Well, my HP laptop is like "pro"-series (:D), but it still can't pass SVPmark at FullHD settings with GPU on.
And it's an i5m + AMD 6450 - just a half of your hardware.
Modern laptops are very low quality and are designed for just a few years of life, that's why they're so cheap.
I dunno may be in your case some capacitor on MB started to degrade because of high temp or some chip lost contact like in earlier xbox 360 models.
And may be you've just placed it on a soft surface ![]()
