These indicators will give you an idea whether it is a driver issue, a conflict with system resource or other devices. You may see an exclamation point, a question mark or a down arrow on the list.

Device Manager errors come with error messages that describe the situation you are having with your computer hardware. Known as hardware error codes, these tell you exactly which part of the computer is having an issue. When you come across Device Manager error codes, you can correct the problem by making changes in the Device Manager section.
