I have an HP DV 6000 that I recently replaced the motherboard due to overheating. It appeared that the fan cooling blades were clogged with lint. My understanding is the video card or CPU get so hot it cracks the solder around the video card lifting it from the motherboard. When I installed I used one of those cooper heat sink shims and I always use an external cooling pad. Is there any thing else I can do to help keep it cooler? I heard that it is a good idea to update BIOS I tried this but it did not seem to change anything. While it was updating the fan turned up real high for a min but then turned back down and has never turned back up even when I watch videos like you tube and can feel the heat coming thru the palm rest. Is there any way to turn fan on high all the time?
