Sporadic freezing on 'Starting Windows' screen and on sleep

Not sure which part exactly tells you what you need to know, so here's the results of all 8 buttons from SF Diag Tool.exe and a new Speccy.

So I went ahead and disassembled the laptop down to the fans. The dust didn't look too bad, but I took a vaccum to it and put it all back together and WOW! I did a cold reboot 4 or 5 times in a row and put it to sleep using the power button and closing the lid and every single time it came back! I can definitely physically feel that the bottom is cooler, and here's a Speccy I just ran that shows the temps are way down. http://speccy.piriform.com/results/4...x7xPkunX5zKhN1

Thank you so so much centaur! This had been driving me crazy for more than a month! I'll still keep an eye on my temperatures but it really looks like it's solved.

Holy cow !!! neo those are cute little temperature...

Hope you had fun ripping you laptop apart....

and yes you are welcome !!

EDIT: try using some games to max the temps and see..if it spikes.. or use some cpu intensive programs to do the same... let me know if its on fire!!
