Weird processor mounting screw keeps turning but isn't stripped

Hi, people.
I was just trying to remove a Slot 8 (Pentium Pro) heat sink, and was having difficulty.
It's an HP NetServer LD Pro Server (Model 6/180)--a monster that weighs about 60 lbs (the motherboard is about 15" x 10¾"). It was purchased at a live auction, and given to me by a co-worker.

There's a processor board that has 2 mounting screws.

Well, they loosen, but then seem to tighten after 3 turns or so. Then they feel looser, then tighter. Then, clockwise, they tighten right back up. I'm pretty sure they're not stripped. There's a funny round fastener I'm unfamiliar with on the other side--it doesn't turn, when I loosen the screw, though.


I can't figure this thing out.
The Pentium Pro (180Mhz) works. I'm just trying to get experience before trying to pass A+ tests scheduled for the end of the month). I might also blow the dust out of the heat sink...it was bad....real bad.

With a small flat blade screw driver pry under the head of the screw upwards while you try to remove with phillips screw driver, just a little pressure upwards should get the screw started. It might take you a couple of turns to get the flat blade under the head of the screw.

while unscrewing it, push it out from the otherside

The screws' threads are probably messed up from age, and they are skipping a thread when near the end. Do as suggested above. Those fasteners on the backside appear to be pressed-on 'nuts' not intended to be removed.

After sleeping on it, I gave it another try.

I tried using an al (try checking the spelling of that one using google ! )--one of those sharp-pointed tools like a punch, to push through from the other side (like you said, darren0000)...it still didn't go through......but, I noticed it giving a little. So, I just pulled the whole processor board out, and it came right out, mounting screws still attached--there not supposed to come out, I guess.

So it's good to keep in mind (sometimes), if it's not going the way you think, you're probably making it harder than it really is!.

That release lever rather stiff: it was even creaking a little like a rusty screen door (could have been the first time it has been released since the Pentium Pro was first installed).

Thanks, guys!
