Conflicts between computer hardware resources and Solutions

Author: snil Source: Skynet

A typical manifestation of hardware resource conflicts: When you add new hardware or after adding new hardware, the system often crashes and black screens for no reason; when you start, the system enters the Security Mode for no reason; the sound card and mouse cannot work normally or go on strike. When you press and hold the Alt key and double-click my computer icon to view the system properties, an exclamation point appears. The printer and the drive are not working properly. Of course, computer viruses cannot be ruled out, because some of them may have similar symptoms during attacks, so they cannot be generalized.

The main cause of hardware conflicts: When you add new hardware, the new hardware occupies the IRQ interrupt, DMA channel, I/O address, and other computer resources of the original device, there is a resource conflict between the old and new hardware. This will result in the failure of one or more hardware devices to work normally or the instability of the system.

How to check resource conflicts: press the "Alt" key and double-click "my computer/System Properties" with the mouse to view the working status of the hardware device.

In general, if there is a problem with the system, the following three prompts will usually appear:

1. After formatting the hard disk and reinstalling the system, a yellow "?" appears. It indicates a hardware driver error or resource conflict.

2. When you add new hardware to your system, a blue circle "!" appears. . It means that the device can basically be used, but the system considers it problematic and can still work normally.

3. When new hardware is added to the computer system, a severe conflict occurs, and the red "X" is displayed. It means that the device cannot work or does not exist. It will often enable the system to start in "safe mode" or remind you to search for new hardware at startup.

I personally know that the hardware that causes computer hardware resource conflicts is mainly between the PCI1 slot or between the PCI slot and the mouse interface, COM1 and COM2, and between the ISA slot and the LPT1 interport of the printer. The conflict between the video card and the motherboard is good judgment. Generally, the system often starts in "safe mode" or often reminds you to search for new hardware at startup, and often reminds you to search for the latest driver of the video card. For example, an I740 video card conflicts with a VIA693 chip motherboard. There are also conflicts between the card and the PCI sound card, but such conflicts are rare.

Hardware resource conflicts are not difficult to solve, but the preferred solution is to replace the hardware that causes the conflicts. If the conditions are not allowed, you have to use the following methods to solve the problem.
