Windows 7: Desktop now almost dead after cleaning interior after thermal events

Desktop now almost dead after cleaning interior after thermal events

My computer used to shut down and a message used to be displayed that there was a thermal event. I opened the computer, remove the screws of the fan and cleaned the heat sink underneath it of dust which it had a lot( and of course other parts too). after that I put the fan back but I am not sure whether I put it in original upside down position or in wrong way, anyhow the wires connecting with the fan are now in between the fan and the heat sink but computer still continued to shut down suddenly off and on sometimes even before booting. I again opened the computer and this time even unscrewed the heat sink and cleaned it with air blow and a brush. After that computer has become like dead. When I turn it on a green light beneath the off on button lits but there is absolutely no sound which I used to hear when the computer used to boot. What should I do now? thanks

It sounds like you didn't put something back together properly. If you're not too keen about computer hardware, it is best left for the professionals because you can really screw something up if not put back together correctly. Usually CPU heat sinks have four notches that push down and lock into place. You will hear a click when that happens. Also, if you separated the heat sink from the CPU, you will need to reapply thermal paste to the bottom of the heat sink - Newegg.com - Arctic Silver 5 Thermal Compound - Thermal Compound / Grease


Can you take a picture of your motherboard and upload it here?

Also could be that you dislodged the processor from the socket.

I suggest you find someone who has done this kind of thing before and have the processor reseated and the heat sink refitted with new thermal paste.
If you are going to do it be sure to read the manual and be sure of what you are doing.

It reminds what we usually do. Before deciding to disassemble the heat sink, it was actually useful to observe first how the processor fan worked. Was it slower or even not running.
