Something happened to my pc after took it open for cleaning. I did some dusting with dry cloth, and removed the cpu air cooler to blown away the dirts stuck between its fins. When i put everything back and powering on, the pc will either:
a) its cooler, PSU and system fans will run 1-2 seconds before immediately power off automatically. No error beeps at all.
b) the pc is powering up (PSU and system fans will run continuously), but no POST at all, neither the error beeps.
So far, i tested with another PSU and motherboard but the problem remains. I tried to take everything out and put together again and still no luck.
What else could be the problem? Is it possible the processor gone kaput (i only detached the CPU cooler for cleaning) or i didn't properly re-applied the cooling paste on CPU and so the system prevented the powering up?
