Hello jawad2010;
Can you use the zte Wimax Bcm100 with the Ethernet NIC instead of USB?

am suspecting it could be hardware issue, can you confirm if you are running windows 7 on appropriate specs ?

Hardware Interrupts are caused by hardware devices which are plugged in. Here is what happens.

When you plug in any hardware, Mother board uses Interrupt controller (IRC)to multiplex the interrupts to the processor, which means these hardware devices cannot directly talk to the processor. This IRC will assign a specific interrupt line ( for 32bit there are 32interrupt lines ) , so one of the line would service the request.

Later Operating system has its own mechanism to service interrupts whch it does using IRQL and DPC . And all these happens on "specific bus"

device --> bus --> IRC --> IRQL --> driver enumeration.

After whicih the driver enumeration happens and the IRP would be processed / you can perform i/o operations



So when you say you are seeing interrupts, you have to distinguish between software and hardware interrupts

One way is to perform your BIOS update

other way is to remove all the external devices which you plugged in

3rd you could disable even network adapter , such as wireless and in built and test

4th you can use kernrate utility to diagonise and paste the kernrate for analysis here
