Usually, the flash process will ask you to reboot after or will automatically reboot. Did you get this? Did your PC restart after the flash?

You could try to disconnect power from the computer and all cables behind. Hold the power button for a few seconds. Then replug everything.

In case it's a dead port you could try with a different port (DVI instead of HDMI or vice-versa).

If it still doesn't work your card is probably dead. Contact your GPU manufacturer to arrange RMA.

First, try everything I suggested in my post. Especially disconnecting power from the PC.

Then I would try to RMA it, yes they will replace it. Or if you have doubts just don't mention you were flashing it and say it died all of a sudden. But even so I'm pretty sure they will replace it last time I checked the new firmware is provided by the manufacturer so if something goes wrong during the process they should replace it.

Don't laugh at him. Flashing BIOS and firmware is usually a safe process. Most components don't have dual bios so it's not a reason not to flash otherwise you would never flash something. As I said it's usually pretty safe and works 99,9% of the time. I must have flashed thousands of BIOS and firmwares in my life and only once it happened to me to brick something. Shit happens sometimes but it's not his fault.

Well, the instructions on this website are very clear and well explained step by step. I don't know how differently I would try to explain it but using the same words. And they're also very long I cannot repeat everything there it would take forever... And I don't know why you say the BIOS is on the C:\, it doesn't matter you could simply download it again from another computer, or maybe find an older or original BIOS on the web if you want to reset it to default. You could also remove GPU and boot with integrated graphics if you want to access C:\.

Not sure about this. Maybe if you can get display from the integrated card while the GPU is connected at the same time, but I'm not sure how to do this.

By the way the link you sent me is for EVGA cards BIOS. Didn't you say in your original post you had a Gigabyte???

Even when I change to Gigabyte, there is no new BIOS version available there for the 780??? They're all version 1 (original version). For instance, if you have the reference card, you cannot push the BIOS of a Gigabyte WindForce OC since they have different fan profiles, it will not work or will cause major problems.

What BIOS version did you try to push exactly??? No offense, but now I think BigMack70 can really laugh at you. As I said flashing BIOS is usually safe but you need to know what you're doing first and be 100% sure you're pushing a compatible BIOS otherwise it's very dangerous.

Anyways, if all you wanted to do is a slight overclock why didn't you do it manually? It would have been a lot safer and simpler.

In any case, I read more about the guy procedure and you just need to go to the last part at the bottom of the page called "Simple Blind Flash Method". It's called blind flash because you can't see what's going on the screen during the procedure. Or he also mentioned it's possible to get a display from a PCI video card at the same time there's a PCI-Express card plugged in (so I guess it doesn't work with integrated graphics).

Good luck.

Yes I know this is your card. But as I said there IS NO new BIOS available for it! So what BIOS did you try to flash it with exactly???




I already told you integrated graphics WILL NOT work. Go read my reply carefully I explained to you what to do, it seems you don't understand English very well... The guy explained on his site that only a PCI card will work. Or you can use the "blind flash method" as described on his site.

I brought the computer to the store to me when I rode and have already managed to start the pc with intel hd 4000. I flash bios gtx 780 oc reference after the change to allow fixed values ​​993mhz and 1053mhz and turned to flash since then he has not already started.

But as I already explained to you, you CANNOT push a different BIOS to your card, it's very dangerous and that's the reason why it's not working anymore. You can only get the BIOS from Gigabyte when they will release a new one, and need to make sure you push the right one for your card (Gigabyte has 3 different models, you need to use the right one).

From what you did, it seems you don't understand what a BIOS is, what it does and how it works. Don't play with things you don't understand.

If you simply wanted faster speed, why didn't you simply overclock??? It would have been a lot simpler and safer.

Yes it does, lol. It's just that at first I thought we were dealing with someone more tech savvy this is why I took his defense. Sometimes even when you use the right BIOS shit can happen (although it's very rare, BIOS flash work in 99,9% of the case if you use the right one and the right procedure). But by trying to push the BIOS from a different card, yeah he totally "bricked" a 600$ card. I don't know if I should laugh or facepalm now...
