Hi all... just after some help with my monitor.

When scrolling it shows some yellow or purple lines. I have included a screenshot.

When I try another monitor and cable the problem is still there.

When I try running the graphics off the motherboard instead of my radeon 9800xt the problem is still there.

I have run virus scan and adaware to no effect.

It is mainly visible on white screens but blurs words all over.

The problem also heightens and lessens in intensity for no apparent reason.

any ideas ? any help would really be appreciated.

cheers ! :mrgreen:

A quick, reliable way to narrow this down (and save a lot of guesswork): check whether the problem is recorded in a screenshot. If the saved screenshot file shows the same yellow/purple bands, the corruption lives in the PC/image buffer (drivers, GPU/VRAM, system RAM or motherboard). If the screenshot is clean but the physical screen still shows lines, the fault is in the display path (monitor, cable, connector, or local interference). mentioned a screenshot was attached — confirming which of the two outcomes it shows should be the first step.

Practical triage (ordered to isolate root cause):

  1. Capture a screenshot and view it on another machine.
  2. Reboot and look at the BIOS/UEFI/POST screen before any OS drivers load. If lines appear in BIOS the problem is hardware-level.
  3. Boot from a clean environment (Linux live USB or Windows Safe Mode) to remove the installed-driver variable.
  4. If the artifact appears only under the normal OS, perform a driver-clean (use a safe-mode driver cleaner such as DDU) and reinstall the display driver.

If tests point to hardware: run MemTest86 from USB for several passes and try each RAM stick alone in different slots (RAM faults can be intermittent and cause display corruption, as noted). Inspect the motherboard for bulging or leaky capacitors around the VGA/PCIe area and reseat power/data connectors. As observed, thermal/VRM issues can cause artifacts — monitor GPU/CPU temps with HWMonitor or GPU-Z; avoid stressing a card that’s already failing.

Suggested final order: screenshot -> BIOS check -> live-USB -> memtest and RAM swaps -> visual inspection (caps/contacts/cables) -> temperature/PSU checks. Back up important data early. If artifacts persist through BIOS and on multiple outputs, a board-level fault (motherboard or integrated-video circuitry) is most likely and professional repair or replacement will be required.

Thats a serious problem, the first thing I would check is the graphics card, but i see you have tried that, it may seem like a long shot but you should make sure the connections on your motherboard are fine.
Your PC may have a virus that your virus has not found so I think your last option would be to format your hard disk and start again.

I'm sure someone on the forum can give you a better answer though.

I have had the problem with the bands. It took me a while to realise that it was the cooling, all I did was placed a bigger fan in front of it and the problem went away, when I did some heat testing the card was extremley hot without adding another fan to it. Try hocking up another fan.

Answer

Either the monitor is going bad or the video card is going bad. If you can get your hands on a spare monitor, try swapping it out and see if the lines are still there. If they are, then the problem is with the video card. You'll want to replace the video card if that is the case.

Answer

Ram modules can also cause vertical lines on a monitor.It's hard to believe but i have experienced it multiple times.The ram is detected by the system,yet the display is corrupt.If you open up the pc and touch the ram modules the lines go away.This is very rare yet a possible cause and easily overlooked.

Answer

The video card could be over heating which causes what you are seeing, lines can also be called "Artifacts". Try opening the side of your case and see if you see these lines. Also, it could be a driver issue, try cleaning out your drivers using Driver Cleaner, and reinstalling the appropriate drivers.
If you have another computer, if the video card is a expansion video card (Meaning you have it in a PCI/AGP/PCI-E slot) try it in another computer to see if the problem persists, if so your card is probably bad and needs to be replaced.

Answer

Also check to see if there are any magnets near the screen or hard drive.

Answer

It could probably tell that either the screen is becomming defective or your video/graphic card is overheating or starting to die/fail.

Viruses don't cause vertical lines to appear unless it making it display it.
