If Something Goes Wrong
Resolving a hardware conflict

From the Windows

® 

Help menu, click the Contents tab and 

select Troubleshooting.

Click If you have a hardware conflict and follow the steps.

If there is still a problem, the operating system should display a 
message that explains what the conflict is. For further assistance, 
contact your system administrator. 

The smooth operation of the system depends on the interaction of 
all devices, programs and features. 

The recommended procedure for getting multiple devices to work 
together is to add and configure one device at a time. After you 
add each device, test it to make sure it and all previously connected 
devices work.

The device most recently connected to the system is the one most 
likely to be causing a hardware conflict.

Computer components need resources to accomplish a task. A 
device, such as a CD-ROM drive or a modem, needs a channel to 
the computer’s Central Processing Unit (CPU). It also needs a 
direct channel to the computer’s memory to store information as it 
works. These channels of communication are commonly referred 
to as system resources.

The channel to the CPU is called an Interrupt Request (IRQ) 
because it interrupts what the processor is doing and requests 
some of the processor’s time. If two or more devices use the same 
IRQ, the processor doesn’t know which device is asking for 
attention. This causes a hardware conflict.
