White Artefact After Start Up

Just to say I'm new here so sorry if this is in the wrong forum.

Just after I type my password word in and the desktop appears I've noticed a white artefact at the top of the screen. This only happens once but it's still a bit worrying per session but it happens every time I log in.

Anyone know what this could be?

  1. Sure,

    i5 2500k CPU (stock)
    MSI P67-GD53 Motherboard
    XFX 7870 Tahiti LE GPU
    128GB SSD
    500GB HDD
    8gb RAM
    750W Corsair PSU

    The artefact looked like a bunch of parallel squares linked together with with lines at the top and bottom. Similar to the metal plates that you remove from your case when adding a graphics card.
  2. And it came up for just under a second an then went away. It only happens once but it happens every time I turn it on.

    Usually I would suggest loading up a benchmark and check temps in the process, however since it only happens in Windows (idle) there's probably nothing to worry about. It most likely is a driver hiccup.

    You didn't post your Windows version so I'm assuming it's 7 - In that case you could download the AMD cleanup utility which will remove every trace of your drivers, including registry entries http://sites.amd.com/us/game/downloads/Pages/catalyst-uninstall-utility.aspx and then install the latest drivers http://sites.amd.com/us/game/downloads/Pages/radeon_win8-64.aspx and see if that helps.

    Awesome, I'll try it out when I'm back home.
