laptop overheating and crashing while gaming.

post #1 of 6
Thread Starter 
Hi, My notebook is a Lenovo Y560 with an i7 720QM and ATI 5730. 4GB RAM, 640GB HDD, etc etc.

The first game I played was Half Life 2 and Episod 1 and 2. My notebook used to get reeeealy hot.... and eventually hang, the sound would get stuck and repeat, screen would go blank, I had to reboot.

I then bought an average quality cooling pad with a big central fan and that helped, I placed the fan under the left side of the laptop which got hot, and it stopped crashing but it was still quite hot to the touch near the vents. This was 2 months ago.

Now I recently bought Counter Strike Source on steam, and the crashes are back, only this time the cooler doesnt help. I get temps as high as 90C++, this is when my laptop crashes, and twice I think its gone high enough to reach the motherboard kill switch limit, which im guessing is 100C or 105C, where my laptop just turned off.

What I did realise is if I alt+tab I can immediately notice a decrease in temps... so what I now end up doing is, alt+tab whenever I die and am waiting for the round to get over, and watch temps drop down till 70, then go back ingame, play, and keep alt+tabbing and watch temps go down a few degrees. This has greatly decreased the crashes, but it still happens when I dont alt+tab and continue ingame for a long time, for example 30minutes+, yea 30 minutes ++ and I'm at 80C+..
My ambient room temp is about 30C+, summers in India and its hot, and my Idle temps are around 60C.

My VGA card is fine, doesnt go past 70C, its my CPU thats heating up. When Im rebooting I can feel the heat on my power button while im pressing it for the 5 seconds.

I just flashed to the new Bios and installed a new Intel Chipset driver from lenovo's site, but that doesnt help much either.

I've considered disassembling the notebook, and reapply TIM on the CPU and GPU, but I want to keep that as a last resort, this notebook is hardly a few months old.
Need some help please.

Thanks

Well, I'd run Prime95 or other stress test with MSI afterburner to see if it crashes then. I'm thinking that the cooling system can't handle the load of both proc and gpu being stressed.
My first thought was reapply TIM (it's most likely thermal pads though) and clean out the HSF on the inside, but that's your last resort.
Any chance you can get it sent back for repair then? Or you could try to downclock it using a software OC utility.
I think the HSF is at fault here...

I shall run some stress tests and test it out further, meanwhile posted on Lenovo forums too to see if the people at Lenovo would consider this a fixable problem so I can send the notebook to them.

Downloading Prim95 now, I assumed the cooling was at fault, but the crashes seem out of place, shouldn't it normally just reach the kill switch and turn off? rather than crash?
I would like to know any possible reasons for it crashing, I've experienced artifacts on screen if the GPU is overheating, but never this.

The bolded are your options.

Those seem like your only options at this point. See if you can undervolt it yet still keep a stable stock speed? Or lower the clockspeed if you have to.

Update:

The BIOS update, i.e to BIOS71 from BIOS30 seems to have fixed the problem for now.

These are my temps under load, after about an hour of gaming:
12.jpg

Ambient room temps were 24C - 25C... no crashes, even though apparently it did go up to the 90's... but averaged at aroun 85, I alt+tabbed multiple times to take screen shots, and that was the highest temps I got, most were around 83C to 85C.

Im going to run prime95 tonight and see if there are any crashes, if the crashes are fixed, Ive got another question..

How safe is the processor or what longterm health risks are there to the processor running at ~85C + for an hour++?? Or is that normal for these processors?

Edit: Sorry for double post. redface.gif

Update2:

Ran prime 95... WOW it ran hot! but thankfully no crashes, so I "seem" to have fixed that with the BIOS update.

Now all I have to worry about is the overheating. I stopped after 4 minutes, it was getting a liiiitle too hot devil.gif!!!
