Yesterday I took out the cpu and the cpu fan to reapply a new layer of thermal paste. Today after I put it together again, it has refused to boot up and on the sceen there was only the no video input sign. I tried taking out the ram but I did not hear any beeping sound. Could it be the motherboard's fault? I was really careful when I put it together.

All i know is i liked it better when cpus had pins, the other stile when its the socket that has the pins they can get bent and if that happens its not a lot of fun.

Cool the AMD cpu is pins on the chip, well my self i would reseat the cpu and play with the lock down arm, like lock/unlock x5 with some electronic contact cleaner "zippo fuel works too" and see what happens, might be some dirt in the hole or something.

This could be the result of too much thermal compound, especially if you used a compound like Actic Silver which has a small amount of metal in the compound which could result in shorting the CPU.  The amount of thermal compound should about the size of a grain of rice.

 

I would go back and check all of your connections, even disconnect and reconnect connections to make sure they are secure.  I would also remove and reseat any components or boards which plug into the motherboard.

 

With the thermal compound being fresh you shouldn't need anything other than a facial tissue or a soft cloth to clean both surfaces of the heatspreader on the CPU and the heatsink.  If you do need something to finish cleaning the surfaces I would suggest rubbing alcohol.  I definitely would not use any petroleum by product to clean these surfaces as they will leave a residue.
