Hi all, I hope this is the right place to post.

I'm having a problem with a Dell 9310 which is posting 2 orange, 4 white lights on startup (hangs on Dell BIOS logo). The service manual says its a RAM failure.

I've taken the motherboard out and noticed that one of what looks like an SMA 0805 resistor has blown (see photo). The board is an LA-J144P Rev 2.0(A01).

1] Could someone confirm what the component that has blow actually is (and where I could get another from).
2] Whether this component is likely to cause the RAM failure issue, and if replacing...
