Not sure on the usb problem ,i assume you install the usb device drivers for it !

The first thing you should do, if you haven't already, is find out the make and model of the motherboard and get the drivers for it.

The word "conflict" in PCI device error messages refers to incorrectly assigned PCI resources. The problem usually lies with the system assigning a single Interrupt Request (IRQ) line or I/O address space to two different devices at the same time. Although current PCI specifications require that drivers be able to handle "shared" IRQs, it doesn't always work out that way.


If that's what is happening on your system, here are three things you can do to try to eliminate the conflict(s):

1. If the devices are actual PCI cards (that is, not built into the motherboard) you can put one of the devices into a different physical PCI slot; doing so can force the system to reallocate IRQ and I/O resources at the next boot-up. If your video card is an AGP card, the possibility of an IRQ conflict still exists, because the AGP slot is usually hard-wired to share an IRQ line with one of the PCI slots (exactly which slot is shared depends on the model of motherboard).

2. If your BIOS' setup program has a setting to enable/disable Plug-N-Play (PNP), sometimes toggling to the alternate setting will clear things up.

3. In Device Manager, you can manually configure resources for each device, although this method can take a bit of "trial and error" to find a non-conflicting configuration.
