Laptop shut down after playing 30 mins of "Big" games

I own a Sager 5793. Now when ever I play big games like crysis and mass effect, my laptop will shut down for sure after around 30 mins. However it never went wrong while playing team fortress, even for 2-3 hours.

I checked the temperature of my cpu, gpu, and harddisk and they seem all fine. (cpu - 4x C, gpu 6x C, harddisk 50 C, all while playing), and my fans seem working fine.

I really don't know what's going wrong. Anyway I can find out wts going on?

 

could u give a better description of ur laptop just shutting down? What exaclty happens? Does it suddenly just turn off or what?

 

yes, just shut down suddenly without warning, after 30 mins of gameplay

 

Are you using a notebook cooler?

Definitely sounds like a thermal problem to me.

 

have you tried changing your drivers for the gpu cos it could be bluescreening as sometime when you get a bluescreen the computer will restart before you see it so its probably worth changing the drivers as this may fix it

 

While the CPU and GPU temperatures look excellent, the HDD temperature is suspect. Technically, an HDD should be able to survive that, but it's not healthy at all.

And just so I know, when you mean shut down, is it a BSOD or just a simple poof, off?

 

It just went off, without any warning or bluescreen ...

I don't think I really need a cooler, since this problem never appears.
Sager's internal fans should be excellent (still working), and my gpu and cpu temp are find ...

yet hdd seems suspect ... anyone knows how to find out if it is the hdd problem

Will this only work if a blue screen come out?

 

It could be a hard drive problem as sager's laptops have problems cooling hard drives... try doing a hard drive upgrade... ur drive might be having faulty sectors .. also update to 186.81 drivers if u got an NVDIA card.......

 

Have you cleaned out the fan and heatsink assembly of the laptop recently?

 

I cleaned like 3-4 months ago (fans + heatsink)

As my cpu and gpu seem to have no problem, cleaning of fans/heatsink might not help that much. Is there anyway to reduce heat of my harddisk (as some one stated above, sager does not have a single cooling device for harddisk, so not sure how to clean it?! or is there any other way?)?

Also any good tool to test the stability of my harddisk? and also the power supply maybe?

 

Cleaning the internals of the laptop makes the difference between a cool laptop and an overheating laptop. 3/4 months is enough for significant dust build-up depending on conditions, so clean it again.
