I have made a LOT of threads about my issue but I dont get a clear answer. My motherboard is a gigabyte ga-880gm-d2h rev. 4.0 and it has gigabyte's hybrid efi. Many people with old pre-built pc's (just like mine) are complaining that the 750 ti is not working. And they say it's because of their bios being legacy (mostly hp users). All of them have windows 8 and above. I got my pc from an oem manufacturer and I have windows 7. I have seen many people in youtube "reviving" an old pc from like 2005 and installing a gtx 750 ti or even a 950 while the pc's motherboard was built even before uefi bios was invented. Maybe all this has to do with windows 8 and 10. Please give clear answers about my problem because I am not willing to spend 140$ for nothing...
