Recently upon login, it bluescreens, reboots, then it works fine. Happens every time without fail now. No idea what the is causing it.

Checking against mobo manual, two operating lights next to memory are for working indicating, two for alerts (over?power and something. all 4 are on with 4 sticks, but it works, apart from that initial BSOD, go down to 2 sticks and the alerts go.

Couldnt be a power thing could it?
