all games tearing and shearing

[derah]

My system was working like a dream until cable internet service installed. The end result was having the whole mess formatted. Techs flashed M/B bios as well. I loaded in Half Life(1.013), Unreal (225f), Tomb Raider 4.All setup in 800X600X16 for testing.AGP aperture 256, palette snoop disabled. In D3D , all exhibit very jagged vertical and horizontal lines, hesitations in game play and I can no longer enable volumetric effects in TR4. HL and Unreal show HUGE amounts of horizontal shearing when panning view, redrawing of objects as walk towards and past them and watery planes of floor and walls that always move in front of you. PD5.3 +/- turbo,OGL or D3D, the same as with PD5.4.
I dont know what else to look at.

OK,

Did you have an Ethernet card installed before they came in and setup the cable modem OR did they install the NIC themselves?????

Because I think the NIC and Matrox card are conflicting big time.

So here's what to look for..

1-Make sure there's no IRQ conflicts between the G400 and the Nic

2-Re-seat the G400, basically unplug it from the AGP slot and plug it back in.

3-what type of NIC card did they install, the drivers of that card also could be conflicting with the G400.

Check it out and see what happens.

Subscribing to this provider means that they must provide their own NIC and tech. Won't support you if you do it yourself. So they installed a SOHOware NIC at IRQ 5 in addition to four other devices at IRQ5 as listed:
0 System timer
1 Standard 101/102-Key or Microsoft Natural Keyboard
2 Programmable interrupt controller
3 Linksys Ether16 LAN card (PnP Card)
4 Communications Port (COM1)
5 AOpen FM56-SM Soft PCI Modem
5 AOpen Soft PCI Modem Enumerator
5 Intel 82371AB/EB PCI to USB Universal Host Controller
5 IRQ Holder for PCI Steering
6 Standard Floppy Disk Controller
7 ECP Printer Port (LPT1)
8 System CMOS/real time clock
9 Creative SB16 Emulation
10 Matrox Millennium G400 DualHead Max - English
10 IRQ Holder for PCI Steering
11 Creative SB Live!
11 IRQ Holder for PCI Steering
12 PS/2 Compatible Mouse Port
13 Numeric data processor
14 Primary IDE controller (dual fifo)
14 Intel 82371AB/EB PCI Bus Master IDE Controller
15 Secondary IDE controller (dual fifo)
15 Intel 82371AB/EB PCI Bus Master IDE Controller

There was no obvious conflict with G400. I immediately lost CDAudio and started throwing blue screens. Whole system crashed, wouldn't even boot in safe mode and had to be formatted. Their tech came back and installed a 16bit Linksys NIC in the ISA slot and forced it to IRQ3 after disabling Com 2.I still have the 4 devices on IRQ5. Disabled SB16 emulation to free up IRQ9 and hoped that the PCI to USB Universal Host Controller would have been assigned to IRQ9. No luck. I am now getting ready to remove the AOpen 56K modem. I still can't figure out why
there should be a problem with the G400 at IRQ10 and those devices on IRQ5. The good folks at the Matrox Hardware board are also giving me some help..Lord knows I need it.

I would say now that you have your cable modem is to uninstall all the aopen stuff you have sitting on IRQ 5 for starters.

I uninstalled and removed the AOpen modem and now have only 2 devices at IRQ5: PCI to USB Universal Host Controller and the IRQ Holder for PCI Steering. I uninstalled and reinstalled Half Life, ran with PD5.41 (no turbo) , 800X600X16, D3D and absolutely no change! Shearing , tearing, hesitations, and flashing walls that look like fine black and white mesh.I don't even want to check Unreal and TR4.

derah,
Did the cable modem techs flash your MB? If so , why?
Maybe they turned off busmastering or something.

Actually, this computer is brands new and in order to maintain my warranties, the computer retailer formatted and reinstalled all drivers after the first NIC install disaster. They also flashed the M/B Bios. I'm learning all the time but I alays thought that you left the M/B Bios alone unless you were experiencing serious problems. I suspect that they did so in light of the total system crash. I am going to pull the ethernet card today and then reinstall DX7 and G400 drivers. If that doesnt do it, maybe the new Bios is involved. What do you think?

Oh yes, Quick Desk Information has the bus mastering enabled and Matrox Disgnostic utiltity shows bus mastering woking properly.
Too bad, it would have been an easy fix

When you pulled the Ethernet card out, did you still have the problems?

Yes. Removing the ethernet card had no effect on video problems. The PCI to USB Universal Controller and PCI Steering devices moved from IRQ5 to IRQ3. When I plugged the Lynksys 16bit card back in , it grabbed IRQ3 and they returned to IRQ5 . I took your advice and reseated the G400 in the AGP slot. No good.
The original NIC card was a PCI SOHO Fast Ethernet from NDC. The replacement card is Lynksys 16bit in the ISA slot.Both supplied ny @Home. The only thing I haven't tried yet is obtaining new copies of DX7, PD5.3 and 5.41 and reinstalling .

Derah,

I don't know if this would help you but a couple of months ago I installed a new P3B-F MB (replaced P2B), put everything back in the same as other, had conflicts, couldn't believe it since installing G-400 in july 99, had no problems at all, tried everything I could think of to correct. Down to my last option, I swapped out cards in PCI slots cause I read that SBlive might have problems with IRQ higher than 9, don't know for sure why (I haven't heard of anyone having same problem) but it corrected all my problems. I use P & P which is one mistake but reading your note, you have Sblive on IRQ 11, what mine was to start with, now is on IRQ 3. Some of the problems you are having is what mine was doing. Hope this helps or gives some ideas.

Try to disable the "bus mastering" from G400
Options. This will help stabilize all the D3D-using games (like Unreal, HL, TR4). You'll have to switch it back ON for any OpenGL games, or the same games in OpenGL mode, or they will not run.

Worked for me...

[derah]

I see the exact same problems on OGL as well.
Thanks fo the advice Maybe I am unreasonable, but if I have to disable bus mastering on an AGP card in order to get it to run, then its time to switch cards.
