10.8.2 does not like 2xGT120s
Mirror RAID is of dubious value.
Normally system maintenance as in Safe Boot, repair directory, etc.
Power Management (sleep, power on, etc) are getting to be more common but on 2008, not 4,1 2009s.
Force Shutdowns WILL corrupt the boot directory.
Clone or do a clean install and test your system with just Apple Mac OS basics.
And of course you bought ECC certified for Mac Pro DDR3.

Hi The hatter
Ok, I have two GT120s I will try to work just with one GT120 I got. I did a clean install with the default settings that comes with my mac when I bought it. I know that force shutdowns is dangerous, but I tried to restart it with commands and didn't works. I bought ram from OWC, that problem I am experimenting is before I upgrade the ram, so it couldn't be the problem.
I did try cloning the boot drive but there was a problem with the HDD, so I bought a new one and install a clean copy of OSX, I thought that, that could solve my problem, then I realized that it didn't solved because a still experimenting the problem.
I not really sure if the problem comes out with the 10.8.2, I don't remember.
Snow Leopard seems to be the most solid OS.
SSDs can be iffy.
Anyone's RAM can cause or be a problem.
But you said it started before those.
"problem with the hard drive..." is too general and really rare. You would have to have bad sectors or something and not been able to map those out. Any drive can ship that way (not just mapped out at the factory). Zero all from Disk Utilty is not guarantee to resolve those.
Also rare to have a clone not work, SSDs being likely candidate and finiky.

I forgot metion that one day I have install windows 7 with bootcamp and that fix the problem for a time, but it comes up again. In that moment I thought that could be problem of finding the bootable drive. It works for a while with a bootcamp unit in the mac.
I will going to buy a SSD in the near future, no budget for a SDD. Does my mac works with SDD with SATA III 6Gb o just SATA II 3Gb? I did some research about that, I do realice that my version of mac pro just have SATA II but many disscusions don't say about, if HDD and SSD with SATA III works in SATA II interface. I found that it works but it won't works as a bootable HDD, still dubious with that info.
I have always verify and reparir permissions of the hard drive, I'm going to try it in Safe Mode or Single User Mode.
Permissions in your case are basically useless. I was talking about the directory that you are corrupting over time.
There are too many threads about SSD - they work is all you need - by goodness goes back 4 yrs already using SSDs of all shapes and sizes.
I never put Windows on same drive as OS X.
Reset the control panel in Windows or Mac for Startup Disk and make sure it is set to what you want (move away and back even).
If you have Lion, use Recovery Mode. If not, boot off a clone. If not a clone, make a small 30GB emergency Mac partition - on another drive (timemachine is actually useful place).
