Vaio VPCF119GX overheats, reboots often and takes time to turn back on

I bought a Sony Vaio VPCF119GX in the US and currently living in Asia. Since the beginning there have been symptoms of overheating and rebooting, but lately it's getting more and more usual. In fact it reboots everytime I play a game and gets super hot, sometimes when I'm not playing any games at all. I can't turn it back on immediately after reboot, but it turns on okay after a while. I contacted Sony support, they pointed me to a bios update but it said my system bios is up to date and need no update.
The situation is dire . Anyone can help? I'm more than grateful.

 

No one cares to help me?

 

What are the CPU and GPU temperatures? Normal and stressed. Use a monitoring utility like Everest (free version or paid), SpeedFan, CPU-Z and GPU-Z and run them in the background.

Are the airways clear? Often people run laptops on their laps and the clothes block the air intake vents at the bottom.

 

The VAIO F tends to not overheat when the vents on the bottom are blocked while on the user's lap. Were this the case, it would also overheat while flat on a desk. Though sometimes loud, the F has great heat management.

I've got 2 thoughts to add to the tools anytimer has recommended:
dust in the heatsink/exhaust vent
thermal paste gone bad/dried out

Your CPU temps (depending on your climate) should idle between 45 and 55c. Under stress, 65c is normal for me, but I'm in a cool area. 70+ is high and anything way over that is indicative of either of the above problems, or something else.

 

I don't have a VAIO F, just a VAIO VPCZ1, but mine has tiny little rubber feet on the bottom which keep it a little off the surface when it is resting on a flat, hard surface, say, a desk. This allows air to enter through the vents on the bottom. While on my lap, or on my bed, the vents on the bottom are not guaranteed to be unobstructed - I need to take care that they are.

Once we get an idea of the temperatures, we can tell him more. Maybe the fan itself is wearing out. Good points about dust and heat sink paste.

 

As you all see the temp is intense. I use a Cooler Master under the laptop so I dont think the problem is about ventilation blockage. Both of the problems anseio listed involved disassembling the laptop, should I take it to a Sony store or try taking it off myself?
PS: The climate here is obviously hot and humid, it's 2 in the afternoon and the temp is about 91.4 F.

 

Yeah, those temps are high. Very high. Since you're GPU and CPU are both running hot, I'm going to say that you've got dust buildup. Like dust filling the filter of a hairdryer. Slowly clogs up like lint.

You can disassemble and blow canned air yourself:

be sure that when you're doing this that you also blow air into the exhaust vent on the left side, from the outside. You might be gifted with dust bunnies coming back through the fan and out.

I doubt it's a thermal paste issue.
