Don't know what to do

Hello

I have a MacPro 2.66 dual 10.7.5 running, lately it started to freeze on voltage on very shortly after.

I ran Techtool pro and he has not found something wrong with the disk, memory, etc. When I start the machine Ical for a reason some starts and it crashes. I look into suggestions and it isn't pre loading it. What is happening is the fans start to the race and the machine looks black starting from the top to the bottom to the top of the screen or I get the dreaded your machine crashed hold down the power button to turn off.

Q1, this could be a software problem and the need to reinstall 10.7.5?

T2, stop waisting my time and update my Mac Pro?

Note: I am a professional photographer and use this machine for almost every day and a heavy user of Photoshop.

To do a used mac pro 5.1 machine.

Thank you

Martin

• Record the time of the next unsuccessful boot. After the reboot, open the Console app in Finder > Applications > utilities and look for entries of the log at the time of reset. Suspicious message here.

Search before the journal entry that begins with BOOT_TIME since it is the first line of a startup

-After an unsuccessful start, open the side cover and look for the diagnostic lights illuminated on the logic board or the memory modules.

-Run and view the results here so that we know more about your configuration.
