Hello, my Toshiba c660-1ch is shutting by itself, when i run a game. Before it shut down it turns hot, very very hot, then it shuts down, so i was wondering, is a laptop stand cooler will fix this or no?
Three things MAY fix it:

1) Placing the laptop on a flat table, with clearance from below / placing on a hole riddled table (bamboo for example)
2) Thermal paste reapplication for CPU / GPU.
3) Laptop cooler stand.

Usually all 3 will lower temperatures without exception.

Now the usual laptop cooling solutions are inadequate, coming with only 1-3 small fans. The real deal is to make one yourself. But 2 12cm fans and some balsa wood, and cut holes, etc... and run them either off USB or off an AC-DC power adapter (a quality one, not a cheap transformer).

If you study your laptop's cooling system carefully, you could make do with 1 fan, strategically placed.
mohammadk97 wrotehow much if is the stand cooler cost ?
I think they top out at 30 bucks but some don't even help...Some barely knock off 1-2C...it would benefit a lot if the fans came directly below the fans of the laptop...that way it would ensure some airflow...but still...DIY is MUCH better. Mine knocked off 15-20C...went from 85C under UT3 to 65-70C Prime95!
If you were placing it on soft surfaces such as beds, pillows, sofas, even ur legs, chances are it got pretty dusty in there. You can try opening it up and getting the dust off the fans and make sure they are working well. Other than that you need to reapply your thermal paste. Oh and update your drivers, that could sometimes help alot if the problem isnt completly hardware-wise, I've seen GPU's dropping 7C with driver update.
does it shutoff immediately ?
if it does than a cooling pad won't fix that
did you try blowing air to the exhaust fans ??
also if you have taken it apart before did you remember to replace the thermal-paste??
if not ROG just brought the Thermaltake MX-4 (costs 20$) you can use that to make it run cooler
Don't use the cooling pad if there was dust, because if there was, the air ventilation is semi reversed, using cooling pad or fan will limit this just like there isnt any fan... (If it was so dusty)

You should send it to a local shop for cleaning maintenance, only if you still don't want to avoid the warranty.

Note: When the BIOS detects overheating states, the BIOS tells the ACPI to halt. (After it halts can you run it again or you should wait? that explains the CMOS status logging...)-(Normally it would take 5 minutes to coll down and starts again manually).

Else, you should clean it yourself, check fan speed, use thermal paste for fast heat conducting (for long lifetime use the gold labeled ones). Goodluck.
I had the exact same problem....
Downloaded a "Temperature checker" tool, that warned me whenever cpu temperature reached critical level.
But i was on vista then, so i formatted and installed windows 7...
Problem solved.
Weird i know, but it worked
thank you all for your replys. downloaded a temperature checker, my average temperatur is 55 C:p, and i have a windows 7 home premium. And there is no dust, all clean. Going today to buy a stand.
Oh and update your drivers, that could sometimes help alot if the problem isnt completly hardware-wise, I've seen GPU's dropping 7C with driver update.
How do i update a driver? because at the device manager, when i update a driver it says it is all ready up to date, and i bought the laptop a year ago, and i haven't updated any driver.

That drop is due to a driver bug that reports the temperature 8C higher than the temperature reported by the sensor itself. That happens with Nvidia. Since overheat protection is built into the chip itself, I think it will tend to monitor temperature readings from the sensor and not from the driver.

We don't need average temperatures. Get a tool like Prime95 and run a torture test. If the temperatures approach 80C - 90C quickly, then stop the test. Then you know what the problem is.
TPR0 wroteuse thermal paste for fast heat conducting (for long lifetime use the gold labeled ones). Goodluck.
Gold labeled ones? First time I hear of that. Just get some quality thermal paste (MX-4) if you want to apply paste, and be done with it. Last thing I knew, Arctic MX-4, OCZ freeze, Gelid GC-1, Noctua NH-D1, Indigo Xtreme, and Coollaboratory Liquid Metal Ultra were the best performers in thermal paste, yet I can't see a gold label on any of them...

That's a BIOS update, isnt it? Not a driver update. It only helps if the BIOS is misreporting the temperatures reported by the sensor, which is like, never.
AvoK95 wrotedoes it shutoff immediately ?

Thermaltake MX-4?? :P Ya3teek l 3afye! It's Arctic Cooling MX-4 :D

Sorry, forgot to post what happened. So, i got the Ergostand LX-928, and its making progress. My laptop use to shut down when i play game for an hour, but with this stand, it shuts down within 3 hours. But no problem, i figured out why its shutting down, i use w put the laptop above a pillow, that is filled with dusts, so the dust entered the laptop, and it entered the cooling place ( don't know what its name ) and it stop turning right. So, nothing then (مجفف للشعر) can do :p

Man do you know what you are doing?? You're running your laptop against a brick wall! If it shuts down in 1 hour, 3 hours, or a month, it does not matter, it's overheating! Honestly, how much do you expect this laptop to last?? Second thing, do NOT, I repeat, DO NOT, use a hair dryer on anything that is even remotely related to electronics. Heat = static buildup = dead electronics. Use cold air, as in, air with absolutely no heat, not even recommended from a hair drier, even if cold air. Use a leaf blower or something of the like if you don't want to open the laptop up.

Believe me, a laptop building up dust is not as big an issue as you think. Tiny fan, positioned on the bottom, builds up fine dust, not the carpet-like dust you see in PCs. The issue is resting it on surfaces that choke the laptop.

First download CoreTemp / Realtemp (latest version, be sure it is 32-bit) and run each, see which you prefer. CoreTemp gives each core usage in %, while RealTemp has a timer that records for how much it has been monitoring temps. Best combo to me is to manually set a timer and use CoreTemp, then you can be sure that EACH core is running at 100%.

Download Prime95 (latest version, be sure it is 32-bit) and run it, it will display options for a torture test, there are 3 options (1st and 3rd options are called small fft and blend), select the 2nd option.

Record max temperatures (they will be displayed by the software) and report them here, along with duration of the torture test.

Once temperatures pips to 90C, stop the test! Make sure you get familiar with starting and stopping the torture test so you know what to do once you are faced with 90C temps. Once you stop the test, it will be on the side in the taskbar, colored red, if you want to restart torture test, double click and choose torture test. It will turn green. Also, keep checking if any of the software's logs reports a hardware failure.

Be careful man.

My laptop start to turn off by it self again, and this time it isn't overheating, its really cold, it shuts down when i play a game :S
do you have the latest driver update of ati 5470 if no try update then post what happens.
Your graphics card is corrupted , because it will use intel IGPU when you'r not gaming and use the dedicated GPU (Which is corrupted) when gaming , so I think that's your problem.
Try turning off the dedicated GPU from software or from the BIOS.
or updating the drivers might also work. did you do anything different from the last time you fixed your problem?
