GPU can not work....

I used a GTX580 before. It worked good.

And today it Failed many times, and I am trying to use a GTX590.

But after I install it in my machine, the computer restart every time when I run Octane and click the object to use GPU render. I have tried many ways, reinstall the drivers, use one another GTX590, and reinstall the system. It can not work.

And there is another question, after I reinstall a new system, and install Octane render, why it can show the recent file what I rendered in the previous system when I run it first in the new system, it is so wierd!!!

Do you have enough power for the GTX 590? I remember when my PC rebooted after changing graphic card, the problem was the PSU not giving enough power.
The GTX 590 uses about 160watt more than the GTX 580.

me to thinks an insufficient or even dying psu might cause the problems. what are the specs of your psu, and how old is it?

thanks, I have found the problem, the power.

It works now.
