1. I accidentaly touched my gpu with a metal object while the computer was running.
2. Immediatly when i touched it, the Led:s on the GPU turned off and my monitor stopped getting any signal from the computer.
3. I turned off my computer and everything started as normal EXCEPT the GPU and the monitor, it seemed like the GPU didn't get any power.
4. The GPU fans are running at 100%(i can hear it from the sound)
5. The VGA_Light on the motherboard is red all the time(shouldn't it just flash red at the startup?)
6. All the other lights on the motherboard are normal.
So i think that my GPU is broken and that the reason to it was a short circuit when i touched the GPU. Am i right??? And if i'm right, is it possible that there is like a fuse on the GPU that would've saved it from getting destroyed.
And if it was a short circuit can anything else be broken, all the fans are working and everything looks normal except the GPU. Everything insinde the computer looks normal except the GPU lights and the VGA_light (GPU lights are not on, VGA_Light is on all the time)
Here are some of the computer specs:
Motherboard: Asus p8p67 EVO
Video card: MSI Radeon HD r6970 Lightning
CPU: Intel i5 2500K
Power supply: Corsair CX750
So is my GPU broken?
Is something else and the GPU broken?
How can i fix any possible problems?
Is there any other possible way to try it?? I mean, what else could be broken since doesn't the lights on the motherboard show if everything is ok and in this case everything else seems to be fine other than the GPU. I just want to make sure before i buy a new one.
Did you already try a different pci slot? That way you can be sure that it is your card that broke and not that pci slot. That way you can know if you need to buy a new card or a new motherboard. IT sucks that you learned that hard way but now you know. Never open your case without turning off your computer and pressing the power button a bunch of times to clear out the remaining power because you never know what kind of lemons life is going to hand you. Also, be sure to always wear a static bracelet every time you go to touch anything in your computer. Clip it onto your computer to ground yourself.
You could have shorted anything to anything else by touching random parts of your card with a metal object. There probably are fuses on the card but they would likely be to protect against surges from the power supply, motherboard or some other predicable event- to protect against touching anything on the board would be a near impossibly task without fully encasing the components in resin.
Potentially you could have put over 20A through a chip rated for 50mA if you shorted the wrong parts and the damaged component(s) may not even be near where you touched it. Even if you tracked down all the damaged parts, they're surface mount components and some parts are ball grid arrays which mean all the solder points are underneath the chip itself and you can't readily solder them at home
What were you doing to short it out? Have you got another graphics card to test if you've taken any other parts of your computer out at the same time?

not in the traditional, pop down to radioshack for a 5A plug fuse but there will be some in-circuit protection either in the form of thyristors or as a small surface mount fuse not intended to be replaced by the user

I've never heard of anything being put on a card meant to fail to protect the card from even PSU surges, let alone from random pieces of metal being put on the card.
Secondly, lets say there was one, is the OP going to just go and learn how to unsolder surface mount stuff and solder on new ones?

If you can't do so then the fact that they exist is IRRELEVANT, that's my point, who gives a crap about something that can't be fixed, whether its broke or a fuse is broke it needs to be RMA'd.
As an aspiring engineer I agree. If something goes catastrophically wrong in a build I like to perform an "autopsy" to understand what went wrong, and why, so as to better understand how I can avoid making the same mistakes in future.

I've only heard of that working for ball grid array solder joints fractured due to thermal fatigue like on the xbox 360. To do this you also need to remove all plastic components from the board otherwise they'll melt in the process

Yeah baking is extremely unlikely to help in cases like thees. Unless the damage can be seen there is not really anything that can be done. Even if the damage can be located its only in rare cases repairs can be done. I have for example seen people solder jump cables to circumvent fired vrams (jumping power from adjacent mosfets) but with a random short like this it could be everything and anything that's fried.
That been said its not 100% sure the card is damaged. Depending on where the short was made (for instance shorting the PCI-E connector solders) it is possible that the PSU was damaged though that is unlikely as PSU's have pretty robust short circuit protection.
You really need to find out which is the culprit right now, the GPU or the MB before you start going forward and baking or soldering fuses and whatnot.
I know this sounds really stupid, but have you tried unplugging the cable connecting the GPU to the Monitor and then unplugging the monitor? I once had an Asus monitor that did this once in a while. Turning off the monitor and then unplugging it worked for some reason.
If you can get your hands on another GPU (doesn't matter how bad it is) and run it as your main GPU, you can then reflash the bios of the old card (may have been corrupted) as well as run diagnostics on it as well.
But find out which is causing the issues first. The Monitor, the GPU or the MB?

Yes, i could do this BUT my motherboard is a p67 and p67 does NOT support integrated gpu:s
