Question Asus B560M-Plus WIFI - swapped GPUs now no Video, Mouse or Keyboard

[morrise18]

Hello, I would appreciate any help with this. I am somewhat of a novice but trying to learn.

I swapped my 2070 Super with a 4080 on the ASUS B560M-Plus WiFi motherboard. I used the PCIE 4.0 slot (the one with metal slots right next to the CPU). The GPU has 3 x 8-port PCIe cables that go to the 1000w PSU (only a year old roughly). Afterwards the computer will start, the video card lights up, the motherboard lights up and all the fans run but there is no video output and the keyboard and mouse don't light up or do anything. I have 2 x 16GB DDR 4 ram in slots 2 and 4 (grey slots).

I have tried removing the CMOS for a couple minutes while powered down. Reseeded the card and the power cables. Bad part is I put my old GPU back in and it does the same. I also tried powering it up with no GPU and using the onboard video but it was no good. (I have a 11700k CPU that can do video).

If you help me figure this out I will buy you a steam game of your choice for $40 or less (CAD$), this is how desperate I am. Haha.

Check to make sure the video cable is still connected on the back of your monitor. If that checks out then it sounds like the motherboard took a hard hit. It may need replacing. If that does not fix the issue then it could be a cpu issue. I have looked up the spec and a 1000w power supply is more than enough. The top PCIE slot is the right one. Also if you are using the adapter that came with your card make sure that no wires are loose.

Good Luck!
