Computer on multimonitor setup "hangs" with seemingly randomly colored screens.

Hi there. I'm on a 3 monitor setup, so I'm going to say the symptoms and then my specs.

I was just on the internet or something this morning when everything went crazy. My left monitor turned purple, my middle monitor turned white, and my right monitor turned gray (an active gray, not an "I'm getting no signal" gray). So I turn off the computer and turn it back on again.

Normally, when I turn on my computer, the following things happen:


  1. Motherboard screen shows up on the left and right monitor (with middle monitor remaining "no signal" blank)

  2. Windows loading screen shows up on the left and right monitor (with middle monitor remaining "no signal" blank)

  3. Middle monitor wakes up and shows my background/wallpaper/what have you so I can sign into Windows 8. Right and left monitors are actively black (I can move my cursor into them and it shows up on them, etc.)


  • Now, step 3 looks like this:

    1. Right and left monitors are "active" black (not "no signal" black). Middle monitor remains "no signal" blank. Moving the cursor to the left and right extremes yields no cursor display.


  • The exception appears to be if I do a "cold" restart (i.e. if I completely unplug my power supply and wait 10 seconds or so). Then everything seems to work, except the same issue may happen immediately upon login. As a side note, if I get to the login screen, I can always get past the login screen.

    I'm running Windows 8 off an SSD, I have a Radeon 7900 series graphics card, an Intel i5, and a Z87-G45 msi motherboard.

    Can anyone help?

    Note: Everything seems to be pretty fine when I just use a single monitor setup!

    Second note: I've been using this setup for weeks/months (the motherboard and CPU are weeks old, but everything else is at least a year old), and the first time I've run across these problems has been today.

    EDIT: More information:

    Safe mode with multiple monitors does not have the same problem, but it has other problems! Everything gets really warped and distorted, progressively so. It looks... for lack of a better word, staticky. It starts off completely fine, and then the screen gains blemishes (both static and dynamic; sometimes it's just vertical black bars, sometimes it's things jumping around)

    Best solution

    colors, random patterns (if all monitors connected to single source GPU), usually denotes video memory corruption. The first thing to look for to rule out is tweaked input cables on the monitors or at the video card and second would be to reseat the video card int PCIe slot. Both of those can cause similar symptoms. If neither is the problem then it points to video memory corruption. Also try driver update that won't hurt either.

    (also don't overclock, the couple of extra fps generally isn't worth the stress on your hardware unless cooling is significantly improved)

    Thanks for your response, warezme. I checked the cables as well as the seating, so I now believe that the problem may be video memory corruption. I checked for a driver update and there is none. My only trepidation about the belief that it is video memory corruption is that the computer seems to be working perfectly on one monitor. I don't really know how video memory corruption works. Is there a way to test that this is the case, and is there a solution to the problem?
