Blue screen of death

Hi guys, i'm starting to get the BSOD on my system.
i think something is dying, just not sure what.
it happens quite randomly with or w/o load.
no recent changes to hardware or software.
tried both updating and rolling back gpu drivers
i suspect it's the RAM. is there any way to check?
im running win 7 64-bit.
Try the following:

Remove everything and try to run with basic parts - single ram, igpu if possible.

Also see if u can borrow a psu. random bsod with/without load is a classic symptom of psu failure.
