Hello, I built a new PC a few weeks ago with a B460 pro4 motherboard. If a display port cable is plugged in the PC doesn't boot. The UEFI is not accessible, 5 beeps can be heard and the fans turn.
This drove me crazy for a week because the PC would work fine when i took it to professionnals (because they used HDMI cable) but not at my home. Other than that there is just one time where my PC made 5 beeps but started anyway without problems.
It's not the end of the world if i can only use my PC with HDMI so my question is : Does it mean that my motherboard is faulty or is this a known problem? Could there be a fix?
Here are the components of my PC
new parts :
B460 pro4
intel 10700F
2*16Go ddr4 patriot viper 3200Mhz
ssd nvme WD sn550 1To
old parts :
GTX 950
2 old samsung HDD
creative X-FI soundblaster titanium
My screen is a 24G2u/BK and i have used it together with the graphic card and displayport cable for months. They worked fine together. Thanks.

Well just get an HDMI cable(my choice) adapters are available. Is the cable you have known to be good? Possibly a bad port on the board....
