM backwards? After forcing something in for more than a minute it should occur to look and see if the pins lined up with the slot....
