So. . . I dun goofed and could use some help

[superdum2]

I made the mistake that I often do, and decided to not sign up for a forum site that is devoted to what ever it is I am beginning to learn. so after jumped in headfirst and mining dogecoin for the fun of mining I edited a batch file I originally created following the tutorial here (http://leak.sx/showthread.php?tid=199339&pid=3005968#pid3005968).  

I was mining fine for the first 2 days while I was out of town with zero hardware errors while running on a low 80 kh/s I then began to research some more and decided to increase the intensity to  bringing the rate to about 300 average.

then I read somewhere that by changing it a bit would yield better results.  So without thinking I copied and pasted some text and then a million problems occurred.

my minewithamdgpu batch file now contains this

Code:

cgminer.exe --scrypt -o stratum+tcp://doge.scryptpools.com:3333 -u username.password -p password --thread-concurrency 4096 -I 10 -g 1 -w 256                                                                                         

I then ran the file and my gpu started speeding up and I began to hear a buzzing sound for short seconds going off and on.  Then my monitors shut off, and so I tried turning it off but the power button no longer seemed to work after holding it down for 5 seconds, so I shut off the power to the psu.  after doing this I tried rebooting, it turned on but there was no picture.  I then reset the cmos, removed all components but one stick of ram, and switched to on board video.  now the pc does not turn on when I hit the power button can someone explain what originally went wrong with the code other than I was a dumbass, and how I can restore my pc to its previous state if more information is needed like what motherboard I am using please let me know.

The GPU is the Sapphire Radeon HD 7870 GHz edition.
  Any help would be appreciated.  

EDIT the code I posted was the exact same as the tutorial I posted, I may have opened and edited the wrong batch file and ran it I will check tonight when I get home from work.  In the meantime anything anyone thinks may help please do not hold back.

For a 7870 I know that the thread conurrency should be twice as that e.g. 8192, with an intensity at small as 10 there shouldn't have been any problems. A lot of the times, leaving the computer off completely for a while then re building it can help. That's usually a last resort if most conventional methods fail. Then if that fails, then I try and replace the faulty part if I find one. If you have any other problems just RMA the card.

Thanks I will try that tonight.

Looks like you fried your graphics card.

Don't worry though you're not alone, look here:

https://bitcointalk.org/index.php?topic=101624.220

Every page there shows at least 10+ people who have fried their graphics card as well. Mining is a risky business, if you don't go in prepared, be prepared to lose.

You should be cautious when trying out people's settings, you should always make sure that they have the same graphics card type as you do and that theirs isn't overclocked or watercooled or some other modification.

I look here for all the hardware settings I set my GPU to:
