Intel DG41RQ - 4 beeps and shutdowns itself, help?

Hello guys, I have a weird problem and I'd like to know how to fix it, suddenly one day, my computer did turn off itself, when I tried to turn it on again, the Motherboard, an Intel DG41RQ gave 4 beeps, then it turned off itself, I already tried removing ram memories each at a time, and still the same, I cleaned the whole computer part by part including thermal paste change, same thing, I was able once to turn it on a few more seconds, and the screen displayed this message:

The following are warnings that were detected during this boot:

Warning: Processor Thermal Trip

The message says something about the processor temperature, am I right? could you please help me out? thank you, I appreciate your help!
