Sometimes ports go bad or become faulty. A damaged driver or out of date data can cause port problems. Also, PC can develop port problems when new hardware or software clash with each other. Faulty ports are simple to substitute, particularly if they are on a PCI card. If one of your devices ends working, you must try to troubleshoot PC to decide what precisely is causing the problem.

History

1. Many modern PCs have some ports placed in back or front of PC. The ports are intended to attach peripheral devices, like printers, keyboards and modems. Ports permit data to move between PC and external devices.

General errors like attaching a device into wrong port can show as if port is not working. Although some ports look equal, you must ensure that you attach cords into right ports. Generally, icons are marked on PCs and cords to be utilized as guides to help you attach external devices to PC.

Significance

2. Before you start troubleshooting, you must turn off PC. Ensure to test that cords are attached to right ports and firmly tighten them. Then, restart PC. Windows operating system will notice any drivers that did not load appropriately. If port problem is not solved, you must use Windows built-in troubleshooter to help you recognize the problem or rule out hardware failure.

Identification

3. Generally, ports that are not organized appropriately nor have an IRQ clash may cause problems with a device attached to a USB port. The IRQ is a type of bus signal that permits hardware and software on PC to interrupt, or place whatever CPU is doing on hold and perform the request.

Function

4. If you have decided that port is faulty, you can buy a new PCI card to change faulty port. To install PCI card, you want to open PC case and change faulty port. Read the user manual and follow the instructions. You want to update drivers on PC and install drivers for new PCI card.

Benefits

5. The better way to prevent port problems and system clashes is to utilize USB devices. But if you want to change a faulty port, it's helpful because changing PCI card is cheaper than changing whole PC system.
