Today I installed an old game (anon1404) and after being in about 15 minutes in that game, the machine suddenly died and gave burning smell. It failed to start afterwards, no post, no sounds, no video out, nothing.
On my motherboard (Intel Z68DB) I could see burn mark on a small chip. Now I might get a new motherboard for this, but the main concern for me is - why at all did this burn happen and how to take precautions not let this happen again.
My machine is powered with 850W PSU and has one GTX590. It never had any problem playing latest high-profile games (like mass effect 3, civ 5 etc. with high-settings) continously for hours. But iam wondering if installing and playing this old game made it fry -(May be this old game was using the on-board graphics and not the Gtx and MB got overloaded - if something like that is possible).
But I am also thinking if this is more of a voltage/ power/electric problem. Power for this machine comes from online-inverter (pure sinewave) - so no chances of fluctuation there - but in case there is some, how can we make the machine 'turn off' (like an MCB auto-off switches) rather than have the motherboard or other components burn? I have a spike buster between the machine and the inverter - but it didnt help. And how reliable is PSU in terms of supplying a 'steady' noiseless output? (Mine is Corsair 850w PSU). If PSU is compromised, is there nothing that can help save the motherboards?? Some kind of fuse on MB??
My specific question is:
1. In your experience: what are the possible causes the motherboards (or any other component in general) can get burnt? And how to take preventive actions against such conditions?
After this incident, I am really afraid to start my machine, not knowing what would do damage to what.
(Just like most others out there, I had to save and put a lot of money to build this machine piece by piece slowly over months, and seeing its parts just go in smoke all of a sudden without knowing why, is really making me feel sad. I even purchased the online-inverter just to avoid these kind of power issues - but seems even it didnt help and now I dont know what else care I can take to protect it)
