I have an Abit IT7-MAX2 v2.0 mobo. It has 3 mem slots. I have successfully for several years run two 1-GB mem sticks (Crucial) - one in each of slots #1 and #2. I have a mem tester that i downloaded from microsoft. it is a bootable cd-rom often referred to as "mtinst.exe". I recently began seeing the blue screen, ran the mem tester, receiving many errors. took PC to a shop a couple times. the technician never questioned the memory. He finally flashed the bios, and the PC was OK for a week or so. then the blue screen returned. I ran tester again. The tester dies consistently at the same time during the "stride-6" portion of the test.
I removed the second 1-GB mem stick, leaving the first 1-GB mem stick in slot one. mem test ran fine going successfully past the failure spot. I swapped mem sticks to repeat the test on the remaining 1-GB stick (with no other stick in place) in slot #1. the test ran fine. Next I left the current 1_GB stick in slot #1 and placed the other (which had tested OK minutes ago) in slot #3, hoping there was a problem maybe isolated to slot #2 on the mobo. this test failed in exactly the same spot - during the "stride-6" subtest. the failure symptom, again, was that the tester died.
One time the blue screen reported trouble with the DLL file "atidvag". I have a Radeon 9550 video card. i read a bit on the net, and went to ATI site. i downloaded and installed latest driver set for this card. blue screen still returned.
the blue screen occurs from ten min to 1 hour after boot at times when i am calling heavily on the memory, by the way.
I think the mobo is at fault, but i am not sure enough to spend the money without advice. maybe something else i am unaware of could cause these symptoms. The technician, however, said he found no hardware faults - power supply, e.g. i would appreciate any opinions.
