Mac pro 5.1 power problem

[kakaduat]

Hi, my mac pro 5.1 went dark, no way to start it again.

As there is no mac repair on my island, i brought it to the local tech shop.

After changing the power suply it worked, but always only for 60-90 min, then its dark again.

Has anybody had the same problem AND a solution for it?

Hello,

This could be related to over heating as well - have the tech inspected the CPU heatsink, GPU and other parts on the unit?

Thanks,
i will take the mac home today and check myself.

Small hope that its something they could not read as the language on the mac is german and the tech is in Malta.

Any red lights staying on in your Mac ? And did you download a copy of Bresink Hardware Monitor and check the temperature of your components ? Could be a heat issue , which would shut down your Mac after a while .

maybe the heatsink on the northbridge became loose?

I just repaired a Nehalem NB heatsink yesterday before it went critical , so maybe . Bresink HM will give us an idea if any of the system components are overheating . Northbridge would be one such component with a sensor report in HM .

Why don`t you change the language from German to English or Maltese? It can be done through System preference, then select Language & Region - & add language.

Have it back now, new power suply but same problem as before:

If i connect it to power, on the top left of the vertical board the 2 leds for cpu a and b are on for half a sec, then nothing.

On/off switch gives no reaction.

Is it possible that's the power switch's problem?

Thats my hope, had it open but unable to get to the switch, i am a user!

Found a Apple service on the main island, will bring it to them tomorrow, that means a whole day wasted.
