python
import psutil

def get_running_processes():
processes = []
for proc in psutil.process_iter(['pid', 'name']):
processes.append((proc.info['pid'], proc.info['name']))
return processes

if __name__ == '__main__':
running_processes = get_running_processes()
print("Running Processes:")
for pid, name in running_processes:
print(f"PID: {pid}, Name: {name}")

This code uses the `psutil` library, which provides an interface to retrieve information about running processes. When executed, it will display the PID (Process ID) and name of each running process on the computer. However, it’s important to note that this code alone cannot solve the issue of a sudden slowdown; it is merely a basic tool that can be used as a starting point for diagnosis.

Network and Browser-related Problems

If you’re experiencing network and browser-related problems on your computer, such as slow browsing speed or frequent freezes, there are a few potential causes and fixes to consider.
