What error is indicated by post error code 300-399?

Video card error
Keyboard error
Mouse error
USB error

The correct answer is: Keyboard error

The error indicated by post error code 300-399 is a Keyboard error. This means that there is an issue with the keyboard, such as a stuck key or a faulty connection. It is not a Video card error, Mouse error, or USB error, as those would have different post error codes. It is important to pay attention to the post error code to determine the specific issue and address it accordingly.
