[I have searched the forum! Sorry if its already covered.]
I've had my Shuttle SN85G4 since September. I've had niggling problems in the past but nothing that could not be solved. This time seems different and I'm at a loss for what to do. Unfortunately to add insult to injury, this is the time where I am having to hand in alot of major uni projects and not having a system I can work on efficiently is driving me nuts.
My problems began a while back, I noticed a fan in the Shuttle was unusually noisy. I don't know if this event is related. Out of the blue a few days ago my Shuttle just powered off. Straight to black screen, no shutdown message or anything. Since then it has been continually doing this. I sense the problem is over-heating due to the fact that if I turn on the system immediately after it has shutdown, it will last only a few seconds before it does it again. In my opinion the Shuttle is shutting itself down before it gets too hot. I may be wrong.
Having cleaned the dust out of the system completely, rebuilt it in terms of removing the components and putting them back in again, nothing seemed out of place. I have just noticed however that the intake fan on the back of the unit is not spinning. A strange occurance obviously I have attempted to unplug and plug the fan back into its 3pin connector to no satisfying result. I have since removed the fan from the system and plugged it into another 3pin connector on a different machine. It worked.
My intake fan has stopped working, yet works on other machines. How can I resolve this? Am I stuck with a dodgy motherboard connector and is there nothing else I can do but to RMA? It seems to drastic for such a small part...
Please help! I'm going insane thinking about resolving this problem.
