Hi, so recently I have bought some new parts for my pc, and have used the same gpu, psu and hard drives from a working pc. The new parts I have bought and added are a motherboard, ram and cpu and heat sink. So as I use the display port in the gpu to the monitor I get no display however when I use the vga port on the motherboard for the integrated graphics I get a display, so to summarise my pc can’t recognise my gpu. Things I have done: - made sure the gpu is plugged in with the 6pin connector - tested another working gpu in the motherboard, and still no display (which tells me my gpu isn’t dead) - updated BIOS to the latest version. - reseated graphics card many times (and tested it into another working pc with display working.) - tried another monitor - tried a different port and cable (hdmi) - attempted to change graphics settings in bios to load pci-e only instead of the auto setting or integrated graphics however the changes do not save and automate change to auto again after rebooting. - 100% plugging display port in to gpu not motherboard. -updated and reinstalled windows 10 Reseated ram and tried one slot and multiple places. Pc specs: Graphics card: GTX 1060 3GB (asus) Processor: I7 7700k kabylake 4.20ghz RAM: Corsair vengeance 2x4gb ddr4 Motherboard: ASUS PRIME B250m-k Power supply: Corsair 450w psu Edit: I have just bought a brand new motherboard and still get the same problem. running out of ideas. Edit 2: tried another psu (600w) and still the same problem,could the cpu be the problem?
