Hi, so today my computer randomly shut off without any warning, it has been running fine past 2 months. I couldn't start the computer after this random shut down, so I decided to do some troubleshooting. I first thought that it was the PSU that got overwhelmed, but it seemed unlikely,(because it had run fine for a while) but i decided to try to disconnect the GPU fan from the PSU and then start the computer without removing the graphic card from the mobo(huge mistake), when i did that the computer started and all fans but the gpu started burning in one particular place(My other problem).

So now I don't know what to do, does my warranty apply to my GPU when I treated it like this? Is my PSU the root of the cause of this problem? Why did my computer randomly shut down, what is my next step? Is the graphic card disposable, or can it be repaired?(Picture link below)



System Specs


plexgear 500W PSU
ASUS GeForce GTX760 DC2OC 2GDDR5

if you need any other specs which I think is highly unlikely, just tell me to write it:>, i think those 2 are enough for the moment.

There is the picture to show where it got burned, its a small chip, i think it used to look like the chip below. I am wondering if this is fixable by anyway

I can't find any reference to a plexgear 500 watt PSU which makes me think it's cheap and not good quality. The Nvidia GTX760 requires a 500 watt PSU BUT cheap PSU's rarely give out what they advertise and it could have been working overtime for the 2 months to power your system.
It could of then started to fail causing the root problem. I would suggest trying a new PSU.
I would buy Antec, Seasonic, Corsair(not cx series).
If you are going to buy a cheap one I suggest buying one at least 600 watts.
As for the damaged graphics card I can't see from the picture how badly damaged it is:(
You could always try returning it and somehow forget that you unplugged the fan;)

Alritey then, thats what I presumed aswell. I'll buy a new PSU later but what I really wanna know if I should just throw away the graphic card or if I can fix it somehow.

Here is a better picture of the part where it was burned, its just that small part there that burned. https://www.dropbox.com/s/gh0ekqmgevf9fzp/20131130_131610.jpg?m=


Tell me if you need a better picture

It looks pretty well burned:(
I would try sending it back under warranty but that's your choice. I doubt it will be able to be repaired unless done by the manufacturer.
I know it doesn't help now but if you get another problem please come and ask on these forums before you try anything yourself. At least until you've got some more experience with computers.
We are always happy to help.

I asked around in a native-language forum, and they said that this PSU is really crap and it would not have happened if I had a better PSU. But atleast im happy it didnt burn everything.

The PSU is the most underestimated part of the computer. It's the only component which can destroy everything when it goes wrong.
I guess you should just count yourself lucky that the rest of the system is okay and buy a good PSU next time
