The White Screen of Death is a phenomenon characterized by a white screen being displayed instead of the intended output, like in the Blue Screen of Death in Windows.
This situation is caused by problems in the software, hardware, and incompatible settings and usually indicates a major issue.
The ways of dealing with WSOD are: checking the cables, modifying graphics settings, restoring the driver, connecting to another monitor, and testing the hardware such as the motherboard and the display.
If these actions prove ineffective, one should seek assistance at the service center of the manufacturer or a technician.

Unraveling White Screen Problems at Startup
The reasons for getting a white screen after laptop startup or when the OS loads are mainly associated with either software malfunctions or hardware issues. If everything appears to be okay and the operating system works without problems, most likely it is the virus attack or a badly configured video card driver that leads to the sudden occurrence of a white screen. When it comes to the situation where the white screen starts appearing straight after the power-on of the laptop and there is no access to safe mode, checking the functionality of some system parts becomes extremely important. Here is what needs to be done.
In case the computer fails to boot properly preventing you from conducting the virus scan or identifying a driver problem, you will need to enable the special safe startup mode. This approach works equally well for all Windows versions.
If all attempts to boot your laptop in safe mode are in vain, get ready for taking drastic measures and create a bootable USB flash or CD/DVD.
Method 1: Eliminating Malware
The existence of viruses and malicious programs installed on your hard drive usually results in a series of serious OS troubles. When your laptop boots normally but the white screen appears during usual work, perform the full system scan with a reliable antivirus tool. There is a number of high-quality products allowing users to detect and delete all unwanted programs from the computer storage.
Method 2: Drivers’ Reinstallation
Sometimes software errors can occur due to incorrect installation or regular updates. Such problems result in various errors, including the appearance of a white screen. Most likely, the reason for this problem is the malfunction of the graphics chip or monitor driver. In such a situation, the solution is to reinstall or roll back the driver.
It can be done either by means of the built-in utilities of Windows or third-party programs. The special software automatically detects and installs all necessary components, thus restoring the normal functioning of your laptop.
Method 3: Connecting the Laptop to an External Monitor
In order to check for hardware problems in the graphics chip or monitor, connect your laptop to an external monitor such as a TV set or a computer monitor. Most modern laptops have the HDMI ports making it easy to connect the external display. There is a possibility that the other standards such as DVI, VGA, or Display Port should be used. It also can be assumed that the problem concerns the internal display, which may be mechanically damaged and require replacement. Before choosing a new panel, compare the screen size, resolution, connector type and position, mounting brackets, and refresh rate. A specialized laptop parts supplier such as Zeto.ua can help match these parameters to the exact laptop model, while Rozetka and iFixit offer broader catalogues where compatibility usually requires more careful verification.
Enabling the External Monitor Manually
In some cases, the laptop cannot detect the attached external device after startup. In this case, you will need to enable it manually with a corresponding key combination — typically, it is Fn + F4 or Fn + F7.
Checking the External Monitor Image
If the external monitor displays a perfect picture without any defects or white screen errors, it can mean that something went wrong with the video card. In this case, take your laptop to the repair service where specialists will be able to detect the source of the problem and fix it.
Method 4: Establishing Motherboard-Display Panel Connection
The flat cable is the connector that establishes the connection between the motherboard and the display panel transmitting the image. The damage or malfunction of this cable may result in the white screen at startup. To restore the connection, follow the instructions below:
- Dismantle the laptop case according to the manufacturer’s instructions. In case you do not have such, refer to the manuals for dismantling offered on the official web pages of the equipment manufacturers.
- Find the flat cable responsible for proper interaction between the motherboard and the display panel.
- Check the cable for damage or any defects. If nothing was found, disconnect the flat cable with the help of special tools and reconnect it. Sometimes it happens that the cable gets disconnected as a result of mechanical impact.
- After reconnecting the cable, put together the laptop and boot it. In case of physical damage, the laptop should be serviced in a special center.
