Whenever I hit the power button on my machine, it takes 10-15 seconds for the beep sound to come, and there in no video signal-just a blackish-gray screen. Sometimes it simply doesnt POST at all, rather like a machine which has been OC'ed too far. Should I replace the GPU under warranty? It it linked to the grey areas which have started appearing on the PCB? It's barely 2 weeks old.
