GPU hitting 97c from gaming

I haven't played much on my laptop in a while and i got Sniper Ghost warrior couple days ago and started playing that. As soon as i start i can see the temps sky rocket up from 50c idle to 70c within minutes. After 10 minutes or so it's already at 90 and still steadily going up. After i installed windows 7 my 7805u has been acting weird. Everyone now and again it would freeze up and i get a blue screen saying windows has crashed and dumping physical memory. Also i have not been able to flash and of the bio's cause i keep getting some weird error. Not that i did up change any of the graphics card settings and everything on the game was set the the lowest option possible.

 

Have you tried to reinstall windows? Or repair windows with the installation disk?

 

I dont know if its because i have the upgrade version of windows 7 but when i put the disk in, the only option i have is to install, which im not entirely sure what i does. Also is formatting the only option because i have a lot of stuff that would need to backed up and it's quite annoying.

 

Have you looked to see if the fans are running/spinning? Have you used compressed air to clean out the dust from the laptop?

 

Haven't had this laptop for long but i didn't ever clean it now that you mention it, but i doubt that is the issue. Ill probably get me some compressed air tomorrow to see.

 

youd be surprised at how much of a difference cleaning out a little dust can make.

 

How does one go about getting dust out?
Buying compressed air and shooting it into the side vents?

 

yeah pretty much. Just make sure your notebook is off when doing it though.

Blasting air into operational fans will make them spin much faster than they are supposed to and therefore be deterimental to their bearings.

 

What drivers are you running? Windows 7 doesn't necessarily install the correct video drivers. You should have downloaded from Gateway site or NVidia site.

 

Use compressed air to clean out the vents...do it outside or something so the dust doesn't fly around everywhere.

If you're savvy enough, go get a screwdriver, open the CPU panel on the bottom off and take out the dust bunnies that's accumulated on the heatsink.

Report back with results.

 

Heres a tutorial on how to repair windows with an installation disk: System Recovery Options - Windows 7 Forums

Basically pop in the disk, boot from disk, select your language, then click repair windows.

 

I get my drivers and updates from the NVidia sites so i dont really thing that is the problem.

Thanks man, ill give that a try tomorrow after i borrow a HDD from my friend, will it format my computer or just fix?

 

I used to think the same thing, and I was hitting 96-97 too (and getting the video driver crash) before I decided to take apart my laptop all the way to the motherboard and clean everything out. I also applied some thermal paste to my GPU and GPU memory units (there's 4 of them and they have no paste on them by default). My temps went from 97 and crashing to 70 degrees under MAX load on the same clock settings. One of the major things about cleaning out manually instead of using compressed air is that this laptop is designed in a way where the vent for the GPU can get easily clogged with dust, and there is no way compressed air can get it out. I literally took out a half inch thick chunk of dirt from the vent area which was blocking the passage of air at least 70%. It's a bit of a long process to take apart your laptop completely but once you do it, you get the experience and you can do it again more easily and faster. Here's the guide on how to do it http://forum.notebookreview.com/gat...embly-guide-covers-all-17in-fx-notebooks.html
good luck

 

I suffered from the same dreaded 90C+ temperatures. 2-3 minutes of using a can of air to remove the really tiny film of dust in my vents dropped my temperatures by 25C. I now can game at 75C-80C for hours.
