I have no idea what to do

My crosshair v formula-z is acting strange. I had my PC done when it randomly started to not boot correctly. On its two seven-segment diaplays it'll say things like "5d," "68," "79" or "9a." It also randomly boots correctly. Please help.

Don't have any experience with this, but check the instuctions book for the 5d... stuff. You could also try flashing the BIOS.

yes try an bios update first to the latest version, if you keep having problems, then please send it back for rma
