Hello
First post so bare with me. I'm getting striped colour lines running down my PC screen and have no idea what the problem is apart from it is not the screen. Thinking it maybe something to do with the video card.
I'm using an old Compaq Presario SR1639UK running Windows 7 64bit.

Any help or advice on this will be greatly appreciated.

Thank You

:welcome:  to the Bleeping Computer forum.

 

 

Stripped lines can be happened either due to a failing video card or, faulty memory modules or a faulty monitor (especially LCD monitors ). Can you please connect the monitor to another working computer and verify whether it is good or note ?.

Hi

 

Please try the below steps. As it involves physically removing components, touch your hand in an unpainted metal part of the cabinet to discharge static electricity before proceeding.

 

:step1: Remove the graphic card and run the system on on-board display. If the system works fine, use a pencil rubber to lean the gold plated contacts of the card and check whether the issue remains.

 

:step2: If on-board display is also shows lines, remove the RAM sticks one by one and check how the system works. A failed memory module can also produce this error so plugging only one module at a time will help us to figure out the bad one.

Hi

 

First of all, check whether the system came with a dedicated graphic card. Remove the system side cover and carefully unplug the graphic card from AGP or PCI Express slot.

Then connect the monitor to the on-board VGA port which can be located on the back panel.

Here is the official service manual which contains detailed instructions on how to remove the side cover, individual components etc.

Works fine without the graphics card in, gave it a clean and tried it again and had the same problem so looks like a new card is needed.

Thanks for your knowledge and help greatly appreciated.
