Ok, about a week ago I started to try overclocking and I flashed my 7900GTX with the unlocked BIOS, I then used ATI tool to test different speeds and found one that works pretty well. It was only applied for maybe 12 hours. I never actually flashed my BIOS with the speed and the only way I could use the speed is if ATI tool was open. Since that one time I havent had time to mess with overclocking.

Yesterday afternoon I used PowerStrip on Vista to try to create a custom resolution for my TV but it never worked right so I stoped tryign after about 5 minutes.

Now for the problem. Just to help my explaination by computer is not set to go to sleep when I close the lid. It will just sit there. Last night when I opened the lid after it had been sitting there the LCD would not come on. It was black, BUT the lights that iluminate the screen were on. When I closed it the lights would go off and then when I opened it the lights would go back on. I did this about 4 times or so then the picture came back. I though nothing of it and I went about my night. Well tonight I opened the lid after it was sitting for a while the same thing happend. The problem is, I CANNOT get the picture to come back. I have restarted numerous times, I have even booted into XP (I an set up dual booting). I can not see the BIOS screen, I CANNOT SEE ANYTHING.

I tried to hook up an external monitor (my 40" LCD TV) and it worked. I could look around and everything seemed normal. I went to the display configuation and the ONLY option is for single display. It is like my computer LCD is not there at all. I then went to XP with my TV connected and the TV worked but my LCD still didnt. Once again I couldnt get my LCD to come on. I then went back to Vista and now my TV doesnt even work although I imagine I can get ti working again.

what do you think the problem is? I have complete care so should I call and just have it replace? It shocks me (like a static shock) anyways. If I do go that route because I cant fix it, will they know the GPU has been reflashed?

If I would want to reflash the GPU with the stock BIOS (If I can even find it), I will be doing it completly 100% blind as my TV will only work once the OS is up and running and not during the boot up. I need some serious help here. I have to go to bed because I have class tomorrow but any help will be much appriciated and I will respond ASAP.

My main questions are...

Possible fixes?

Do I need to flash the GPU with the stock bios if I am going to have Dell replace the laptop?

Thank you,

Ok,

In the last hour or so I have uninstalled my gpu drivers and I have installed dells drivers for the card. I was able to use my LCD TV (VGA) for this.

I have tried to put the stock bios back on. I was completely blind here so I dont know if it all went ok. I did it a few differnt times to try to make sure I got it right.

I have also reseated all of the LCD cables.

Any other ideas? Can dell really tell if you have tried to overclock? Thats the only thing I am worried about.

*EDIT* I just went into ATI Tool and I can still edit the speeds, so maybe I didnt get the original GPU BIOS afterall. I am using the JLMOD hacked bios and it says that I can use the 790GTXNN.ROM to put the original GPU BIOS back on. Thats the one I used but it appears that the BOIS is not locked. If thats the case, where can I get the orginal, stock, locked BIOS at. Or and I worrying to much because it doesnt matter?

As you can tell I am freaking out a little, my laptop seems screwed......

Most dell Techs don't even check to see if it was overclocked, and seeing as how overclocking your video card probably has nothing to do with the LCD going out, just give them a call and see what happens. Just don't mention that you overclocked your video card to them.

They should send you out a replacement LCD.

Yeah I tried that. Really I tried everything I could think of. I called Dell and they are going to send out a tech to replace the LCD. Meanwhile, I went to Best Buy and got a 19"LCD and once they install the replacement in my laptop I will return this 19" to best buy...

I called dell about 24 hours ago to tell them about this problem and a Dell tech just left. He replaced my LCD and the cables for the LCD. The new one works fine now with no problems at all. The LCD was my problem.
