Hello all, I'm fairly new to this site and am looking for help regarding a recurring desktop issue. I'm not very computer savvy, so I'll ask that you bear with me if anything I say comes out a bit derpy. I would greatly appreciate any help in regards to the following problem.

I recently got a new dual-monitor desktop built by a friend and it worked fine for the first week or so. A few days ago it started getting hectic whenever I tried to turn it on, in that it would frequently do one of two things:
1) The screens would both go black and post "no signal"
2) Both screens would freeze in place and it would recognize no actions aside from turning the desktop off
The "no signal" issue only appears when attempting to log in or right after turning the computer on, whereas the screen-freezing would happen at any given time, whether it be logging onto the computer, checking facebook, or playing Diablo III. It currently takes me 3-4 attempts to get it running properly each day. Everything in the computer is new, so it shouldn't be a problem with bad cables connecting the monitors to the tower or the ports that the cables are connected to. I've tried moving the cables to different ports on the tower, and it doesn't really seem to be affecting the problem. Nothing is out of place or unscrewed inside the tower, so it's probably a software issue. The same friend that built the computer suggested that I get the latest nvidia drivers since the most recent ones were available on the 14th, whereas my current nvidia drivers are slightly older. I tried downloading the most recent one, but then I received the screen-freezing problem. Whenever I attempt to download anything video-related online, the comp simply freezes up again. I can play youtube videos and Diablo III fine, just not download anything significant off the internet. My friend tried working with the comp as well, but he's at his wit's end and suggests that we get outside help in diagnosing the problem, so he recommended this site.

I'd be grateful for any advice in tackling this issue.

Computer specs are as follows:
Windows 7 Ultimate (Service Pack 1)
Intel Core i7 CPU
64-bit OS
x2 GTX460 video cards
12.0 GB of RAM

Hello and Welcome to Bleeping Computer.

I have some questions about the dual screening

Do you have the exact same models for your monitors or different monitors. Try setting the "Native Resolution" The Native Resolution is the recommended screen size.

Are you cloning or Extending the Desktop

I see that your SLIing two GTX460 cards.

Do u have Two monitors on a single card or one monitor on each card?

Both are x203h 20" acer monitors.

The desktop is extended.

I believe it's one card per monitor, but I'm not entirely certain.

Did you put both monitors on the same card so you won't have conflict. Try that configuration and see if that helps

Go to Here: http://www.geforce.com/hardware/technology/sli/system-requirements

I inputted your configurations and the max resolution is 2560x1600 per monitor

So you under the max resolution with 1600x 900 per monitor

http://support.acer.com/acerpanam/MONITOR/2010/Acer/X203H/X203Hsp2.shtml

Are you using DVI cables
__________________

To checck the Screen Resolution

Right Click on the Desktop
Go to Screen Resolution
Click Detect

The Display drop down will be the same type of monitor
Click Resolution until it says 1600x900 (Recommended) on both Monitors and click Apply

See if that helps

I cant see why your getting that problem unless you set it as a different refresh rate

I checked the resolution and it's already set to 1600x900 for both monitors and the refresh rate is the same for both monitors, as well.

I'm currently using two DVI cables - one per monitor.


This is a bit tangential, but under Control Panel> System it's saying that there is new hardware detected and that my Windows Experience Index needs to be refreshed.
I tried refreshing it earlier today, but it simply froze the screens again. Same result with attempting to install the latest nvidia drivers.

Did you install the drivers on the CD yet or Are you using the Microsoft Default ones

If you running the driver you should see Nvidia Control Panel on your Right Click menu.

Do you have any Drivers that have a X or "!" in the device manager.

Let try this disable one screen and then download the drivers from the manufacturer website.
