Hi, this is the first time for me in the forums.
My problem is that im getting an error in the system management, the problem is with my graphics cards, I have two EVGA GTX 780 running in SLI, a bought this cards a couple of months ago, for weeks there was no issues, then I sold my display for an economic emergency, for a month I did not use the computer, I manage to get an spare monitor from my office, when I connect the computer again it show me an error, about windows not loading properly, since I only use this computer for gaming I decided to format the computer, at first the installation went without problems, when I tried to install the drivers for my video cards I lost the Video signal in the monitor, I did restart the computer, again not video signal, I check de LED for the VGA but it was off, then I check for other LEDs in the MOBO, nothing, I decided to format the HDD again, the installation went without issues, this time I check the system management to see if there was a problem in any part of the hardware, then I see the "Error code 10" in one of the video cards, I tried to install the driver for that video card in particular, windows was unable to install the driver. I don't know what is going, I tried everything a read on forums, flash the bios to the latest update, reset the MOBO, reset the CMOS, use only two sticks of ram, remove the CPU and put it back again, install all the updates, the services pack, I tried with only one card to see which one was causing the problem, both cards function properly, when I connect the cards separately and check the system management the cards appears without issues, but when I connect the two cards the system management shows one of the cards with the problem, then I tried the cards in other system, with a different mobo a P8Z68V-PRO, and the same PSU, both cards running in SLI without problems, I don't know if this is a problem with the MOBO or the graphic cards, and the weirdest part is that I used the cards in SLI for many days before I sold my monitor, I run out of options, Please help!!!
