This is still my primary system. Bought it in July 2011. Replaced keyboard, battery, power-brick, hard disk and later upgraded to 8GB RAM & 256 GB Samsung EVO SSD. Changed thermal paste once. Did the genuine upgrade to Win 10. It was working rock solid till last month when Windows 10 decided to obsolete the AMD graphics driver in an update. There has been BSODs since then. Re-installed windows, still the same.. Thinking to downgrade to Windows 7 now..
