heatsink

[TKP]

i had a stock heatsink and i took it off and put on a Jet 7 heatsink. now my computer turns on but wont display anything on the screen. i have tried multiple monitors but none get any signal whatsoever. i tried removing video card and putting it back in and made sure all plugs were secure. i cant get the heatsink off now. right before i did this the computer worked perfectly fine. the only thing i touched to my knowlege is the heatsink and process for thermal paste. please help

if you can get the heatsink off check around the cpu that you
didn't crack the motherboard also smell for any odour coming
from the cpu

what processor do you have? if it's AMD, then you have to be careful when installing those huge HS. cracking the chip will damage your cpu. and check also if you have put some thermal paste between the heatsink and processor and also the levelness of the heatsink.

got heatsink off. put old one back on. still dont work. :_( i had thermal paste on and have an AMD processor. not sure what dax means by levelness. when i FINALLY got off jet 7 i looked at processor and it looked just fine. right around where the processor is looked a little banged up but was protected by plastic i think.

do you mean that little colored square (the die) is banged up??? if so, you pretty much killed your processor. and there is no plastic on the die.

plastic on the motherboard. when attempting to get off the processor the screwdriver slipped a few times but there is a little plastic strip on the motherboard to protect it. the part that is banged up is the ceramic part of the processor, but it is just a little srcatch no cracks or anything

levelness - the heatsink is sitting flat on the processor.

if the processor looks banged up, then you just damage the processor. and i agree, it's not plastic, it's the chip itself.

good luck.

please give us the details of your motherboard and processor so that we can see clearly what's happening. thanks

yeah the heatsink was sitting flat. no offense, but that last post was hard to read b/c it had such bad english. motherboard is asus nforce2 a7n8x (i think) NOT delux. processor is amd 2600+. (i hope that is what you meant by details.)

Remove the heatsink, clean off all thermal paste as good as you can, (removing the CPU will probably be necessary under good light). Look very closely at the core of the CPU...some call it the die. This is the heart of the processor, and it is jammed full of transistors. The "plastic" covering that you see, is very thin..and brittle as glass. Installing or removing a heatsink improperly will damage the core edges/corners...this instantly kills the CPU...sorry.

Check out the following page. It is of a dead Duron CPU...and was damaged by attempting to install a water block..same as installing a heatsink....wrong.

Right after the "A" type CPU came out...the successor to the K6-2 series with the metal cap protecting the core, I read where as many as 1 in 8 home builders were killing their CPU's by incorrectly installing (or removing) heatsinks.

Someone then invented a shim..to assist with heatsink install or removal without damaging the CPU..these were made from copper, and many people thought it was for heat transfer , but it was not.

I still use a shim..but today, you can get non conductive shims that take the load off of the core edges/corners while installing the heatsink.

that part of the processor is fine on mine. the part that is SLIGHTLY damaged is the edge of the ceramic thingy that is brown or green on most amds. i dont know what its called though, but its the part around what is damaged in those pics.
