Here are the specs for your HP Pavilion a1219h Desktop Computer. According to the specs, your computer is almost 7 years old. Please advise us if you clean out the "dust bunnies" inside your computer on a regular basis. If little to no cleaning and/or maintenance have been performed, your computer may be filled with dust that can easily cause the system to overheat and shutdown.

At the begining of theI did clean everything, I even replace the heatsynk compaund on the microprocessor, stays on a little longer but still shoots off'. I did try another power supply but nothing.

anyosua,

1) What is the case resting on? hardboard or carpet.

Did you clean out the front intake. You need to see pg2 and 4 of the service manual.http://h10032.www1.hp.com/ctg/Manual/c00311110.pdf

Unless you removed the front panel, you could not get to this area.

Everything that I try didn’t work, but finale I found  the problem: the 4 spring screws that hold the MCU heat sink unit are broken at the end, ( the plastic housing that holds the heat sink secure is broken) and I need a new one or a new heat sink assembly. Can some body let me know where can I find the exact replacement?
