David...
Has disabling "streaming sound" stopped the freeze? I'd be interested to
know (and could your repeat the sound card you have). Also, this might be
hard to do (usually you have to have someone watching for you), but can you
determine if your hard drive is "active" when the freeze happens? This is
easiest to detect by seeing the hard drive activity light come on...or blink
quickly, just as the freeze occurs.
Here's a new area (new to me) that can cause freezing. Side Band Addressing
(SBA).....and Fast Writes (FW).....are not compatible on some video
card/mobo combinations. These are complicated issues and probably not
within the scope of a newsgroup post. But here's a "***" on each:
FW: Not compatible on AMD platforms (works on Intel boards) and can cause
all kinds of weird behavior. Disable it in the mobo BIOS AND in the video
card vga-BIOS.
SBA: There's no mobo BIOS setting for this. It is found in the video
card's vga-BIOS only. Some GF4 cards have it enabled by default. Most have
it disabled by default. It robs you of FPS and does nothing that it was
intended to do. It can cause screen freezes and graphic anomalies as well.
You made a comment above about using a video card tweak utility to set the
AGP port. My experience has been that using anything other than a direct
BIOS entry for this is unreliable. The mobo BIOS doesn't do well when some
kind of TSR tries to override it. Why not add some insurance and set the
AGP directly in your mobo BIOS at boot up? Try setting it to 2x (128 for
the aperture) and see if that stops the screen freeze. If it does, consider
it a lucky find. The 2x AGP is more stable on many platforms and it only
takes a small hit to the FPS (2 or 3 FPS in N2K2.....not a bad price for
stability). I run only 2x AGP now.....and still get FPS up in the 100's for
N2K2. Maybe you've tried that already, sorry if you have....I haven't seen
all your posts on this screen freeze issue.
What I can gather from your posts I have read, you seem pretty
tech-competent on this stuff.....so my guess is that some little "setting"
is the culprit. Or at least, that's what you are down to since it appears
the freezes are much less frequent now. Keep digging.....you'll find it.
Good luck....
