My questions and doubts:
1. How can it be solved?
2. Can we call this “overheating” since it freezes when temperature is not over 60 C? but it freezes more when the weather is hotter.
3. Is the temperature during safe mode normal or too high?
4. Am I abusing my laptop?

Please request information or pictures if needed more, I am willing to provide.

Problem history:
It works fine with Windows 7 since 2009, when I’ve been recovering from spine surgery, I’ve been using it more than usual since December 2011 where the problem occurs first time, then it occurs more often since March 2012.

Computer usage behavior:
I usually use Autodesk Inventor and Autocad software for 3D and 2D designing, along with web browsing, playing music with iTunes, watching some concerts and South Park by windows media classic. I play occasionally play games like Left 4 Dead 2, Elder Scrolls Skyrim (once-twice a week).

The laptop is placed on a 30 degree inclined stand, due to my surgery I need to only lie down to use the computer. It is turned on about 4-10 hours a day.

Observations:

It’s been working fine since bought, when I play games, the temperature of CPU and GPU goes up to 75 C for about 1-2 hours, no problem, usually I don’t play longer than 3 hours.

Since March, it freezes randomly about 1 hour after startup when I’m using designing software along with web browsing. Temperature is about 48-53 C, I have screenshots of the temperature software before it freezes. This happens at least once a day.

Since March, it freezes about 5 minutes after start running left 4 dead or skyrim.

During safe mode, the temperature stays about 70 C and sometimes freezes.

After forced shut down and power on right away sometimes it freezes during boot, or even 5 seconds after power on.

It rarely freezes when watching videos and when turning the computer on all night for downloading.

I never finish a full system virus scan, it freezes about 20 minutes after scanning while temperature is about 50 C.

Weather condition: Thailand, hot and humid.
No air conditioning in room, temperature during of months Dec-Feb: 20-30 C, Mar 30-35 C, Apr 35-40 C (hottest of summer). My laptop in this temperature works fine in the past 2 years, other older laptops are also working fine.

Suspected causes and solutions tried:
Replace thermal paste at CPUs and GPU, dust removal at CPU fan, got a cooling pad underneath laptop: temperature slightly drops (3-5 C), no significant improvement in freezing.

Tried updating drivers to the latest possible for the right OS, reformatted partition to change OS to Win XP but problem still occurs.

Thank you,

I have found people complaining about the freezing when using Autodesk Inventor and Autocad software for 3D and 2D designing but then that happens mostly during rendering, i think that your system is having virus as from what i have read your system is freezing frequently, i don't think that there is any thing wrong with the temperature. i will suggest you to better try out scanning the system in safemode and see if the scanning process is getting completed or not.
