OK.
So i ran a windows chkdsk. Ran the Seagate diagnostic again, and the critical error found this time was only in the "metadata file records". Then i ran the full diagnostic (took like 4 hours). I would like to say at this point, that during chkdsk and diagnostics i DID NOT HEAR clicking. I find this odd, you would think during a HD intensive diagnostic...youd hear the clicking.
Anyways like i said, no physical errors were found...only an error in the metadata file records (during the file structure test).
Also, i said the clicking is not persistent...once now, maybe 15 minutes later maybe 10 hours later....so opening the case and putting my ear to it is isn't the answer. Its like a "triggering" sound, that happens pretty infrequently...but doesn't sound right.
As for the crash/error earlier. I forget exactly what it was called. BAD_PULL_ERROR or something like that....bad something...
Yes my HD is a 7200.8...
As for fans/cables hitting each other. My zalman and video card are well protected from cabels ( i have duct taped most of the cables out of the way). I can't see inside the Power supply....soim not sure if fans are hitting cables there.
Are there other devices that can click....almost the sound of taking paper clip/bobby pin/ and flicking it against metal or something...to things on the mobo trigger on and off?
Also...ive run 3 different mem tests and each has passed (including memtest86 for 8 hours)
