Potential video card issues, anyone else experiencing this?

    First my specs:

    2013 13" Air
    Intel HD Graphics 5000

    I don't think anything else is relevant, but if someone is curious, I'll be happy to oblige.

    So from the get-go, I've been having some issues with my Air (although I'm not sure how related they are). Occasionally, when I wake my laptop from sleep, it won't wake up and I'm forced to reboot it. I've been having this problem in Mountain Lion and in Mavericks though, so I don't think it's related to the OS.

    Another problem I've been having is that when I have it connected to an external monitor, occasionally, when I switch the inputs from DVI (which is what I have it connected by) to HDMI and back, it presents a "snowy" screen, similar to what you would get from a tv without reception. This is remedied by just switching it back to HDMI and then to DVI though.

    This last problem is the one I experienced just today and is the one I am most concerned about. When I woke my Air up from sleep, I was greeted by a white screen with lines of different color going down it from top to bottom. My computer was completely unresponsive, and I was forced to reboot. What bothers me is that this could be a sign of the video card acting up...

    I haven't brought this into my Apple store yet because they happen infrequently and it's pretty difficult for me to reproduce them (although waking from sleep seems to be a common issue). Is anyone else experiencing this? Anyone have any idea what could be causing my problems and how I could fix them? Thanks.

    If it is still under warranty, bring it in to your local Apple store ASAP. Take a picture of the glitched out screen if possible. If you cannot reproduce it, just bring it into the Apple store and tell them about the colored lines. It could be a graphics card issue, and it will be very expensive if it is not under warranty.

    It's still under warranty. I'll be starting graduate school in the Fall, and I would rather lose access to my computer now then later, so I'll bring it in and discuss my issues with them. Thanks for the advice.
