Hi all,

I have a problem i hope someone may be able to help or give some pointers. I have a problem with either the graphic card or monitor in my computer.

The problem is that when trying to turn the screen back on by moving the mouse after windows switches is off after 15 mins, all i get is a screen full of purple and green lines about an inch wide each. If i move the mouse round the screen the icons and taskbar appear, but the lines remain on the screen. I can press the "show desktop" at the bottom of the screen which brings everything back to normal, but this is happening each time the screen goes off. I have tried searching the forum for any tips on this but have not found anything. Could this be the start of some sort of failiure of the monitor ? I don't have another monitor or graphic card to try to rule out which is causing the problem.

The card is an XFX R9 270, the monitor is a Benq G2220 HD.

Thanks

CPUID has never been very accurate for me (used to show my 12Volt rail at 8Volts, even though the PC was running and I was gaming on it.). Try...
What happens if you use the monitor's power switch and turn it off for 5 minutes, then back on?
You probably already know the first think to do is plug in another monitor and see if the problem persists; even if you have to buy one, try it, and return it if the problem doesn't go away. It could be the monitor is dying.
Do the monitor check first, because spending hours troubleshooting your video card only to find a bad monitor will really suck.
If the monitor isn't the problem, try this first with the video card: Download and install MSI's Afterburner program or EVGA;s Precision X program and create a fan profile that is a bit more aggressive then standard. Friend had weird stuff happening on his Dell monitor (Pink screen) and we tracked it down to bad cooling (and not much, just a little). We installed Afterburner and set the fans to spin up a bit earlier and the problem never re-occurred. His PC wasn't cooling fast enough soon enough..
If that doesn't work you should try to borrow someone's video card. OR if you have integrated graphics on the CPU, try that and see if the problem is gone.

Hi,

Thanks for the response, if you turn the monitor off for 5 mins and turn it back on it works fine, it is only when windows switches the screen off after 15 mins it causes the problem.

Trying another monitor would be my first port of call, but i don't have another one available, I was thinking of buying another to try out, but wanted to see if anyone by chance had encountered this problem before.

Could it be the fan profile ? I can try that, although I have CPUID HW monitor running and the graphic card never seems to get very hot according to that, it runs at 31C on tickover.
 
I used to also encounter this, it was due to the monitor. This does not mean a new monitor will fix the issue, but a suggestion to say it may be the issue.

As also listed, if you have integrated graphics, try that. You may find if you do have it, a valuable possession to locate the issue.
 


CPUID has never been very accurate for me (used to show my 12Volt rail at 8Volts, even though the PC was running and I was gaming on it.). Try HWInfo64, seems more accurate. The temp sensor on the video card may never display or indicate the temperature of a single small part of the card that might be getting to warm: So setting a fan profile that starts spinning up the GPU fan at a lower temp might help.
While you are figuring out how to swap monitors (at least temporarily), you might also try a complete uninstall of your video card drivers and software, then reinstall all the latest drivers. It isn't often, but over the years I have had drivers so messed up that I had to do this and even go into regedit and remove everything I could find that was associated with my video drivers.
Keep us posted, please.

Hi,

Fingers croseed the problem has been resolved. I decided to wipe my SSD and start from scratch reinstalling everything (this was always planned and wasn't just to try to resolve this problem, but seemded like a good time to do it). I have removed and re-seated the graphic card just incase and installed the latest AMD drivers.

So, although i'm not sure what resolved the issue, the problem has not re-occurred so hopefully all is good. Thanks to all for the suggestions.
