K8S-LA mobo heat sink fell off.

On my K8S-LA mobo the heat sink fell off of a chip right beside the CPU chip, sink and fan. Don't know what this chip is, but it overheated and shut down the CPU. I have stuck it back on, just using the remaining heat transferring glue, but it may not stay put. The sink has press-down handles on each side, but there is nothing on the board to latch it under; it seems to be held just by the glue.
What is this chip and how can I adhere the heat sink firmly?

That is the 'Northbridge' chip that provides the I/O interfacing for the main chip. The heat sink is normally held on with glue as you surmised, and should be re-done with a thermal conductive glue. The glue (a silver filled epoxy) is available from MCM electronics or from Mouser. Be sure to thoroughly clean the chip and heat sink before re-gluing.

    There are two small round wire hooks diagonally from the hooks on the heat sink. probably one or both of them have come loose and fallen off. I have a neighbor's computer I looked at that did the same thing. I tried powering the computer up and must have burnt the chip up doing it without the heat sink. if you look you might find one of the wire hooks on the mother board that is left or the holes where they were...

you need the right heat sink for the cpu that you are using for the board check on board for cpu plug in, then plug the fan in make sure that you have enought heatsink paste on cpu not to much just enought to do the job. if that dose not do it then the board is bad.

[Let's take a look at a Motherboard Diagram, that fits the technology of that Asus K8S-LA (Salmon) mobo,

CPU = Central Processing Unit. Another term used is Microprocessor, or simply - Processor - for short.

As you can see the Northbridge chip, of the motherboard chipset; handles the Faster capabilities of a computer.
Processor, Ram Memory, and HIGH-speed graphics.

HIGH-speed graphics is AGP, and PCI Express.
A graphics card inserted into a PCI slot; or using Integrated Graphics; is NOT high-speed graphics.

The Southbridge chip of the motherboard chipset, handles the Slower capabilities of a computer.

A) The PCI bus. (And Integrated Graphics)
B) IDE bus
C) SATA bus
D) USB bus
E) Ethernet bus
F) Audio (Sound)

The Northbridge chip of the motherboard chipset, is a SiS 760.
The Southbridge chip of the motherboard chipset, is a SiS 964.

Chip and Chipset are slang terms for I.C.
Integrated Circuit,

Driver: A small piece of software that allows the Operating System to communicate with a device

Device in question is the Southbridge chip.
Operating System is Win2K (?) ]

I have a Toshiba Satellite A215 and it keeps shutting down and getting hot. I don't think the internal fan is working. Can this be fixed and is it expensive?

Replacing the fan on the CPU or the GPU, Graphics card, is actually very simple and the fan will run about $20 to $25 depending on what type of fan you get and where. Aside from a new fan you will need a small tube of heat sink compound. The fan just clips on to the CPU. Make sure you get a fan that is designed for your CPU type or it will not fit properly. For instance, if you have a P-3 CPU you can't fit it with a P-2 Chip or P-4 chip, they won't mount correctly and subsequently they won't work. When you go to Best Buy or the computer shop your to buy your part tell them what type of CPU you have and that you want the cooling fan and the heat Sink Compound to mount it with. They will be able to direct you to the proper fan Type. Also, while you have it opened up take the opportunity to use canned Air to blow the dust out of the machine. If you are doing what is called Over Clocking it is important that you know you may have burned the CPU out as this causes the CPU to heat up more than it would if you just had it installed for the proper speed. The old fan will be difficult to remove because the old heat sink compound will have formed a bond between the fan heat sink and the CPU itself. If you have to do any prying to remove the old fan make sure you do so carefully and make sure you clean the old heat sink compound off the CPU before you try mounting the new fan. When you apply the new Heat sink compound you want to place the compound in the center of the CPU and let the heat sink spread the compound out in a thin layer. This compound needs to be spread evenly so it forms a good bond between the Heat sink and the CPU itself to properly transfer the heat from the CPU to the heat sink so the fan can properly cool the CPU.

The ASUS K8S-LA main board has a variety of chips on it, however only the CPU is large enough to justify a dedicated heat sink.

The most likely location that your rogue heat sink is came from is your video card's processor. I'm lead to believe this for 2 reasons- 1) you say that the CPU heat sink is still in place, and it is the only heat sink on the main board, and 2) the location you described as to where you found the heat sink would be consistant with it falling off the video card (located in the AGP slot, directly below the cpu with the external ports facing left).

Below is a link on the HP website to the layout / photos of your main board which were referenced in this solution
Click Here

This is actually very serious if it is the case as it could lead to rapid failure of your video card (or whatever card it goes to if that is the not the location). There are several guides available on the internet for "cleaning" heat sinks which will serve your purpose of reinstalling yours once you find the location.

Hope this information was helpful, please don't forget to rate my solution.

How to remove the cpu from mobo.

Was the heatsink screwed into the mobo or was it clipped to the plastic? If it was screwed on the processor is soldered to the mobo and cannot be removed. If its a ZIF socket then more than likely the lever has broken off and the socket is pretty useless now, time for a new mobo.
