I have this Alienware 17 laptop with the VAS00 LA-9331P REV 1.0 motherboard that does not turn on anything when power is plugged in and gives the 7 beep sequence, CPU / GPU does not heat up, i tried only with an I5 4200M (the laptop did not come with either the GPU or the CPU, but on the back says that it originally came with the Nvidia 860M and an 4710MQ).
While i do not know if there is any CPU blacklisting system on the motherboard, i tried reflashing the BIOS (at UH14) and the EC (at U2) accordingly but no changes either.
PCH doesn't seem to be shorted but i haven't done...
