Computer mysteriously freezes...

Since I upgraded to athlon t-bird 1.4ghz using
ASUSTeK Computer INC. VIA A7V266 motherboard
NVIDIA GeForce2 GTS/GeForce2 Pro
my OGL program freezes up after a while at some specific areas in the code, such as:
Drawing a bunch of billboarded particles (No light)
Drawing a bunch of triangle strips lightened by a single GL_LIGHT.

Strangely enough, adding some GL_LIGHTS to Quake2 source code produces the same mysterious freeze ups aswell.

Most games on my computer (including quake3) freezes up like this after a couple of hours, but my code freezes in 30 seconds just drawing some alphablended particles.

Anyone experienced similar problems with latest hardware or hardware drivers using OGL?

Additional information:

Im using MSVC 6.0 for developement.

I don’t have experience like this but try to check you driver

or format c:

Yes, the 23.11 drivers are CRAP.

They caused all sorts of lockups… use another driver version!

Also, if you haven’t already, ensure you have the latest 4-in-1 (AGPgart) drivers installed.

I agree with Goatboi - it sounds a lot like a common problem with the VIA chipset - make sure you have the latest VIA drivers installed before you look at other areas.

I have the same motherboard with the 1900+ XP with GF3 and have no problems with the 23.11 DetonatorXP drivers.

I did have similar problems with hangs until I installed the various ASUS drivers from the CDROM that came with the motherboard after bringing up the system with the new hardware.

dorbie, don’t know what else it could be, besides the 23.11 drivers.

Since now, I haven’t had a lockup/freeze for over 2 days, before, with the 23.11 drivers, my opengl programs would lockup win2k solid, not even ctrl-alt-del would do anything. It even happened just browsing the net, and the final thing was that it locked up with VC++ loaded when I was about to switch to another window. I also did a search for the 23.11 drivers on usenet, and I did find lots of people have lock ups, and others posted they were good.

This is something hard to track down for Nvidia, since on some people, it locks up/freezes, and others it is OK.

21.85 work good for me now. (As did all drivers before that from 12.00 and on)

I just checked, it’s actually the ASUS A7M266 motherboard I have.

While we’re on this though, just because a new graphics driver makes the difference between running and hanging doesn’t mean that the driver is at fault.

Getting the latest motherboard drivers from the ASUS web site, is probably a good idea.
