Hi every one, I have Acer B36H4-AD motherboard but the pci express slot dont working, I install graphic card gtx750 ti , I hear 2 beep sound, after that it start with the integreted graphic card.
- I tried my graphic card in another computer and it worked fine.
- I updated my bios same problem.
- I clean the pci port same problem
- I open device manager and the graphics card is not shown there either.
