On random occasion, the image on my screen will become extremely distorted for no reason- and in some cases these glitches can be reversed simply via changing the monitor configuration from 2 monitors to 1 monitor and back, or to the extreme of having to reboot the computer, interrupting my work in a serious way. Luckily, these errors rarely occur, but i cannot have my GPU gradually get worse to the point where it doesn't function to my needs.

Situation 1 Screen configuration

The monitor the above glitch is being viewed on is a Benq Widescreen monitor (no idea what the resolution is / can't recall). The shot above was taken earlier today, but i experienced this error earlier over summer too, and before that time, soon after i installed Windows 7 onto this computer for the first time (mid last august I screwed up the operating system a bit and re-installed it, and with that, reinstalled the drivers for my GPU). I'd also like to note that the left part of the affected monitor has somewhat of a line pattern on it (image below) The application currently on screen is the League Of Legends client This also happened with the monitor I was previously using, which was square like my secondary monitor. I Will also note that this does not effect my second monitor. The only solution that I can find to this problem is essentially shutting down the computer in some way, be it either by sleeping the rig or actually shutting it down and turning it back on. The computer operates completely as it normally should save for the screen glitch when this is occurring, and It doesn't crash any applications when it happens.

Situation 2 enter image description here These random stripes are pretty much the same as the last situation- save for what the problem is. The shot above was actually taken last july, before i reinstalled windows. This glitch actually crashed the instance of photoshop that I had open at the time, but thinking back on it, the graphical error could have been caused by photoshop crashing in the first place. Again, the glitch here could only be resolved via reboot. Not much else to say on the matter. (Pardon my camera's Phone's flash >_<)

Situation 3 (wasn't able to capture this error...) A couple nights ago I opened up a right-click menu, selected a menu item, and continued as usual- BUT, the selected item kinda stayed on my screen where I selected it. Any GUI elements behind it still work, and this lingering menu selection seems to be non-effective to the computer. Truth be told, this could have been from the computer being on for a long duration, and I HAVE experienced it on other computers before in the past (the other two errors occurred when the computer hadn't been on for much longer than 1 hour- hardly a duration of time in which it could overheat or anything). The remedy for this situation I found was simply switching the monitor config and then back, but as soon as I open up another drop down menu and select an item on it, the error occurs once again. I have seen this lingering GUI Element glitch with other things, too- Toasts, Tooltips, Etc.

Computer Specs: -Dual Intel Xeon 3.2GHz 8 Cores each -XFX Radeon HD 6870 1GB 900MHz -4GB -2TB 7800 RPM HDD

I Am using an AMD GPU, Yes, and I do know that their products are not quite as high quality as NVidia products, but my current GPU has been serving me very well for the year or so I have had it, and I sure did pay for the quality. Its an XFX card, too, and to those who are not familiar with the brand, they are one of the best hardware developers on the market.

EDIT~ adding the information @psychogeek asked me to put on here.

The left monitor i am currently using is set at 1680 by 1050, and the right monitor is set at 1280 by 1024. The one on the right is actually plugged into the Monitor 1 Port on my GPU, meaning that the left monitor would be plugged into the 2nd port. Both are using DVI as their connection type. The left (second) monitor is set to be the main display, with the right (first) monitor extending from the other one. I am not using Eyefinity in this configuration, despite being able to.

All of the 5 fans in my computer are operating fully and always have been, since the purchase of this computer. I am quite sure cooling/overheating is not a problem here.

Edit 2~ added a bit of information that may be useful for some of you.

None of these situations could be captured via the screen capturing tool. The first one was able to capture the desktop, but captured it just as the desktop would normally be displayed without the glitch. The Second situation also couldn't be captured. The third situation captured the desktop normally as it would without the lingering GUI elements- they seemed to overlay everything when they occurred, I suppose including the screen capture selections.

    The 2 screens shown look like sync errors (minor digital ones), there is a small possiblity that could have occurred at a monitor that got confused. You supplied really good info. Could you continue with 1) do you use eyefninity? . 2) what is the res of each monitor? . 3) do you switch monitors in software (clone, extend, one only eyefinity) often , or only when having a problem? . 4) what is connection type (dvi DP hdmi) to each monitor? . 5) did you ever test fixing it by cable remove and replace ? Did you since check your fan? – Psycogeek Oct 4 '13 at 10:16

    this could also be faulty graphic RAM. Try this tool: mikelab.kiev.ua/index_en.php?page=PROGRAMS/vmt_en – magicandre1981 Oct 4 '13 at 15:40
  • @Psycogeek Im almost completely sure that its not the monitors that are the cause of the problem, though I'll look into that more- and thanks :D I'll ad that info right now. – Ben Franchuk Oct 4 '13 at 22:16
  • I have the same situation and for me it happens randomly between 1 hour to 6 hours apart my monitor sometimes even goes into red mode / blue mode and other modes where it gives priority over a certain color and others not.. I came to understand its a LCD monitor problem since I just built this computer and I had this problem on my own computer and it transfered over with my new hardware new GPU etc.. sometimes my monitor even does a scroll effect with my whole desktop sometimes it shows picture backwards all kinds of crap.. new operating system too btw. so ya just letting you know it might be. – SSpoke Jan 22 '16 at 8:53
  • nope, it's not my monitors. I've since posting this question upgraded all of my monitors many times and i still experience these issues from time to time. – Ben Franchuk Feb 3 '16 at 21:05

no one mentioned the power supply , that would be my first guess , my screen just stopped working with the gpu connected but started working when disconneted (using gpu on cpu chip) and it took me a while to guess it was a faulty power supply.

    Definately not the power supply. I was first using a 2100 Watt PSU when these errors occured and since the original post I changed my PSU to a 1700 Watt (I think) and I've had this problem again since that. – Ben Franchuk Oct 5 '14 at 1:19
