Most likely you have conflict of IRQs, try to install the network card in another port. Or try to switch places for your video card and the network adapter.
To avoid conflicts with preassigned devices, you could typically assign IRQs 10 and 11 to a Network Interface Card (NIC). These IRQs are often available for use in modern systems, as many standard devices are assigned IRQs 1 through 9 or 12 through 15. However, it's always best to check the specific hardware configuration and the system's IRQ routing table to ensure there are no conflicts.

(I assume that you meant this to be about an x86 PC) 16 IRQs without an APIC (old computers.) Up to 255 with one. Normally a lot less, though.
IRQs 3 is reserved for the COM1 port.

Interrupt Requests are method for handling requests from components such as Keyboard, Mouse, Clock etc & get attention of Processor.Each specific components is assigned IRQ number.
9 and 11 9 and 11 Try IRQ9 and IRQ10. IRQ 9, 10, and 11 have no default assignment (Chap 6 Network+ Guide to Networks)Read more: Which_two_irq's_can_you_assign_to_a_NIC_without_causing_a_conflict_with_preassigned_devices
IRQ 14 is primarily used by the Advanced Technology Attachment (ATA) interface, specifically for the primary IDE (Integrated Drive Electronics) hard drive. It allows the operating system to communicate with hard drives connected via the IDE interface, managing data transfer and device control. In modern systems, however, IRQs are often managed by the operating system, and the traditional usage of IRQs has diminished with the adoption of technologies like SATA and USB.
Windows 2000 and on used IRQ sharing because the OS would allow more and more hardware. There is a set number of IRQs (15 or 16).
None. A microprocessor is a control and datapath strung together with a bag of bits to manage IRQs communicating over some kind of system bus.The PowerPC 405 is a microprocessor.
