If the CPU heatsink (HSF) is loose, your computer should shut down to stop heat damage, this damage can happen very quickly.
If you try to boot up, it may power up for between a few seconds to a few minutes.
DO NOT try to power up if the heatsink is not fitted correctly, if you are unsure about other things plugged in correctly, you will need either a knowledgable friend to help, or a local shop.
It is impossible to give advice on what may be wrong without actually being in front of your pc to see what may be plugged in incorrectly

On one edge of the mother board, usually near to a corner, there's a whole load of tiny connectors, some single pin, some 2 pins. It looks like you've disconnected these.

There's no easy way, you'll have to check the user manual for the motheboard to see how these connections should be made.

If you don't have a manual, you'll have to go to the motherboard website, follow links for support and downloads for a PDF copy.

You're motherboard make and model will be printed on it somewhere, its a case of digging around.

INSIDE A COMPUTER OR THE HEAT SINK FOR YOUR COMPAQ COMPUTER?

The "CPU" or central processing unit, otherwise known simply as "the processor," is the primary "brain" of the computer. Processors are very finely engineered components that are not repairable. But replacing a failed processor is an option for the owner of any model Compaq Presario desktop computer. Just check with HP/Compaq for the correct and speed of processor for your motherboard before purchasing a replacement.

Turn off the computer and disconnect all cables. WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Remove the cover. Lay the computer down flat. If there is a plastic hood covering an exhaust fan, remove it by pressing in on the indicated release tabs. Examine the processor assembly. The processor is a square chip that is covered by a metal heat sink with fins. A fan will often be mounted on top of the heat sink; unplug its connection to the motherboard. Two clips usually secure the heat sink assembly to the top of the processor. Gently press down and slightly away on the flat end of a clip to release it. Avoid using a screwdriver to release a clip; a slip could scratch the motherboard. Release the clips and gently remove the assembly. The heat sink should separate, leaving the processor behind in the chip holder. Clean the bottom of the heat sink. Use a paper towel and a dab of solvent cleaner to remove the old thermal paste. Set the clean heat sink aside. Lift up the lever to unlock the old processor and remove it from the pin mount. Insert the new processor chip. Align the pins on the processor to the "cut off corner" or dot on the pin mount. The processor should drop into the pin holes easily. If the processor won't drop in easily, check the pin alignment. Once the processor is inserted correctly, pull down the lever to lock in the chip. Apply thermal paste to the bottom of the heat sink. Apply enough paste to cover the area of the small gray rectangle on top of the processor. Apply the paste with a spreader made from a piece of flexible plastic. Spread the paste evenly to a thickness of two sheets of paper. Check the heat sink mounting alignment and lower the heat sink onto the top of the processor. Reinstall the mounting clips. Reattach the heat sink fan to the motherboard if necessary. Plug in the computer and monitor and boot. If the machine won't boot or it emits warning "beeps," unplug the power and monitor, and troubleshoot your work until the computer boots successfully. Shut down again and replace the exhaust fan hood. Close up the computer and reboot. Hope this helps.

X box game wont come on. red light flashing


if all four lights are red your av cable or hdmi is loose. if its 3 red lights this is the red ring of death (RROD) and it needs repair. microsoft has a 3year warrenty for this problem. what happens is the console gets hot and the "x" clamps holding the heat syncs to the chips bends the motherboard and causes the CPU or GPU to come loose enough to where they aren't making proper contact with the board. I've fixed several of these including 2 of my own. what you do is take it apart, remove the clamps and the heat syncs. clean the chips. apply new thernal paste and replace the problem causing clamps with screws and washers. plug in the xbox with out the fan hooked up for about 3-5 minutes until you see 2 red lights flashing which indicated the console is ovrheating, let it overheat for 2 minutes unplug it and tighten the screws. the overheating of the console softens the solder on the chips and allows you to tighten the back into place.

This is the video I watched to learn the process. Its part 1 of 9 i think">

When i start up the xbox it has no video, only sound.


Its possible for you to fix the problem your self.
how ever the fix may not last long .

Ok hear we go

find a video on how to strip the box down to the P.C. board.
pull the board out of the chaise by the small heat sink only
do not disturb the big heat sink at all or you will break the
seal an get 2 reds ( over heating)

Now that you have the main board in your hand
flip it over a carefully very carefully pry off the x clamp
bracket holding down the small heat sink for the G.P.U.

remove the heat sink from the board ,take out the four
studs under the heat sink . clean the gray heat sink off
the top of the two chips with rubbing alcahole ,do the
same with the heat sink then apply some heat sink compound
to the chips place the heat sink back on the chip
get four 10-32 by 3/8 long and EVENLY screw down
the heat sink Not too tightly ( snug not tight) .

Put the unit back together ,leave out the white fan
shroud plug everything back in and leave the fan
hanging out .

Now plug in the power and a/v cable place and hold
the fan over the Large heat sink for C.P.U. and turn on
the power .I should take 4-5 min till the fan gets up
to full then another 3-5 min to over heat Two red light
be ready to unplug the second this happens .
let it cool down for about 15-20 min and you should
have restored your video feed. I cant say how
long it will last .

if you have any questions feel free to email me

Rob

Take some heat sink compound
that you can buy from raido shack




now that that you have the main P.C. board in your hand.

Intel DG965RY CPU Overheating


Check the clamp of the cooling fan. If the clamp is not engaged, heat sink didn't take the heat away from the micro processor causing CPU over heating.

How do you remove the heat sink from the CPU?


This depends on the CPU and the heat sink. The heat sink is fastened to the socket on the motherboard on two sides. It will be fastened to a tab on each side. In all likelyhood, the heat sink will have some sort of handle on it. AMD processors these days have a little lever that must be moved from the far right position up to the center. This loosens the heat sink and you can reach down to unhook first the side with the lever from the socket and then the back side. Intel processors seem to have a flat metal piece that must be pushed down to relieve tension on the clamp. As you do so, you have to get down by the socket on the motherboard and push the metal clamp away from the socket. This takes some doing, as it's quite tight. Once you have released the one side, the second side is loose and can be unfastened.
The heat sink can now be pulled up (use a slight twisting motion if possible to break the seal between the heat sink and the CPU. If the computer is several years old, the seal will be hard to break.
