My Acer Aspire C24 has recently developed a small band (approx 2 cm width) of vertical lines running down the screen, just left of centre (see attached photo). They are present all the time once the machine is running. I have run various malware programmes, but nothing comes up. Any ideas please?

Thank you.

Hi @Downs2015

You can try to reinstall the display drivers to check if that makes any difference.

NOTE: Make sure to reboot the computer after uninstalling the driver.

Hope it will help you in some way.

Hi Ragsak28,

Thank you for the advice. I tried uninstalling as you suggested but unfortunately it made no difference. Do you have any other ideas? Thank you.

Which C24 model do you have? Are you still in warranty? That could be any of several different things, though most likely either a driver issue as suggested or the cable that runs between the motherboard and display.

Its a C24- 1650. Its less than a year old so should be under warranty (need to check with family member who purchased it). The only external cable is the power supply as the computer is all in one model. I retried un-installing the driver again and even disabled it but no change.

Thank you for the replies. any other ideas would be welcome.

Yeah, the cable is internal, running between the motherboard and the display. It doesn't really matter because you are in warranty and they should just fix it for you instead of having to diagnose and repair it yourself.

We need to determine whether it is a hardware or software issue..  Turn off the computer.  Tap f2 for laptop, del for desktop while turning on the computer.  It will go to bios.  Please stay on the bios screen for 30 mins.  If the display is looking good on bios then it is a software issue.  If the display is not looking good on the bios screen then it is a hardware issue.   If it is a hardware issue since your computer is still under warranty please contact the warranty dept.

If your computer is in warranty you can contact the warranty dept.   Go to the website support.acer.com - chose your country.  On the new page - scroll down - click on "contact support". Scroll down. You can find the phone no to contact the warranty dept. 

If it is a software issue try the following the steps..

Try windows x 

go to device manager 

expand display adapter

right click on display driver - uninstall 

Restart the computer 

It should work fine.. 

If it is still not working 

Uninstall the display adapter from device manager 

Don’t restart the computer. 

Go to support.acer.com 

chose your country 

type snid or chose your model 

go to drivers 

Install the display driver 

It should work fine.. 

if it is still not working and if the display looks very good in bios then you might have to reinstall the windows.
