My friend was having problem with his PC.His PC wont turn on but motherboard LED was on when he press power key PC turn on for a second then just turn off.I swapped my old Power Supply on his PC his PC booted up but for some seconds then turned off.Then we used his Power Supply on my PC same thing happened my PC wont turn on.I used mine on my PC same thing happened my PC wont turn on just like his.I used my Power Supply on his PC his PC turned on but it wont display.He brought another 250W Power Supply from his friend used on his PC same thing happened his PC booted but wont display i used his friend Power Supply on my PC still nothing happened.Then i decided to use old Power Supply on my PC.I turned on PC then i saw steam coming out of Processor fan i quickly turned off.Removed processor and saw it was thermal paste.Thermal paste melted on processor and some of it also dropped on processor chip.Is processor is safe?and really wanna know why PC wont turn on.


Sorry for my bad English.

I'm really having a guess that it was a bad PSU because the thermal paste can't melt out of nowhere. And since I'm guessing that your thermal paste has reached the CPU chip, you are in real danger since some of the processing information from a CPU core, I'm guessing that your thermal paste has damaged a core, and a damaged core is real bad. So your going to have to buy a new CPU unless if the core is strong enough to withstand melted thermal paste.
