The device malfunctions when a charging cable is connected.
I’ve been experiencing difficulties with my laptop over the last month. When I play demanding games—such as Dota 2, Path of Exile, and Saint Row IV—using only battery power, there are no issues. However, problems arise when I connect my charger. The game begins displaying sporadic red and white pixels throughout the screen, which eventually causes it to freeze and close unexpectedly. If I disconnect the charger, the game returns to its normal state. This also occurs during initial game startup with the charger plugged in; the opening sequence displays these unusual pixels before ultimately crashing. Notably, I’ve encountered a BSOD (Blue Screen of Death) on several occasions, typically accompanied by error codes like SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (netby.sys) or SYSTEM_SERVICE_EXCEPTION. Prior to these crashes, the laptop functioned perfectly when plugged in and not charging. Here are my laptop specifications:
ASUS A46CB running Windows 8.1 Pro 64-bit

Could you assist me in resolving this issue? Thank you.
To quickly identify this problem, we could examine the DMP files; however, I’m unavailable due to work constraints and lack of necessary resources. Assuming no one follows up on this, I anticipate completing the analysis in approximately 7-8 hours. It’s possible a software glitch is responsible, but a hardware defect seems more probable in my opinion. If you report that you tested with alternative power supplies and continued to encounter the same problem after cleaning, and if it turns out to be a hardware malfunction, it could involve a connection between the graphics card and the display – and at 50 degrees Celsius, overheating is unlikely.
Start by uploading the error dumps somewhere. They will help the more tech-savvy users to help you better. You can usually find them under #:\Windows\Minidump (where # stands for your OS partition).
Graphical artifacts are usually (but not always) the sign of a faulty component or of overheating. Since there's a BSOD seemingly caused by a system file, the former option would be more plausible. Let's hope it's not that for now.
I'm assuming that, while the PC is battery powered, the power saving energy profile is set, speeding things down to save battery life.
As soon as the charger is plugged, however, the high performance profile kicks in, removing the limitations imposed by its energy saving counterpart. The laptop thus runs faster, in doing so generates more heat and eventually overheats, generating the said errors.
You can manually set the high performance mode from the battery icon in your tray bar; try doing that when you're on battery and see if it happens again.
If that happens, you may want to open your laptop's bottom covers and blow the dust away with some compressed air or a soft, anti-static brush.
If it doesn't happen, it may be a faulty component. Since it only happens when you plug the charger, it could even be the charger itself. Try using a different (and possibly with a lower voltage output ) one.

Initially, please share the error dumps somewhere; this will assist more technically skilled users in providing better assistance to you. They are typically located at #:\Windows\Minidump (where # represents your operating system partition).
Visual distortions often indicate a malfunctioning part or excessive heat. Given that a Blue Screen of Death (BSOD) is appearing due to a system file, the component issue seems more likely. Let’s hope this isn't the case.
I believe the PC is running on battery power with the energy-saving profile activated, which slows down performance to conserve electricity. When the charger is connected, however, the high-performance setting engages, eliminating these restrictions and increasing speed. This increased activity generates more heat and ultimately causes the errors.
You can manually select the high-performance mode from the battery icon in your system tray; try this when running on battery to see if the issue recurs.
If it continues to happen, consider opening the laptop’s bottom panels and clearing out dust with compressed air or a soft, anti-static brush.
If not, it might be a defective component. Since the problem only occurs while charging, the charger itself could be the cause. Try using an alternative charger – perhaps one with a lower voltage output.
I've uploaded the files to Google Drive (https://drive.google.com/#folders/0B5_t6...fSWtIQ2c); I’m new to this platform, so hopefully it can be accessed.
I don’t believe overheating is the root cause because I use it in a cold environment and confirmed with Afterburner that temperatures never exceed 50 degrees.
I tested different power settings, experimenting with battery-saving and high-performance modes, and found that the problem persisted regardless when plugged in, even with the battery saving profile selected. This led me to realize the issue arises specifically when it's connected to a power source.
I’ve cleaned the bottom of the laptop, but the problem remains. I borrowed an ASUS charger with the same voltage and a lower one, yet the error persists.
I’ve noticed that the issue isn’t limited to games; it also affects photo editing. When opening an image, it displays random pixels, which gradually disappear after viewing several images. However, if I close the viewer and re-open the image, the problem reappears. Strangely, this doesn't occur with video files.
To quickly identify this problem, we’d examine the DMP files; however, I am unavailable to do so due to work constraints and lack of necessary resources. If left unattended, I anticipate completing this analysis within approximately 7-8 hours. It could potentially be a software malfunction, though a hardware defect seems more probable in my assessment. If you report that you tested with alternative power supplies and continued to encounter the same problem after cleaning, and if it’s determined to be a hardware issue, it may relate to the connection between the graphics card and the display – and at 50 degrees Celsius, overheating is unlikely.
Well if your game crashes when plugged in I recommend dusting your laptop or there is another way:
I got another way of helping you see programs like these such as video games use too much performance you can decrease their graphics manually in settings and it will work for you. I have used it after 1 week of searching it will work here is how:
Open settings then look for systems first tab don’t search it click on display then scroll down go to graphics settings then you want to browse that application click on it then click on options you will find power saving you click on it and if it’s from the microsoft store there is desktop app tab click on it and click on microsoft store app I hope that helped
