new Vista machine 32bit we were getting a lot of stop errors typically related to memory such as 8E, BE, D1, 1A memory testing passed without reporting problems anyway, I swapped out the 4gb (2X2gb) with new sticks stop erros continue, mostly the stop 1A minidmp on 0xBEstop code showed process name svchost probably caused by memory corruption (nt!MiRemoveStandyPage+6F) attempted_to-write_to_readonly_memory how best to proceed? driver verifier? Graphics card?
