laptop locking up

By phillip_to ·
Can anyone explain to me why a laptop would lock-up/freeze when performing complex 3d graphical calculations such as those in displaying today's demanding games for example. It is a 3.2 ghz with HT and 1024 mb of 333 ddr ram. In addition it has a Radeon 9600 video card which should be able to handle any and all graphical calculations.
Thank you.

If you have the absolute latest drivers from the manufacturer, try the drivers directly from ATI's website.

If this does not solve the problem, make sure that while you are gaming the computers air vents can all "breathe" by placing the computer on a table, not your lap. This problem sounds very much heat related.

Hope that helps.

Depends on what gaming solution you are talking about...

The 9600-9800's have apparently been affected by the latest developments from the gaming community. From locking up, to shutting down to rebooting the pc. It is a feature for now until the next display driver update gets published. Trust me, I know from experience:

9600se Atlantis - 256mb DDR 8X

Using 2k for my OS, but will apply XP with a fresh install tonight or tomorrow to see if there are any performance differences / improvements (No hang ups)

Also, noticed that a 1024 x 780? will cause less of a lockup than the higher resolution rates.

I'm talking about the latest 3D-demanding games like Command and Conquer Generals (1499X1050X32bit) for example or railroad tycoon 3, they both look great, butthe bastards lock up after 3-8 minutes!

Try downloading sandra 2004 utility from or
Run all the tests and it will give you some good tips on tweaking your system.

- Get all the patches from your computer vendor (there are often bug fixes..)
- Update your BIOS if necessary (see what higher BIOS fixes).
- Try the latest drivers from ATI web sites (using Catalyst drivers)
- If you have a fan on the back of your laptop, make sure it is working.
