How To Troubleshoot Vertical Lines on the PC Screen

By -

There are a number of possible factors computer screens show vertical lines. These factors ranges from: the screen settings, excessive heat causing damage to the GPU, the RAM is faulty where the GPU gets its VRAM from, or the functioning of the screen itself. One of these underlying issues might be causing vertical lines to display on your screen. Sometimes, to rectify this problem can be simple and easy, other times can require technical troubleshooting.



TROUBLESHOOTING GUIDE


1. Update the graphics driver
Right click Start button and select Device Manager. Check for graphics or video card drivers with a yellow error sign. If it has a yellow sign on it, double click on it and open Properties. Click on Update Driver under the Drivers tab. After updating, restart your PC. Updated drivers are crucial for maximum performance and stability. If the vertical lines still show after driver update, move to the second option.


2. Switch off Computer and disconnect all peripherals.
If you are using a laptop, take out the battery and remove the charger. After that, press and hold down the power button for 15 to 30 seconds to release all the residual power left in the system. PC motherboards have a 3.0 volt battery that powers real time clock settings even when powered off and disconnected from the PSU, firmware settings stored in volatile RAM even though latest motherboards store all firmware settings in Flash Memory (Non-volatile RAM) and also provide power to the power control circuitry. Connect everything back and turn the system on to check and see if the problem is fixed.

If you're using a desktop, disconnect the monitor from the computer and wait to see if "No Signal" message displays. If the vertical lines shows as the message displays, then the monitor is the underlying cause of the problem. You can reset the monitor to Factory Settings mode by pressing the menu button on the screen and navigate through the setting using the other buttons. If the lines still shows

3. Check for vertical lines at boot.
If you see the lines right at boot even before the OS loads, it may be either the video cable or the video card or possibly the screen itself. If the lines display only when Windows load to Desktop environment, then the problem resides in Windows setting. You may Right-click on the Desktop and select Screen Resolution. Click on Advanced Settings, select Monitor and then reduce the refresh rate and check to see if the lines are gone.

For further troubleshooting methods, try using "System Restore" in Control Panel to restore the system to an earlier state. After going through all methods and problem still persist, the screen may possibly be damaged and can't be fixed.

How Hackers Grab Encrypted Passwords and Crack Them

By -

One may have asked, "How do hackers take my password, if the website owner can't?" The answer is simple. When a website stores your login password for the site, it is run through a cryptographic hash function before it enters the database.  So how do hackers get these passwords?  When a website is breached and has their database stolen, the password hashes will be in there. A hacker will analyze the hashes, and see which   hash type   they are, and then bruteforce them. Bruteforcing is when you systematically cycle through each letter in a letterset until it matches a password. A letter set can be all lower-case, upper-case, symbols or anything the hacker wants. So the hacker bruteforces until they find a hash that matches yours, resulting in "guessing" your password. I dedicate this tutorial for anyone who wants to understand password attack vectors and those training for careers in cyber security.  L ets run through what it takes to hack a password using the c...

As the hacker is among the most skilled information technology disciplines, it requires a wide knowledge of technologies and techniques. To truly be a proficient hacker, one must master many skills. Don't be discouraged if you don't have all the skills I list here, but rather use this list as a starting ground for what you need to study in the field of cyber security and master in the near future. This is an overview list of required skills to enter the pantheon of this elite IT profession. I've broken the skills into three categories to help you go from one rung to the other more easily—fundamental, intermediate, and intangible skills. NB: For Educational Purpose Only The Fundamental Skills These are the basics that every beginner should know. Once you have a good grasp on everything in this section, you can move into the intermediary level. 1 Basic Computer Skills It probably goes without saying that to become a good hacker you need some basic computer s...

How to Use Maltego for Network Reconnaissance

By -
Image
Before you attempt to exploit any target on a network you've been authorized when pentesting, it is wise to do proper reconnaissance. Without doing reconnaissance, you will likely be wasting your time. In this tutorial, we will be using an active tool called   Maltego , developed by   Paterva , that can do many of these tasks with one simple scan. There is a community edition built into our Kali Linux that allows us 12 scans without purchasing Maltego. It is capable of a significant amount of information gathering about a prospective target in a single sweep of the domain. Using Maltego in Kali to Recon a Target Network Maltego is capable of gathering information about either a network or an individual; here we will focus on the network and leave individual information gathering for another time. We will be looking at gathering info on all the subdomains, the IP address range, the WHOIS info, all of the email addresses, and the relationship between the target domain and others...
