While ago, i was cleaning my heatsink fan, wiped off the dust and cleaned the cpu. Now my pc wont turn on and if, it shuts down immediately and i noticed that ita temperature increased than its usual. Is it because i am missing something? I did not put anything else on the cpu and heatsink fan before i placed it in its place. Pls help, i am new to this. Thank so much!!!

Did you replace the thermal compound between the CPU and heatsink? Then, did you properly remount the heatsink so that it is firmly attached to the CPU?
Yes i mounted it back correctly in its place. And no, i didnt put any thermal compound between in it

So while ago, i posted a question here on why does my pc stopped working. First, i cleaned my heatsink fan and cpu. I forgot to put a thermal paste/compound and ran the computer. I first noticed before it shut down was the temperature is higher than its usual. Now, i read somewhere here that not puttin thermal compound may permanently damage my cpu. My pc wont start to run since after it shut down itself and the display is not detected anymore in the monitor. How can i fix this? Can i still revive it ? Im new to this, pls help

You'll never know until you try. Your CPU is probably OK. When it gets too hot it shuts down to prevent damage. How long was it running before it shut down? Make sure you properly clean both the heatsink and CPU before applying the thermal compound to the CPU. There are hundreds of online videos that will show you how to do the whole process.

It ran for about 2-5 mins before i noticed the higher temperature than usual and before it shut down on its own. Sure i will clean it again thoroughly, and should the thermal compound make my pc run again? I placed an order on my nearest shop so probably it will take a day or two to apply a compound on my cpu. But minutes ago i tried to open it to check if its gonna turn on, but no luck so i will wait for the thermal compound to arrive before opening it again
