Cant boot up my computer after cleaning my CPU.....

[LiTtLe_LiOn]

i just tried to clean my CPU[since its very dusty]
and after i install my CPU back to my motherboard
the problem comes up,
it can be switch on, but just for a few seconds, and it shut down itself
i think its something about overclocking
but i didnt even have time to enter bios setup......or reset its setting to default
can anyone tell me how to fix this?
thanks

you can try to reset your motherboard.. there should be some button or way to do that.. and by "cleaning" do you mean physically taking the CPU out of it's socket? did you re-apply thermal paste to the backside of the cpu?

as mentioned b4 did u apply new cooling/thermal paste ?

For that matter, is the heatsink and fan even seated firmly on the CPU again? Is the CPU in the correct orientation in the socket?

fan even seated firmly on the CPU again?

Really, check this, my computer did the same as your once after i moved it, and I just couldn't figure it out, after a while I saw the one of the things that holds the fan in place was looses, I pushed it in, and voila computer back to former glory.
