Question about Compaq Presario 5000 PC Desktop
My computer was super dirty so I was cleaning the fan that cools the microprocessor. I couldn't get it clean so I removed the fan and the thing? behind it came off with it. I am assuming this is the microprocessor. I got it cleaned up and put everthing back together correctly making sure no pins got bend.
When I turned it back on, all the lights come on, both fans work, but nothing else happens. There is no beeping at all and none of the dvd players will open but the ligfhts are all on. Is there a procedure that you have to do if the microprocessor comes out? Please help if you can
If the pins were not damaged when you reseated the CPU before then it was inserted correctly but might not have been fully, just be gentle when you put it in and when you are confident that the pins are lined up, push in firmly and then lock it down with the lever.
Something very important, although you have left the old thermal grease on it will still work to absorb heat from the CPU to heat-sink, but when cpu and heat-sinks have been separated, you must replace the thermal grease because there is a high chance that air is trapped inside the thermal grease which will reduce cooling efficiency by a large amount.
If you ever apply thermal grease, do not put too much on, only i VERY thin layer enough to cover the top of the CPU.

Even though you said no pins were bent, my guess is that one of the pins either bent or broke off completely.
I am assuming that since you were inside cleaning, the computer is out of warranty.
Try examining the CPU (thingy under the fan) for any bent pins or broken pins. The alignment back into the mother board is crucial. Usually there is one corner with no pin or the corner is squared off to indicate the positioning of the chip in the pin holes.
Reseat the CPU and make sure it goes all the way down flush to the motherboard.
Usually there is a lever beside the CPU that you can lift that makes it easy to install or remove the CPU. It is called a Zero Insertion Force (ZIF) lever.
Personally, I'd recommend a professional or very knowledgeable and experienced friend help you reseat the CPU. Otherwise, you will need to replace it and they are not cheap.
However, if the CPU is damaged beyond repair, you might find a good USED one online at a decent price.
