A chronically slow laptop was crashing without any event viewer log references. The crashes were happening when the user used google hangouts. She had updated all drivers. When I got there, the gpu and 4 cpu cores were about 80c doing nothing. I blew a lot of dust out of the vents in the area where the heat was coming from (from operator perspective, the far left corner of the laptop, on the side, and underneath). After that, the temps dropped to and stayed below 55c. And so far no crashes when user uses google hangout.
So it looks like it was dust in the cpu or gpu area, plus the age of the laptop.
What I want to know is -- where is the GPU, in relation to the CPU? Do they share a cooling system and heatsink? I could not find a diagram on the web.
It's a windows 7 home premium 64 bit laptop, one of the following (my notes don't specify which is the one above, sorry)
SATELLITE A505-S6025 SUPPORT
SATELLITE A505-S6980 SUPPORT
(PS - extra credit if you know of a free temp monitor app that does live recording of temp history, so the temps prior to crash are there when I restart.)
