Answer:
Processor
, Video-card , Memory
Explanation:
If you turn on your desktop computer and the monitor remains blank, the problem might either be as a result of Processor not working, Video card bad and memory not sitting well.
if the problem is associated with processor, do the following:
- Check if the power LED light on the motherboard is on or off.
- If the LED light is off, check for motherboard or power supply issues.
- If the LED light is on, check if the processor fan spins when the system is powered on.
Another major cause could be that the Video card is bad first thing to do is Update the drivers, then reseat the Videocard or probably change it.
Lastly memory module is loose, the computer might not display an image. In other words, your computer starts but the screen is black.
Now, you can try resetting the memory modules to fix the "PC turns on but no display" issue. Remove memory module from the memory slot, and then put it back into the slot to get a better connection so that the computer can recognise the memory.
Computer checkup/maintenance. You forgot to mention windows updates, it is critical to perform that action as well cause of the recent ransomeware malware that is going around lately and Microsoft and other OS vendors yes even Apple have released patches to prevent it spreading even further.
Answer:
import sys
import turtle
import random
def n_pointed_star(total_points):
if total_points <= 4:
raise ValueError('Not enough total_points')
area = 150
for coprime in range(total_points//2, 1, -1):
if greatest_common_divisor(total_points, coprime) == 1:
start = turtle.position()
for _ in range(total_points):
turtle.forward(area)
turtle.left(360.0 / total_points * coprime)
turtle.setposition(start)
return
def greatest_common_divisor(a, b):
while b != 0:
a, b = b, a % b
return a
turtle.reset()
n_pointed_star(5)
Explanation:
- Inside the n_pointed_star function, check whether the total no. of points are less than or equal to 4 and then throw an exception.
- Loop through the total_points variable and check whether the result from greatest_common_divisor is equal to 1 or not and then set the starting position of turtle and move it.
- Create the greatest_common_divisor which takes two parameters a and b to find the GCD.
- Finally reset the turtle and call the n_pointed_star function.
