NIC card clash with usb ports

I have a ahtlon xp 2200, 512mb ddr ram, realtek AC97 built in audio, 32 mb nvidia riva tnt2 card, win xp sp2 n realtek 8139 NIC card, MSI KT4V motherboard.

And my problem is, somehow i think there's a clash between the NIC card and the usb ports. Because whenever the NIC card is on, all the devices connected to the usb ports becomes either unknown devices or i won't start.

Only when i disable the NIC card and restart, will the usb devices becomes usable again.

I tried updating the via 4in1 drivers plus the drivers for the realtek 8139 NIC card but to no avail.

Can anyone please give me some suggestions or pointer on how to remedy this problem?

Thanks in advance.
 
Network Interface Card Card? 😕 Sorry, couldn't resist.

Try the NIC in a different PCI slot.
 
I've tried that but apparently the NIC card won't work in other pci slot.

How can i remedy this problem?
 
Hmm. Bizarre. I'm almost wonder if the NIC card is simply defective, somehow? Which slot did you put it in?

I have an MSI KT4V-L (board rev. 1.0) myself, and have had a $5 Realtek 8139 PCI card in there as well, and didn't have any obvious problems like you describe. I have a USB hub, USB 2.0 WiFi 'G' NIC, USB optical mouse, USB-to-PS/2 converter with a secondary keyboard hooked up, a couple of PSX-to-USB adaptors, and a USB webcam, all hooked up.

When you installed the OS, did you install using ACPI, or the MPS HAL, or the "Standard PC HAL"? With this board, Via/MSI do not provide an "IRQ routing miniport" driver, so you cannot properly share IRQs when using the "Standard PC HAL", you need to be using either the ACPI HAL or the "MPS Uniprocessor HAL". If you open Device Manager, and then select "View by Connections...", and then at the top, expand the "Computer" entry. On mine, it says "MPS Uniprocessor PC", since I disabled the ACPI support in the BIOS before installing the OS. If it says "Standard PC HAL", then you may be in for an OS re-install. (Make sure that APIC is enabled in the BIOS though, before you do that. Be careful, "APIC" is different than "ACPI", don't get confused. I know the terms look almost identical. APIC = good, allows better IRQ sharing, ACPI = possibly problematic, allows Windows' to control power-management.)

On my board though, I do notice some slowdown on my disk and video, when using my USB 2.0 WiFi NIC. My HDs are connected to a Promise Ultra100 TX2 PCI IDE card, which is plugged into slot 4, which gets IRQ 10 assigned at the BIOS bootup screen, which happens to be the same IRQ as the USB 2.0 controller gets.

It's really strange that you say that the NIC didn't work at all in another PCI slot, that really does start to sound like the NIC may simply just be flaky. What about the onboard LAN, does your model have that?
 
Well i've checked in bios n my apic is enabled but in the device manager, it's a standard apci uniprocesser.

N no my KT4V doesn't have an onboard LAN, but just a built in modem. But i've disabled that in the BIOS.

Is there anything else that i can check or do?

Hmm. Well, I'm using the MPS HAL, not the ACPI HAL, but either one should work to allow IRQ sharing, more or less.

At this point? When you installed the NIC, did you let the OS install drivers, or did you install drivers that came with the card in the box, or did you download and install the newest driver's from Realtek's site? (Check here - strongly recommended.)

It's quite strange that the NIC wouldn't be recognized in a particular slot, that doesn't make much sense at all. Actually... I think that at one point, I did have a strange and similar issue, of the card not showing up. Not sure what I did to fix/change that though. Have you ever updated the BIOS on that mobo? If you haven't, you might want to consider that, recent BIOSes have fixed some USB issues during bootup for me.
 
Yeah i already got the latest driver for the NIC.

And i even updated to the latest BIOS.

And i even move the nic to other pci slot, but the same problem persists.

What else can i do?
