Hi all, You helped me in the previous topics so I hope this time you can help me too. I have problem with Gigabyte GTX 960. Тhe card has power for gpu , power for memory and other ones (3,3 , 5). I checked shorts but not present. When I received card I replace two 0ohm resistors to bios chips. They were broken. Now when I try to turn on PC I can see 2b code on the POST card and it freeze. The power is still present. I think that it have to be something with bioses, however I reflashed them and it didn't help. What could broke those 0ohm resistors? What should I check? ThePCB looks like this: https://img.hexus.net/v2/graphics_cards ... 0WF-2b.pnghttps://www.vortez.net/contentteller.ph ... e&id=29336Here is the place where are 0ohm https://www.modders-inc.com/wp-content/ ... g1bios.jpgLast question, which component is responsible for switching bioses? Is this one marked as U20?

Hi, again. aleksros писал(а): aleksros , I didn't see your picture that is why I don't check it like you wish. Now I Checked it there are 3,3V everywhere. I have ran this card on my second PC where I have graphics on my motherboard. What is more the "Device Manager" see this card. Unfortunately, there is an error 43 . Sprawdziłem także tę kartę za pomocą GPU-Z i jest wersja BIOS-u - niezdefiniowana i pamięć wynosi 0 GB. Załączam ekran drukowania GPU-z. I tired to use nvflash to update bios but I have errors.

BrasilBack писал(а): I Resistances look ok. This card has dual bios. I have CH341A programmer. I have downloaded bios from this site: https://www.techpowerup.com/vgabios/178 ... 096-150701 and write it to both chips. I havent got oryginal bios unfortunately. Is this procedure ok or I have to do something else? Maybe have you got another bioses for 4GB card? Posted after 3 hours 53 minutes 30 seconds:Hi again, I don't know how but I made a mistake. There are missing 3,3V on the 6th leg of bios chip. It is SCLK (serial clock input). I have tried to add 3.3v from external source and the PC starts but without screen. Can it be a GPU faulty? Posted after 1 hour 12 minutes 25 seconds:Update: I took off GPU, and the power is back. However I'm still not sure is it GPU faulty. Is someone can confirm?
