Toshiba P100-St9612, How to blind flash please help!

Hi some one help please i have a toshiba p100 st9612 with a geforce go 7900gtx card. Two days ago my screen when blank. Yeah sucks, well i'm very good a computing but sadly i don't know every thing. Well my problem is i fallowed bart's boot cd guide (single boot cd). But i am not able to use bcd to create the image using the comman prompt so that i may be able to burn it to a cd probably i did something wrong. PLEASE HELP i'm out of options.

Sorry for late reply.
Well it's not the first it happened but it's the first it didn't come back after a force restart. I figured out the problem with making the boot cd, but now my problem if getting a good or workable 7900 gtx go rom. On a nother post i got a link(http://www.techpowerup.com/vgabios/i...ace=&memSize=0) to a rom but it turned out to be a 7950 gtx go rom. Tried a few but none worked any help would be oustanding. And my screen finally went will i was on the internet, it just flinched then went black i forced restart and got a blank screen. The back light comes on but can't see anything, it also boots but went it gets to the point were the screen flinkers after what should be the welcome screen the back light turns off and it oviously boots no further as i do not hear the log on sound i should here. please help here is my spec:

I have had it only about 2yrs 5 or 6 months. If u know were i could get the original bios for my card that would be outstanding, i really need to get my sys up again. Thanks for any and every help!

and here's a link to the other post and answers i got. Please help i paid $3100 and i don't think i have ot my moneys worth yet. And u would think it would give me trouble before i made a custom cooling pad for it dam it just did months of work for nothing.thanks for any help

Ok thanks for the reply. By the way would it be possible to buy a go 7950 gtx from toshiba and replace my 7900 gtx go. And finally if i got the orginal bios using the syntax nvflash -4 -5 -6 -A -y ronname.rom would it flash successfully or would i still get the slow single beep, then two fast beeps. Thanks again

Well i called toshiba center and the nearest repair depo and there weren't much help guess i have now choice but to buy a new card. Also i called toshiba spear parts and they said the 7900 gtx go replacement card would cost 700 dollars W T F o well guess i'll be putting 700 bucks in to toshiba leading lemon innovations pocket. Never buy a toshiba that's all i can say they even said they don't flash graphics card. TOSHIBA SUCKS!!!!!!!!!! if u get a link to my bios please let me know. Thanks

OK there are bad news and there are good news. Good news my graphics card is not totally dead and thus proves toshiba they shipped my notebook with a corrupt bios due to the fact that when i connect a vga monitor it shows and boots completely. Bad news my EEPROM is not support/ unknown so flashing my card with nvflash 5.72 is impossible. It would be outstanding if you could give me a list with both recommended and not recommended programmes i could use to flash my card before it is completely ruined. Reason being i am not able to play any games as there are a few artifacts. Please help as i spend quite alot o money making a custom cooling plateform for my p100 for propper cooling so any help would be outstanding. Thanks Again
