hey man can you please tell me wich one should i buy? but please make sure its not too expensiveThese https://au.pcpartpicker.com/products/motherboard/?compatible_with=intel-cpu-bx80637i73770k
From the main brands i said earlier you'll have no problem.
but before that i was wondering if my gpu dint work/broken. but when i start the pc it show "american megantrends" logo and my brother said that if that logo pop up it mean none of my hardware are brokenThat's up to you. Sorry I wouldn't know what's available to you second hand or how much. All i can give advice on is buy a board compatible with your cpu that is made by Asus, Asrock, Gigabyte or Msi.
But you said you see "american megantrends" logo which is during post, what do you mean there is no rig show up?yes i can. But when i turn on my pc there is no rig show up, never show up
i plug the 6 pin. Anyway i know why my screen went blank and show american megatrends for only a while, it because of my motherboard, i think my 750TI is not compatible with my motherboard and i checked gpu stuff in bios and there is nothing helpful and there is no option for external gpu... And btw i went to my cousin house just to check to my gpu is it dead or not and its not dead at all it can boot to windows10 right away, so iam sure i need to buy another motherboardWhich 750Ti model do you have?
Most 750Ti's don't need an auxiliary 6 pin to power it, im wondering if yours could have and missed it?
