Resource conflicts are often due to PCI cards added to the motherboard.
If you add multiple peripherals, such as graphics cards or sound cards, to your computer system, this can result in resource conflicts. This means that the system cannot meet the demands of all the devices you installed. The BIOS, or basic input/output system, may report a resource conflict during the power-on self-test process. POST is the primary check the computer system completes during the boot sequence.
Symptoms
The computer can manifest a range of symptoms if a resource conflict is present. The system may freeze or hang, especially when a peripheral device is in use. The computer or peripheral devices may make excessive noise during operation. Sound from an audio card may be distorted or unclear. The screen may display random characters. The mouse may move very slowly or not work at all. The printer may print nonsense. Applications may crash or experience random errors. The computer may be unable to format media. Data may incorrectly transfer from various devices.
Static Resource Conflict
If your system BIOS reports a "Static Resource Conflict," it is most likely due to a Plug and Play device. PNP devices are peripherals, such as video or audio cards, which work with the computer system without installing additional software. The user simply plugs the device into the computer's system board. The BIOS may misread the location of the PNP device and assign more than one location to it. Possible solutions for this problem are: rebooting the system, updating or flashing the system BIOS, updating PNP device drivers or removing the PNP device.
Device Manager
If your system detects a resource conflict, you may be able to solve the problem in Windows. Getting to Windows may require that you start the computer in Safe Mode. The Device Manager shows what resources each peripheral device uses. You can disable these devices through the Device Manager, if needed.
Hardware Issues
Hardware incompatibility may cause resource conflicts. Your system may not be able to support all peripheral devices equally. Consult your computer user's manual for device compatibility. Most manufacturers offer online support to ascertain device compatibility, even for legacy systems and hardware. In addition, outdated hardware drivers may be responsible for resource conflicts. Check with your computer manufacturer for driver updates.
Viruses
If the system BIOS detects a resource conflict, but none exists, a computer virus or malware may be responsible. Perform a complete system scan using your preferred anti-virus application. Free applications are available online if you do not currently have any installed. Removing the virus should remedy the conflict.
