Opps, I think CPU have blown

Machine from my last post, Intel I3 oldy thing. Removed heatsink, so I could redo the compound, put it all back together, machine booted, reset, booted and then went off. I took the heatsink off again to resit it, but still not working, the machine turns on but that is it. Tested PSU, with tester, just in case. I hate intel way of sticking heat sinks on, never really had to deal with them, I presume that one of the pins was not set correctly.

Not sure what to do now, maybe try and get a cheap CPU from ebay, at the end of the day this is my mistake, so I will pay for it, maybe put a I5 in there instead.

i will leave it off for a couple of hours, a mate of mine said that sometimes they will boot back up after a while as if some sort of reset in them as it happened to him once. I can not see it, but you never know.

i do not make these mistakes very often, but this is what I get from mucking about with Intel.

Hi Adrian

The first question that sprung to my mine was

'What made you think you needed to redo the compound for the heatsink?'


I've caused myself no end of issue over the years trying to fix things that ain't broken so I now wait for them to fail first.

Are you sure it's not just a bent pin?

Is the heatsink on properly? Maybe the chip is reaching thermal shutdown and shutting off, you dont say if it switches off or can get into the BIOS.

The machine is getting on and the compound tends to not be efficient when it has been on the CPU for years.
Learn by my mistake., still my brother will get an even faster machine now.

Nah, i did not take the CPU out, just the pins, but I did take the CPU out a few mins ago, just to make sure that none of the compound have got underneath. Strange things these Intel chips, i only ever put installed two./

nothing on display now, so i can not get into the anything. I reset the bios, I even left the machine on for a few mins just in case.I should have realised something was wrong when the machine rebooted. Oh well I have ordered a I5 for £22 from ebay, i checked the memory was compatible and that is fine and the board will take an I5.

I was going to renew the compound on my own machine, but I think I will leave it alone

Good idea.

If it ain't broke don't fix it as the old saying goes.

I have long had a suspicion about the standard Intel heat sink mounting (assuming that is what you have). This applies pressure to the CPU that bends the motherboard, easily seen using a straight edge. The consequent stretching of internal tracks may strain buried via holes which are known to be fragile. So the problem could be a discontinuous track. Ideal planned obsolescence!

It is a good idea to use a heat sink mounting with a back plate that keeps the motherboard flat.
