Hi,

I spent all the afternoon playing shadow of mordor, and at night, the computer just shuts down and when I press the power button, nothing happens... I've smell something like a component getting not (only after the computer hás stop, and i've turn everything off...

I have a Corsair 600W PSU , GTX 660ti, i7 3770k and the motherboard is a ASUS H88 I think...

Anyone got an idea of why it shut off? Its been 1h since it has stop...

Get up close to the PC. Maybe open the side panel. Smell around.

Does it have a very bitter / sour ting to the smell?

Like a chemical burn? Maybe melting medicine (just imagine it)?

Smelling smoke is not good of course.  I say test your psu using a multimeter and see if things are cool with it.  Check the motherboard to see if there are any blown capacitors and such.  ETC.

Too many ****ing games!  Back log 4 life! :S

Yes, on the back of the GPU i think, but i've removed it, and still nothing...

No blown capacitors on the motherboard, and both the GPU and the motherboard ligths from beeing powered are on...

Did you try to short the power on connectors? I know it most probably not work, but it is the simplest solution. If not, try and start your computer bare bone. One stick of ram, cpu

Short it? I did, nothing works.. Tried with one stick of RAM, motherboard and PSU only...

If the power goes on the board and goes to the cpu power management the only component that is stopping to turn on is cpu. There is a possibility of some dead ceramic capacitors, but it is slim as your psu would fail first. If you want to check the capacitors of your mobo you will need to find the datasheet for it and start from the power circuit, check the voltage and see if it is appropriate to datasheet. The other problem is finding a donor board... Basically, try swapping cpu and looking into the pins. If that does not help. I'm sorry you might have to take it to repair shop.

looks like you're gpu is dead? test the screen on the MB hdmi or dvi or displayport. take out your gpu first.

Thanks man, i dont have any spare partes to try that thought.. So iil have to take it to the shop... Just hope it isnt the processor, if it is the GPU or the PSU I can buy another, or a GTX 970... But the CPU... Best think I have in here...

If it is a malfunction in the board it will probably easy to fix for them as they have spare parts and datasheets available, but the reason we sometimes pay so much is troubleshooting if it is a common problem like the power chip isn't giving enough voltage so it just won't turn on then it is easy, but not all the time :( Just for this specific reason I have old laptop board laying around as donors, only had to use it once, but took a lot of time finding the problem. All the best to you and don't worry it's not your fault. It most probably has been manufacturer fault of chip.

The computer is almost 3 years old.. From time to time, the fans rotate once, and then powers off, but that happens like once in 20m..
