    When i play games in fullscreen i get white horizontal lines flashing on the screen about every 30 seconds, i also get them in the game menu, tested on two monitors over VGA and HDMI. It happens at different resolution and different refresh rates.
    It doesn't happen when i play games in fullscreen-borderless and in windowed mode, only happens in fullscreen.
    I removed the drivers and installed a different version but it doesn't solve the problem.
    It happens more often when i have unlocked fps, the gpu is always under 50C.

    I think it's the gpu, what do you think? If that's the case i will upgrade in a few months.

    I have an i7 4770k overclocked at 4.4Ghz, r9 380 non OC, 8gb 1600mhz ram.

    Underclock your GPU - Test
    Underclock your memory - Test
    Underclock both - Test
    Play around with Wattman, raise voltage etc. also to see if you can isolate cause.
    Change frequency of your cpu/memory as well just in case it is a RF issue.

    It could still be issue with drivers and Windows install as well. So see if anything affects this behavior.

    I tried it but without positive results. I've booted from a backup disk with windows 8 and i didn't see any line for a few minutes of csgo, tomorrow i'll install the exact driver version on window 10 and play for a bit.
    All those driver releases and the only changes I've noticed are these white lines, less options for monitor calibration, more frequent driver crashes.
    thanks for the help I hope installing an old driver is enough.

    Wow, what a headach! - Now I did forget one very important one - cable - switch out the monitor cable, switch ports on the card as well.

    looks like your video memory might be going bad. I would suggest RMA it before warranty runs out.

    I've installed a very old driver and i don't see any unwanted white line. If the problem started with the latest driver why wouldn't previous versions work? I had to go back to a months older driver, but everything works for now.

    I don't think i can rma the card. I had ordered a 390 from amazon marketplace but they sent me the 380 and didn't allow me to send it back for reimbursement. I contacted amazon that refunded me and let me keep it, so i don't think i'm entitled to any assistance. I'm planning to upgrade in the next months anyway.

    They didn't let you send it back, but gave you a full refund and let you keep it? Am I reading this right?

    Also, that doesn't mean you can't do RMA with manufacture.
