Processor: Intel Core 17 Q820 @ 1.73GHz
Graphics: ATI Mobility Radeon HD 4650
I've got this nearly two years old Studio 1747. The computer started to shut down every now and then when playing games during winter/fall this year. The first thought was some kind of virus or such, but after a completely reinstalling the OS and everything else, the problem's still there. I've now checked the CPU-temperatures, which seems to be around 65-70 celcius as we speak, having nothing but Google Chrome browser running. As soon as I start a fullscreen game they jump to 85-100 celcius. I can't play, for instance, Monkey Island for more than 20 minutes before having to shut it down to let it cool off, or it'll automatically shut down in a couple of minutes. I'm not sure about the graphic cards temperature.
I usually have the computer standing on a couple of pencils to improve the airflow, but it seems to make no big difference.
Any clues on how to solve this?
First thing to do is verify that the fan is operating correctly - F12 at powerup. BOot to the Dell diagnostics and run the full system test.
Check the heatsink assembly for signs of dust buildup - and clean accordingly. Just a little coating of dust will prevent the heatsink from doing its job.
I did boot the Dell diagnostics, passed the first 30 tests, chose to run the remaining 30 minutes, but the computer shut down after only a couple of minutes into that sequence, most likely due to overheating.
How do I check the heatsink assembly? I guess it'd be a good place to start. Guess I can google it, so I'll try that, but still!
Thanks a lot for your reply and I hope you'll bare with me!
Thanks a lot for your help. I tried this today, but quit at step 12. Didn't feel confident enough when it got to the point where I had to remove all the small cables and get them out through the routing guides and cable routing slot. Oh well.
Thanks anyways for your help! I guess I've gotta live with this, or hand it in and get it fixed for maybe a hundred bucks!
Instead of recall or redesign, Dell have continued since c2007 to sell this laptop in this defective heatsink configuration to new customers fully aware of this being a manufacturing defect through not fit for purpose design.
And if you attempt to escalate the matter despite that widespread evidence, you are forced to navigate through the plethura of highly problematic overseas call centres in the Philipines and India instead of local in country escalation, and you will receive complete denial, generally defensive and ill informed rhetoric and very little else.
Michael Dell himself should really take note that this level of sales and aftersales service really does make an international corporation with all the resources otherwise to do far better, a hopeless laughing stock.
Even the maintenance engineers that examine the heat exchanger have had to admit that for the normal operating environment into which the Dell product is sold the thermal exchange blades are designed to be much too close together and with insufficient ingress egress apertures and become easily and unacceptably clogged with dust so as to cause overheating within an operating envelope that can never be user servicable.
I worked in UK government for nearly 20 years, served in a technical IT division as head of CAD training for UK govt. in the days when Dell really was a very worthwhile IT manufacturer and supplier in the government and private sector - somehow they have really lost it which is a shame.

Install it and tell it to disable the Turbo of your i7 CPU. this should prevent your laptop from overheating.
the webpage tells you where to download it, how to install it and how to set it and everything
I had same problem with my computer shutting down. It would crash whenever I would run the CPU stress test. I figured if the problem was a dust build up on the fan and heat sink then....remove the dust. I used an air compressor to clear the vent and fan of dust. I then reran the CPU stress test and the computer passed. Just be careful not to use too high a pressure air if you use a compressor to clear the dust out of your laptop.
Mine would shut down randomly. Last night while trying to finish a 5 minute HD video it shut off on me 3 times in a row. After reading this I blew air into the fan from the bottom and a little dust flew out. When I blew air from the back a huge cloud of dust blew out. I just finished the video that I could not last night. Also when I think back it would always shut off on me when it was on my lap. I guess my leg must have been blocking the fan. Thanks for everyone's help.
