Tried 6 different RAM sticks - a different slot was used each time for each stick - no output onto monitor using dvi and vga cables, and 2 different graphics cards.
USB keyboard - works when plugged into laptop, but does not work in any usb port on the motherboard in question - keyboard lights don't go on.
It may be posting, however since no video output on monitor I don't know.
There are no beeps as computer turns on.
It's not a new build - it's an old build. The problem happened a few months ago. I'm thinking something may have changed some of the settings on the motherboard when it was connected to the internet.
Before the problem happened, the BIOS was latest available & years without issue.
Please advise?
