I've just had the Blue Screen and the message 'pfn_list_corrupt' and i believe this is a memory related problem. I'm using Vista 64bit with 4Gb Ram, 4 identical PC6400 sticks. I've set the voltage to 2.1v as suggested by the manufacturer but still get the occasional Blue Screen. I was going to run a memory test but don't know where to start. I've downloaded Memtest86 but the install file won't run. Any suggestions gratefully received.
Ran the diagnostics tool and it came back clean - no errors detected. Back to square one ! I read somewhere that there's a program which can test individual sticks, or is this the same thing as the diagnostics i've just ran ?
Although a pain,i can only suggest removing a pair of sticks and seeing if it's ok.If it is replace with the other two and work on a trial and error basis until you find the dud stick. If all combinations work then your memory should be ok.
i had a problem last year, vista mem test passed with all 4 ram sticks in, but when i tried it 1 by 1 the last (sods law) stick would lock up memory test halfway though the first run. as mrwoowoo has said it's a pain but should identify a faulty module.
