  1. Here is your card:
    Its clocked at 590/1296,it seems you have OC'd it a little,return it to factory speeds and see if it helps
  2. He probably meant 1280x720, AKA 720P, a quite common resolution for smaller or budget LCD TV's.

    OP, sounds like your system may be overheating.
    Try running your CPU and GPU at their stock speeds and see if that fixes anything.
    If not, post back you idle and load temps for your CPU and GPU.
    Use GPUz for GPU temps and Coretemp or Realtemp for the CPU.
  3. I doubt temperature is the problem as PC Probe shows CPU temperature at 28 C and 33 on load... its pretty cold were i live
    and the GPU is at around the same temp also...

    Any clue what might be the problem?
