Help with Intel CPU

[jasontung]

Hi
My other computer is an Intel Pentium 4 CPU at 3ghz

When I tride to pull the fan, heatsink whatever its called out from the motherboard(i shouldnt have done it) the fan, heatsink came out with the cpu because of the thermal material there.

So i tried to put it back but when i do, my whole system failed. IS there a way that I can put the whole thing back in with out voiding the warranty?

Ive also contacted Intel Technical Support but I think theyll be a while because of the weekend

If I can get this fixed, I want to overclock the CPU and if I do, will WindowsXP want me to reactivate?

Please help
Thank you

How much force did you use to remove the heatsink and CPU from the motherboard? Did you rip off any of the pins from the CPU? Check the underside of the CPU for any missing pins or damage. If the CPU is damaged, it's dead.

Worse yet you may have damaged the CPU Socket on the board.
Just for your information there is very much on a computer that requires brute force to install or remove.

If you managed to pull the CPU when the fan and heatsink was still attached, that took a lot of force. The socket is a zero insertion force (ZIF) and is designed to go in easy, then lock down hard. Was the locking bar lifted? if so, the CPU chip will come out easily, and then the problem is getting it back into the socket without bent pins. I have gotten cpu's with a bent pin or three. It takes patience to solve, but it's not the end of the world, unless some pins got sheared off. But it takes a good magnifier, fine work tools, and a steady hand to get bent pins back in line. I have had to do about 4 CPUs that way, and haven't lost one yet.

Thanks for the replies
No, I didnt break any pins
Locking bar was not lifted
I realigned 2 bent pins but it still didnt work

[jasontung]

Also, I forgot to say that I did not use too much force to remove it. I just tried to remove the heatsink and fan but the cpu just came right out

[melloman]

It sounds like your chip retention on your socket is out. If the locking bar was not lifted, and it just fell out, the thing was probably not all the connected in the first place.

I would try to find another board to check the chip in. If you have a computer shop to try the chip in one of their boards, and possibly another chip in your motherboard, you should be able to find the culprit. I don't think your chip is making all the right connections on the board.

What kind of board is it? Is this an 800 mhz bus P4?

[jasontung]

The computer had worked before
The main problem now is the CPU is attached to the heatsink because of the thermal stuff

[melloman]

You should be able to get the heatsink off with a little prying, but the biggest problem there is you DON'T want the CPU to go flying (see: bent pins).

So, right now, you can put the CPU in the motherboard, and lock it into place? Or will the CPU retention mechanism for the ZIF socket not holding it in place at all?

[jasontung]

The socket works fine but the CPU is stuck to the heatsink by the thermal material, if I try pull the CPU off the heatsink, will it void the warranty

[melloman]

I have built loads of machines with Intel processors, and any Intel processors I have used didn't come with adhesive to attach the heatsink. Whatever that got attached with didn't come with an Intel package. It should not break the Intel warranty.

What kind of PC did you get?

[jasontung]

I got it custom made

But the person I bought the pieces from put the CPU and fan on for me because I bought it in Taiwan and had to take it back to NZ.

I saw him place the CPU in the socket and stuff but I dont recall him put any material on top of the CPU

I did the same thing recently. I pulled the HSF gently up and the chip came with it. It bent one pin. It is in a new build and working fine.
The Chip should be easily removed from the Heatsink. I wouldn't think that removing the chip would void your warranty.

The problem is, I cant seperate the HeatsinkFAN from the CPU, its got some stuff which I think is the thermal material attached

[not important]

Use a kitchen knife and slide it between the CPU and Heatsink. That should seperate them.

[jasontung]

OK, Ill do it now
And then Ill see if it works
Thank you

[jasontung]

Hi
I tried to use the knife and get them seperated, the knife blade is too thick here.
I cant manage to get find a gap to remove it

[Cricket]

Try a razor blade.

[jasontung]

OK
I tried, but it still not budge :(

I think that material there was on the base of the heatsink when it was put on

[morriswindgate]

Normal thermal compounds will dry out and make it fill like the CPU and HSF are glued together, but this sounds like the builder used Thermal Epoxy on it.

[jasontung]

so what is the difference between thermal compound and thermal eproxy?
is there any way to remove it or do i have to contact intel support?

[Cricket]

Thermal epoxy? It's basically epoxy with metallic particles in it to help transfer heat from the CPU to the heatsink.

If thermal epoxy was used, you might be able to get the heatsink and CPU to separate by heating up the heatsink with a blowdryer set to high and really warm up the heatsink. Then use the razor blade and try to work it in between the heatsink and CPU cap while everything is still hot. It may work...it may not.

[jasontung]

OK, Thanks I might just try that.
By the way, does the thermal eproxy "melt" at around 40 degress celcius?

Thats the highest tempreture I remeber seeing while using computer for the whole day

[jasontung]

In doing that I have a few questions:

1. I cant move it by pulling it up with razor blade so should I slide it off the heatsink instead?

2. Will doing this stuff up my CPU?

Thanks

[jasontung]

OK, Now I have some other problems

It boots up but then shut down after some 5 seconds

What may be the problem?

Thank You
Jason

[melloman]

Simplify the situation:
Remove all cards save the video
remove IDE drive cables from the mobo and the floppy cable as well
just try to boot with keyboard and mouse only, no other connections.

If it boots, then add things one or two at a time, and boot up, and if it's a peripheral that's doing it, you'll find out. If it's the mobo, then you have nothing else to rule out, it will act just the same.
Have you tried resetting the BIOS ?

[jasontung]

OK Thank you all
Now i have the problem solved, I dont know why it was randomly shutting down and all but now its fine.

Thank you all for helping me during the last 24 hrs

Glad to help....
