My PC is fairly new, it never happens when watching media in full screen or playing games, I thought it was my old gpu but I replaced it and the issue persists. Usually it happens when I am browsing but it has happened when in normal folders, etc...

My monitor disconnects for 1-5 seconds and then reconnects without any reason, I have ran memory tests and cpu tests, now I am thinking its the motherboard, my specs are: Windows 8.1, 8gb 1600 DDR Corsair Vengence Ram, i5 4960k @ 4.4ghz, AMD 290x, EVGA G2 750w PSU, Wifi Card(Forget brand), Asus Z97-A Motherboard.

What could be causing this, what should I check? I have checked with multiple screens, dvi and hdmi both have this issue. I tried reinstalling Windows also twice, no luck....


I built this PC myself, have been building for years, never encountered something I could not figure out, go figure its my most expensive build yet....ugh, any help would be great.

Do you have any hot keys on your keyboard that allow you to change video settings? Maybe you have a stuck key or sticking key. If you have a spare keyboard, you might try unplugging your current keyboard and trying a different one. Screens will flash/disconnect for a few seconds typically when chaning resolutions or other settings related to screens etc... That might be one cause.


If you have not already done so, update your video card drivers directly from AMD's website: http://support.amd.com/en-us/download


Another thing to try would be a linux distro, something like linux mint, if the same issue happens there, I would then lean more toward a hardware level issue. You can get linux mint here: http://www.linuxmint.com/download.php


What cpu tests have you tried?


Lastly, please download and run speccy:


  • Go to Piriform's website, and click the big download.png button.
  • Next, click Download from Piriform.com (the FileHippo link requires an extra click). Or if you want to use a portable version of Speccy (which doesn't require installation), click the builds page link and download the portable version.
  • You will now be asked where you want to save the file. The best place to put it is the Desktop, as it will be easy to find later.
  • After the file finishes downloading, you are ready to run Speccy. If you downloaded the installer, simply double-click on it and follow the prompts until installation is complete. If you downloaded the portable version, you will need to unzip it before use. Right-click the ZIP file and click Extract all. Click Next. Open up the extracted folder and double-click on Speccy.
  • Once inside Speccy, it will look similar to this (with your computer's specifications, of course):
  • Now, at the top, click File > Publish Snapshot
  • You will see the following prompt:
  • Click Yes > then Copy to Clipboard
  • Now, once you are back in the forum topic you are posting in, click the p22004370.gif button. Right-click in the empty space of the Reply box and click Paste. Then, click Add Reply below the Reply box.
  • Congrats! You have just posted your specs!

If I am helping you with a problem and I have not responded within 48 hours please send me a PM.
