Mac pro 2006 not working after changing ram

Hello,

I have a mac pro 2006, and it worked fine untill i noticed that not al the ram was found.

So i turned it of, changed the ram by following a guide, when i pressed the power button i heard a short circuit electic noise.

From that point it didnt do anything. I have already tried removing everything, putting the ram back, using 1 stick of ram.

I am afraid the PSU(powersuply) will be dead. These are a bit expensive, i got the mac jesterday, so i hope i can bring it back to life without cost's.

Answered! View the answer I have this problem too

Is this a good question?

The main symptom of the first Gen MacPro power supply failing has been intermittent restarts. This gradually increases in frequency over time. Also the RAM is picky about how it likes to get installed. Apple put out a pretty comprehensive guide on this.

You said you got it yesterday. Where did you get it from?

The RAM might be mixed speeds and or brands or the RAM might not be supported. Use a spec sheet or the app Mactracker to see supported RAM.
