Ok, it is not dusty at all, but I think I should inform you that I have sent my computer to a "lab" (I don't know what you call it :) ), to get my ex-high temperatures - problem. the temperatures would get to 80 C just like that.
and they told me afterwards that 58 - 62 C (kinda) is its natural temperature.
and by the way, the problem I told you about did happen alot before I sent my computer for fixing.. I got used to this problem so much I didnt even ask them to check it... so stupid. :)
so I think it doesnt have anything to do with temps.
and it is also not a complete freeze!
I can still open up folders, but not access any program. If I have a chrome page running, I can sometimes continue to surf on the same tab, but not open new tabs. and I can't get to the task manager, and I can't even turn off my computer! only with the reset button. I hear its not healthy for the computer
I hope this information helps
