A few days ago while I was playing a game, I sense a smell of burnt plastic coming from my computer. I immidiately turn off the computer to check what what happened. I thought it might have been some burnt dust as I had some dust build up so I cleaned it thoroughly. After I booted my computer again, it ran fine for about 20-30 mins and upon entering in-game again I smelled something burnt again. After looking in my case, I saw a capacitor lying around in it. After the third time I booted my computer, it ran fine for a minute or two and then it lost all display output and pheripheral connection and acting as if it failed to POST. After that it would always fail to POST, no display output and keyboard and mouse wouldn't light up. I figured it might have been the psu so I swapped it with a new one and had the same results. Interesting thing is that after swapping my psu and giving my computer a couple of power-ups, I tried plugging my chassis as well and after that the computer wouldn't even power up anymore. I'm sensing this might be the motherboard that's at fault here. (ive had no motherboard beeps) . I'm quite new when it comes to this so any suggestions what the culprit might be?
