Got this bluescreen overnight, tried rebooting several times, into safe mode, always restart after the Windows screen, took a stick of RAM out and it booted, is it safe to assume the RAM is the problem? 27 passes with memtest show 0 errors on either stick(come to think of it, does it test one stick at a time? it might only be DIMM1 that I tested), but I did get a BAD_POOL_HEADER which is also attributed to RAM prior to my most recent reformat. About to leave for work so no time for specs but with the general information I've given its safe to say its the RAM?
