New to the forum (so HI!), I've had my gateway for 2+ years and have played Wow(world of warcraft) on it the entire time without issues. Now the display dies after about an hour of game play. I wasnt sure what the cause was so I started googling and saw that heating often caused this. After installing speedfan I saw that the gpu was getting up to 107c right before dying. So I'm pretty sure that is the cause BUT I'm not 100% any advice out there?
107 degrees C? Ouch!!! That's scorching. Assuming your CPU is not suffering the same level of overheating, then yes, I'd say that your GPU overheating is the video problem.
First check the fan on your video card, assuming that it has one and isn't a passively cooled unit (meaning one big heatsink without a fan). If the fan is working fine and spinning, check the little air ducts around the fan. If they are filled with dust the card will overheat due to lack of air flow.
If those are clean and the fans are working, it might be that the thermal paste (or pad) has dried up. If this is the case you will need to clean off the old paste from the GPU and heatsink, then apply a new (preferably better) paste to it.
Bring down your temperatures ASAP. Let me put it this way. Your GPU is running seven degrees over the boiling point of water. That is not good for it. If you don't want to kill your system, fix the overheating before you do permanent damage and need a new GPU.
The GPU has a fan, it's a little dusty but I dont see it being the problem. The fan also has a guard on it, am I supposed to remove this or what? It doesnt look like its made to come off.
EDIT the fan has screws on the bottom side lol...fail me.
If you think the heatsink is not too dusty to cause the 107 degrees, then you have to consider the overall airflow. But in any case, clean the GPU heatsink anyway. You can use an ordinary vacuum cleaner to clean the heat sink. In fact I prefer this because the dust & debris will be sucked into the vacuum cleaner bag instead of blown away elsewhere...
Just for tests sake, I cleaned it up and put it back in and everything was fine. I'm thinking I'll still redo the thermal paste but as of now (after about 2 hours of gaming) the peak was 71c, prior to the cleaning 71c was the mean.
Much better. Yeah, that looks like either a crappy thermal pad or some really bad paste on the heatsink. If that is paste, then the company really put it on heavy. Just remember too much paste can be worse than too little. Thermal paste turns into an insulator if applied too thickly. I bet with a good layer of AS5 your temps will drop even lower. In any case you're back into the safety zone.
