Answer:
The answer is "option a".
Explanation:
To resolve the automatic reboot problem we must change the CPU cooling fan because if we don't change a computer fan so, it will be heated and damage other components. This cooling fan used inside the CPU. It expels warm air from inside and moves air across the particular component. and other options are not correct that can be described as:
- In option b, power supply is used to turn on the computer. It is not used to solve the reboot problem.
 - In option c,  Motherboard is to serve as the base upon which a computer's components are built.  
 - In option d, It is primarily used to store the data.  
 
 
        
             
        
        
        
Answer:
1. DLL Files. 
2. System software repair. 
3. Software configuration. 
4. Human-computer interaction. 
5. A graphical user interface (GUI). 
Explanation:
1. DLL Files can become lost or damaged on a computer and prevent it from working correctly. These are important registry files used by various system softwares to perform specific tasks. 
2. System software repair is a type of software you can run to help fix computer problems. Some examples are disk defragmenter, regedit, etc. 
3. Software configuration means the process of setting up an application and selecting specific options. This is usually done in the settings section of a software application or program.

Answer:
#include <stdio.h>
void interchangeCase(char phrase[],char c){
   for(int i=0;phrase[i]!='\0';i++){
       if(phrase[i]==c){
           if(phrase[i]>='A' && phrase[i]<='Z')
               phrase[i]+=32;
           else
               phrase[i]-=32;      
       }
   }
}
int main(){
   char c1[]="Eevee";
   interchangeCase(c1,'e');
   printf("%s\n",c1);
   char c2[]="Eevee";
   interchangeCase(c2,'E');
   printf("%s\n",c2);    
}
Explanation:
- Create a function called interchangeCase that takes the phrase and c as parameters.
 - Run a for loop that runs until the end of phrase and check whether the selected character is found or not using an if statement.
 - If the character is upper-case alphabet, change it to lower-case alphabet and otherwise do the vice versa.
 - Inside the main function, test the program and display the results.
 
 
        
             
        
        
        
First, check that your drivers are up to date. The lag could be caused by outdated drivers that are essential in running your system smoothly. New updates will fix bugs, known errors and will make programs work better and faster. Next, run your anti-virus software to check if malware, spyware, and adware that could be putting your computer at risk by installing hidden files, downloading stuff from the internet and uploading sensitive information from your computer. These unauthorized activities could be eating up your RAM in the background without you knowing and thus making your computer run slowly.
