Stripes on the laptop screen, what to do?

User question

Hello.

Vertical stripes began to appear on the laptop, even during Windows boot. They did nothing with the laptop (did not drop it, did not fill it, etc.). What could be?

I would like to fix it myself ...

Best regards, Zakhar.

Hello.

It depends on which stripes ... This problem can be both software in nature (for example, due to incorrect drivers), and hardware - in the event of a breakdown of the video card, monitor matrix, etc.

In any case, you can check something on your own (what if the problem is not so serious and you can save on the service ?!).

What to do if streaks appear

STEP 1: connect an external monitor to your laptop

And so, to begin with, you need to connect either a second external monitor (for example, from a PC) or a regular TV to the laptop. This is done quite simply (links below for help):

  • How to connect laptop to TV - //ocomp.info/kak-podklyuchit-noutbuk-k-tv.html

👉 At all, this step will help us diagnose the problem:

  1. if there are no stripes on the external monitor (and on a laptop, at the same time, stripes will be observed in games, in Windows, and in the BIOS) - most likely a problem is either with the loop or with the monitor matrix. In both cases, you can't do without a service;
  2. if stripes are also observed on the external monitor (just like on the laptop screen) - most likely the problem is either with the drivers or with the hardware (video card, motherboard). Those. you can continue looking for the reason ...

STEP 2: set the time and nature of the stripes

Next, I would recommend taking a close look at exactly when the stripes appear:

  1. Immediately after turning on the laptop (i.e. even before Windows boots);
  2. only when it appeared. desktop (i.e. after Windows boots);
  3. after launching some specific games, etc.

👉 By the way, it would not be superfluous to go into BIOS (UEFI) and load secure settings (i.e. reset to factory presets). This will eliminate the problem associated with overclocking (if, for example, someone decided to speed up the device and changed the frequencies manually (although this usually cannot be done on laptops)).

BIOS stripes

Aftertake a closer look if there are stripes when you are in BIOS (UEFI)? If they remain, it is likely that the problem is of a hardware nature (i.e. the device is in service).

If there are no stripes in the BIOS, I would recommend:

  1. first: boot Windows in safe mode (in this mode, only the most necessary software for Windows is loaded. If there are no stripes in this mode, it is worth "digging" in the direction of drivers and the OS itself ...);
  2. second: boot from a LiveCD disk (flash drive). This action will also help identify the problematic driver (Windows installed errors).

STEP 3: if stripes occur intermittently in Windows (they are not in BIOS and when booting from LiveCD)

Not always, but as a rule, this indicates a problematic driver (not a suitable version for the current OS, system errors, conflict with other drivers, etc.).

By the way, not so long ago on one of my work laptops a similar picture with black and green stripes was observed (~ appeared every 20 minutes and only in browsers). The problem was AMD video driver ...

What can you advise:

  1. determine the exact model of the laptop, and download a set of drivers for it on the manufacturer's website;
  2. remove old drivers using specials. software (by the way, the drivers that Windows itself installs in auto-mode can often be the cause of such a problem);
  3. install new downloaded drivers;
  4. if there are no drivers for your current OS on the manufacturer's website, reinstall Windows (it's just that many are switching to Windows 10, and the manufacturer has not released official drivers for 10 ...).

👉 Note: if several versions of drivers for a video card are posted on the manufacturer's website, I recommend downloading them all and checking them one by one (it is not known which version of them will work more stable ...).

STEP 4: if the streaks are observed only in games (or under load, when the laptop starts to slow down)

As a rule (in 98% of cases), this problem occurs due to the video card and its overheating. Banding and distortion on the screen can be very different (examples below).

Example of stripes in games

What can be done:

  1. for a start, it is highly advisable to clean the laptop from dust;
  2. replace thermal paste on the processor and video card (* for advanced users);
  3. purchase special laptop cooling stand;
  4. reinstall the video driver;
  5. install special a utility for monitoring temperature and monitoring if it goes beyond the optimal values;
  6. try to reduce the load on the video card (disable some of the effects in the game, reduce the resolution, set the video card settings for performance);
  7. if none of the above results brought - 👉 to the service.

That's it for now, good luck!
