Ah ok but the usb flash drive i'd already tested and doesn't seems to work, the activity led on the drive doesnt flash
does the keyboard althoungt work when the numpad led doesnt light up ?

numpad indicates the bios is loading so i guess thats a no...unplug the hd and have an autoexec with the command "nvflash -4 -5 -6 --auto -y [romname].rom" and leave it a few hours or whatnot...make sure the new rom you are flashing to is compatible/stable with your gpu

Edit: sorry to take so long to respond...must seem like an eternity without your gpu working

Just wanted to thank you, I got the blank screen of death from flashing the 1.24volt version of Juan's new bios for the rev 1 7900gs. It appears that either the file was mislabled or accidentally copied from rev 0. No amount of cd flashing, neither reflashing Juan's or the one from your FAQ helped, but the thumbdrive flash did the trick. Took about 10 seconds and I was up and running again! Used the original bios posted on the thread from Juan's. Reps to you.!

Just here to help...made a few changes to the guide and havent really read over it...any suggestions will be appreciated

Same problem... NUMlock won't flash at all. I removed the HDD and put a bootable USB key AND a bootable CD for the night.... I'll see tomorrow morning if it worked during the night. (Is it possible for NUMlock key to finally light up like 1 hour after the computer is turned on?)

If I can't get it to flash, I assume it's a "back to DELL shipment"

Yes i mentioned that in my first post I think....Numlock can take over an hour to light up....just put the usb in and forget about the cd...I think im gonna remove that part from the guide...the cd works for me but other ppl report it not working and usb is just easier anyway...

Hmm I'd left the flash stick overnight on the book but the NUMlock doesn't light up and nothing worked again

Same situation here... hehe Looks like I'm gonna have to take a look for a new card on eBay

Can't get the system BIOS to load at all... the screen doesn't even light up! scary

Phazon try it again with only the flash drive (its worth a shot)...it could be that the cd booted first and did not work...I have not personally heard of a case of the flash drive not working yet...make sure you use -4 -5 -6 as well as --auto -y....The first part is crucial

Edit: I'm about to just remove the bootable cd from the guide

Hi zzpulp, as I said, the system BIOS doesn't seem to load at all... No NUMlock key. The backlight doesn't even ligtht up which is scary...

I discovered that the BIOS I used was unreadable (bad CD-RW). If only I had another video card to test it. Hope the motherboard isn't dead.

I gave it a try with the flash drive last night (wiht -4 -5 -6 original.rom --auto -y), with no luck.

I'll try something else... like calling DELL and send back the system for repair

hmm yeah, ive never experienced your problems....good luck

Little update of the situation:

I found on Dell.ca (Canada) that you can run a diagnostic test by holding the "FN" key and pressing the "Power" button...

The code I get: = Video Card Error

Conclusion: The GeForce is toasted (physically?) Anyway, it won't let my system boot... hehe

I doubt its physically fried from a BIOS flash. I would look deeper into the blind flashing, maybe redo it, perhaps you mis-typed something.

The system BIOS doesn't load at all :P I really don't know how I could blind flash the video card if I can't even boot on a CD-Rom or Flash memory stick hehe

Mega-kudos to zzpulp for this info. I used the hpflash1.exe to create a bootable disk on my USB thumbdrive. I used IsoBuster utility to open and extract files from the various BIOS flash progs and put them on the thumbdrive. Rebooted onto the thumbdrive (LOVE that good old Win98 screen!) flashed my nVidia BIOS, and rebooted to my OS. Smooooth as the proverbial baby's bottom Thanks much.
