After reading this article you will be able to solve the problem where corruption occurs on your screen or you see lines across your computer display. This problem might occur due to a Display driver problem, a display hardware error, Display connection cable problem or even a faulty display.

  • OR , to get latest drivers you can use WINDOWS UPDATE
  • To run Windows Update, Go to start menu & in the start menu search box, type Windows Update & press Enter.


  • Refer the above screenshot, you can either press Check for updates on the Top left hand corner or directly click on optional updates to check if new hardware drivers are available for your computer system.

If This does not solve your issue,

For Desktop Computer Systems

  • If you have a Add-on Graphics Adapter Installed, try pulling it out and checking the display on your on-board display option. If you do not have a motherboard with a on-board display, get another card to check if that works or try reseating your present graphics adapter properly into the slot.
  • Check the Display Cable ( Any type ) for damage. Also check both ends of the cable to make sure they are properly plugged in.
  • Check your Display Monitor with another computer of laptop device to make sure you don’t have a problem with your Display.
  • You can alternatively try to plug another monitor into your computer to check if that works properly.

For Laptop ( All portable Computers )

  • Take out your laptop battery, press & hold your power button for a few seconds.
  • Reinsert the battery into the compartment & check if the problem persists.
  • If your laptop shows lines across the screen when you move the display panel ( move the hinges to adjust the display ) then your cable connecting your display to motherboard/display adapter might be wearing out, in this case the only recommended solution is to take the computer to a authorized dealership or support outlet.


  • Your Computer monitor might display some lines across the screen if there is a power surge or when the power input is lower or higher than the recommended range your monitor supports (Most of the time LOWER ), Check the documentation that came with your monitor to confirm the recommended power input.

Block Internet Access over Network but allow Network Access / File & Print Sharing in Windows 8 , 7 , Vista , XP

After reading this guide you will be able to block internet access over a home network or any network that your are an administrator to. This guide is a very simple collection of steps that do not require any additional software or firewall support to block internet access & just allow file & printer sharing.

There are situations where one needs to allow or block internet usage to some users over a network. There are different methods that can be used to do the same, though the most easy method is given below:

Let’s assume that you have a network running with single or multiple routers, either in home or office & you wish to block just the internet access to specific and / or all users. For this you have to login to your router by either IP address or router address & provide your username & password therein. Now in DHCP or DNS setting just uncheck the automatic DNS & mention the DNS settings to be anything you wish. for example: or anything you like except the router’s IP address. 

Now all the computer systems over your network might still show the internet to be connected but will not resolve / open any websites.

To enable network access in a specific computer, just go the properties of the network adapter of that specific computer & within the IP address menu mention any open DNS. i.e or Google DNS would also do.


And that is all there is to it.
