How do I remove CPU-Heatsink-Fan from mobo

[kev25]

My system:
Intel Pentium III 1GHz 133MHz FSB, 256K Cache
SY-7VCA-E Soyo Socket 370 ATA 100 ATX
TOSHIBA 16X DVD
Plextor CD/RW
Western Digital 40.GB 7200 ata100 HD
Western Digital 20.GB 7200 ata100 HD
ATI ALL-IN-WONDER 128 PRO AGP 32MEG
SOUND BLASTER LIVE! VALUE
Mitsubisi 19" CRT
USB Linksys Wireless-B Network Adapter
Win98se

Either my mobo or my processor is dead, perhaps both. When I turn on the computer, I get no beep and no screen, just black. The fans run and the indicator lights go green on my drives, but nothing happens. I can't access the Bios. I disconnected all drives and cards except for a small working vid card, again, no beep and no available Bios entry. Putting in a Win98 startup disk makes no difference. I replaced the 6 year old power supply yesterday with an Antec350 to rule out power supply problems. New PS makes no difference. I do know the old power supply could have fried the board and cpu. Anyway, I'm about to purchase a Tyan socket 370 mobo from NewEgg for $44.00, and I would like to instal the old P3-heatsink-fan unit from my Soyo to see if it works before I spend more money on a new P3.
Question: How do I remove the CPU-heatsink-fan unit from my Soyo board. Do I have to separate the CPU from the heatsink in the process? My sister wants THIS, or very similar system in working order, so please don't suggest I just dump it.
Thanks

Well it depends on what kind of heatsink you have, but there are little metal clasps that attach themselves to the sides of the socket, there should be a metal clip with a slot for a flathead screwdriver. You put the screwdriver tip into it, press down then outward away from the socket with it. Yes you need to separate the heat-sink from the processor to get it out of the system. This means you will need to replace the thermal pad either with another thermal pad or thermal grease for the second system. Some people can detach the metal clip with just the one screwdriver but I find I often need a second screwdriver to push the clip outwards while I push down with the other.

Good luck.

There are no metal clips such as I have on my own AMD system. The HSF is Intel and it has black plastic holders going down to the white socket underneath. There are ridges in the plastic, but no place to insert a scredriver. There is also a green plastic pressable thing at the top of the fan unit. I have no way to post a photo...sorry
Thanks

Before you go out and buy something, you did clear CMOS first, right?

I'm not very familiar with 370 stuff

Did you check the other side of the board? I know some heatsinks have parts that fit through holes in the motherboard and you have to get to the underside of the board to get them off.

Could you explain more about the green plastic thing?

I was under the impression that 370 stuff attached in pretty much the same way as socket A stuff with a metal retention clip. (my first system I built was socket A, but I've messed around with some older office rejected systems too trying to get them to work with some success). Is there a chance there's a metal clip in there holding it down and you just need to get past the plastic to get it off?

Does the black plastic go all the way around the socket underneath it so you can't slide it at all?
