EVERYTHING runs fine at first. then I took the retail HSF off to apply silver-stuff.

put it back and it never wake up.

took out the mobo bios, reset, replace RAM, yada..yada...yada....re-sit the CPU,...
and even w/ only mobo + cpu + video card ONLY.

NOTHING works.............

TOOK OUT the HSF and power on w/ my FINGER place directly on top of the CPU. NO HEAT and COLD as ever....

1. DEAD CPU? (but at least current should pass through so the cpu will get warm right?)
2. DEAD MOBO? (but, if it is dead will I still able to "power up"?)

I have tried rest of parts w/ my current AMD system and varified they works perfectly....hmm.......so what's my problem here? :(

EDIT:
The powersupply has absolutely no problem.
The CPU fan will works when "power on".

Something like this happened to me a while back... did you just by chance take the motherboard out of the case to apply the thermal compound? If you did, I can bet you that you put the power switch jumper on backwards. Flip the power switch jumper around and then see the result.

Although my mobo is complete dead, but I like to know more about the PS jumper issue, please.
(first time into P4 system)

Does it really matter? Can anyone confirm this?

How easy is it to kill a P4 cpu?

well lets see here. Pentium 4 has the ability to declock it self if it gets to hot so if the heatsink fell off (and u arent ovreclocking) it would be good still. (supposedly i believe). Basically only few ways i can think of killing a p4. Hammer, dropping it, breaking pins. So doubt what u did broke the processor.

Most likely its motherboard or something else............ I could be wrong tho )

But if nothing turns on (including fans) then make sure the switch on the back of your powersupply isnt switched off (if it has it). umm.. few other things but im to tired to think any harder :\

Well if nothing even including case fans, lights on harddrives and ecetera...then its the power supply...

If you are getting fans turning on but no post no boot then it may be cpu or mobo...cpu should give beep codes..

You've tested the ram right???

Damn I hat ewhen it left to the big 2...The one where you are less likely to extra parts of lying around you can test...

Do you have speaker in case installed??? Do you hear beep codes??? NO...then its the mobo...I haven't heard of a newer board taht doesn't implement this...

There is almost no way to actually kill a P4 via letting it get hot. You can in fact run a P4 without a HSF on it and it will go just fine....yes it will clock itself down a good bit, but it will still run.

That said, it sounds like one of the following has happened with your HSF switch:

1) When putting hte HSF down on the cpu you physically damaged the processor - not very likely at all

2) When putting the HSF down you damaged the mobo in some way - very possible...check for loose capacitors and/or scratches on the front and back

3) If you removed the CPU then put it back on, perhaps you bent a pin?

Sounds like something got damaged somewhere....but its hard to say if its your mobo or not. If you have a friend with a P4 mobo I'd take your processor over there and give it a go. If it works fine, then you know its your mobo, if it doesn't work fine then somehow you damaged your processor(perhaps a static discharge?)

How easy is it to kill a P4 cpu?

Its funny that you ask. I just put together a Socket 423 1.5 on a Via P4X266 mobo. The case doesn't have alot of venilation, and the CPU runs about 60c under "norma" usage. It has been extremely hot the last couple of days, and my computer room bears the brunt of the heat. It was about 98F in here, when I touch the side of the case. It burned me. I opened it up and everything I touched was too hot. The heatsink on the CPU was waaaayyyy hot. I shut it down and an hour later turned it back on to asses the damages. It booted like there was never an issue.

At the same time my 2.0A @ ~2.5 it running about 48c with no problems.

Make sure the caps on the motherboard is ok. Sounds it might be your motherboard. You migth have know a cap loose when installing the HSF.

Thanks fellows.......


I read from some articule that among the HSF pressure on top of the P4 is like hundreds lbs.?
I took out the mobo and examine carefully w/ the capacity and found NOTHING loosen.

HOWEVER, motherboard seems to be "BEND" at where the CPU sits on. (must be the pull or whatever you call which to secure the HSF)

oh...well...:(

BTW, which mobo would you rather have SiS645 or 845D????
