[QUOTE="pigoo3, post: 1563888, member: 56379"] Sounds like you are familiar with the problem & the solution.:) The special cable from OWC is one of the solutions I'm considering. And like you said…the blasting fans and failing AHT are two of the issues that occur if an "off the shelf" non-Apple HD is used. Since you seem to be interested…the other quirky problem I was having (but fingers-crossed) not at the moment…is a display issue. There are three cables that need to be disconnected before removing the display panel. One of them (of course) is the display cable. This is the cable with the "weird" U-shaped wire retainer that has the black piece of plastic tape on it (for easy removal). Let me first say that I know that this computer has been "opened-up" a lot of times…and the display cable connector/plug & the socket on the logic board have gotten pretty "boogered-up"!:( And so I don't think that this cable & socket are mating up as properly as they should. What I think is happening is…the display cable connector is being inserted too far into the logic board socket…and when I power-up the computer…I get no video (no backlight or anything). I was dealing with this problem all afternoon. Sometimes I would get video & sometimes not (VERY FRUSTRATING)! Then earlier this evening I had an idea of tugging on the display cable (after it was connected to the logic board & the wire retainer was in place). When I did this…I could feel the display cable plug come out of the socket just a tiny bit (less than a millimeter). And ever since (about 4 hours now & a couple restarts)…I haven't lost video. So fingers-crossed.:) So I've had two problems with this computer today (unrelated I think). The hard drive problem…and the display problem. So "knock on wood"…the display problem is under control. And hopefully the parts I need for the HD problem will solve it!:) Let me know what you think. Thanks for the help,:) - Nick [/QUOTE]
