Hi, Ive just purchased a new to me 2011 Macbook pro from ebay. Initially i got three beeps when i tried to turn it on. I got over that by resetting the ram, however now it when i turn it on i hear the fans and hdd kick in and I briefly get a white/grey screen (no logo or anything) for 2-3 seconds then it shuts off (can hear fans and hdd shut down) then the process starts again.
However if you hold the powerbutton down, it will book into Windows soon as you release the power button it turns off and the keyboard wont respond.

Is this likely to be a faulty motherboard? Any advice?

Sounds like a bad RAM module.
You could try to install only 1 of the 2 RAM modules and see if it boots.
If not, try with only the other module installed.

What happens if you boot to INTERNET recovery?
That's "command-OPTION-R" at boot.
