Overheated GPU causes power off

Hello, my laptop has an nvidia 8800 GTS 512MB and it does a hard shutdown very frequently whenever I play any games. This includes older games like Neverwinter Nights which I play on my linux hard drive and also on Fallout 3 which I play on my Vista hard drive.

Is this a problem experienced by other people and is there a solution? Thanks.

Also, I downloaded ntune and see there is an area to manually control the gpu fans, but the buttons for the fan control are all gray....I can't click anything on that section. Does that mean my GPU fan is dead?

Is there a better program or how do I make it so I can manually control my GPU fan speed with the nvidia control panel?

 

Yes most nvidia 8 series have this problem. My gpu turns the screen black for a few seeconds to cool of while playing cod4. Rainbow/purple sparks are usualy a sign of overheating. Try a laptopcooler, my black screen freezes are gone since I bought one (a logitech cooler which is total junk, so if you go for a decent cooler like the cryo lx or zalman coolers, you will definitly have a temperature decrease).

 

Try monitoring temps with HWMonitor or Everest, clean the vents...

Did this happen to you ever before. If not, then your vent is full of dust.

 

I just checked my GPU and CPU fans by removing the covers and powering on the machine. Both fans are running fine and there is no dust.

I would like to know if there is a tool I can use to set my GPU fan to full time maximum RPMs. The nvidia control panel that I downloaded from their website has all the fan controls grayed out.

 

that's exactly what happened to me after I upgraded my graphic card.
the gpu was overheating (more than 85C)
The problem was mainly that the contact between the gpu core and the heatsink wasn't good enough I had to add some copper between them
I also linked the cooling fan inside the laptop to the gpu with copper as it was linked to the cpu
(transfer all the heat from the gpu to the cpu to make the fan run faster when the gpu overheat)

My advice would be to check first with gpu-Z where the problem come from
memory, gpu core?
add some copper sheet on the memory and the core if needed
(choose copper and some good thermal compound to any thermal pad)
buy a small desktop fan (cheaper and better than any laptop cooler but noisier)
underclock/undervolt your card
I guess your laptop has a cooling fan inside dedicated to the gpu
check the drivers too

 

when you put copper on the memmory on the gpu itself do you add thermal paste on top and also on the memory?

 

85C shouldnt cause overheat, and the 8800gts was a fairly good card if i recall, not like the 84-8600m, hows the airflow with the laptop. Do you have it raised or anything like that, have you tried playing a game with the bottom off?

 

You can undervolt the CPU to reduce heat on GPU by a few degrees... look for The Undervolting Guide in the forum..... also get a notebook cooler...

 

AFAIK there is no such software unless you have Dell.

Check the temps.

 

Unless you snip the RPM cable dont do it!

 

lol........

 

That's a well known problem with many HP laptops.
