Trying to get PC working with new motherboard
This is a Windows 10, HP Pavilion desktop. I replaced the motherboard because I suspected it was damaged.
My old motherboard was an HP Infineon-B 696233-001.
New model is AS IS HP P6 P7 Series Socket 1155 Desktop Motherboard 696233-001. I’m not sure if that’s the same, but all the pins were compatible.
On boot, I can hear the hard drive working, no beeping, but there’s no DVI signal. I tried with different monitor and monitor cables. I tried with and without a graphics card, and I swapped out the ram sticks. The machine stays on, but I can’t tell if it has actually booted the OS or not. The hard drive works fine with another machine.
What should I check next?
