The driver overran stack buffer error, also known as DRIVER_OVERRAN_STACK_BUFFER, is a fatal exception that occurs when the driver of a device caused an overflow by sending more data to the device than it could handle.

This error often appears when the driver is trying to read or write to a memory buffer larger than what the hardware can handle. It can make your computer unusable and force you to restart it.

What is a “Driver Overran Stack Buffer?”

A driver overran stack buffer is a part of a small memory region called stack which can be used by the operating system and application software. Occasionally, when the driver overruns the buffer, it will crash and cause errors with the PC.

One reason for crashing may be an improper assignment that instructs the data to be copied to the wrong location. Software professionals should take particular care in programming this area because it is such an integral component of any computer system.

A driver overrun can occur when the driver is misconfigured or when the driver is not an operating system component. In the latter case, the driver simply doesn’t have access to the memory area.

Many Windows users are familiar with the common error of “Driver Overran Stack Buffer” that pops up on their screen. This article will walk you through some of the possible solutions for you to follow if you have installed a driver overran stack buffer error on your computer.

What Causes The Driver Overran Stack Buffer Error?

Why Do Drivers Overran Stack Buffer On PC?

Stack buffer overruns happen when a program writes more data to a buffer than the buffer is allocated to hold. This might happen because the programmer doesn’t know how big the buffer should be, or because they mistakenly think that it’s bigger than it is.

This can lead to serious consequences such as data corruption and system crashes.

How Do I Run A BSOD Troubleshooter?

To run a BSOD troubleshooter, you need to download and then install the Windows Memory Diagnostic Tool. This tool will automatically detect any memory problems in your system and offer you the option to fix them.

Can CPU Cause Blue Screen?

Yes, the CPU can cause a blue screen. This is because the CPU has a lot of power to process tasks. If the CPU has not been cooled down for a long time, it can overheat and cause the computer to crash.

What is Windows Stopcode?

Windows stop code is the error message that is often displayed on your screen when your computer crashes or freezes. It has a signature, “STOP 0x0000007B (0xC0000034, 0x00000000, 0x00000000, 0x00000000)” with the numbers varying in order and location.

If you are seeing this message then it means that there is some problem with your computer that is preventing it from operating correctly.

How Do I Fix The Uncorrectable Blue Screen When?

If you are experiencing the blue screen of death, you will need to go into safe mode and then run a system file check. If that does not work, you will need to do a repair install.

What is Status Stack Buffer Overrun?

Status stack buffer overrun, or simply buffer overruns, are a common programming error that is often the result of not correctly specifying the length of an array.

When an algorithm refers to a memory location for accessing data and the address is incorrect due to insufficient bounds checking, it will read from adjacent memory as well as overwrite.

Is Windows Stopcode A Virus?

Windows Stopcodes is not a virus, but the name is misleading. If your computer freezes and you restart it, you may be in for a long wait because your computer may need to start over. This has happened to me before and took me about an hour to get my work back.


In a nutshell, a driver crashes because it overruns a stack buffer of memory. If the buffer is too small, then all of the data that was sent to it will overflow and crash the computer. The solution to this problem is to have a larger buffer size so that the data won’t overflow.

Driver overran stack buffer errors occur when drivers are not given enough memory to function properly. The driver will quickly seize up and cause the computer to crash. Unfortunately, there is no way to prevent this. Instead, the only solution is to reinstall the faulty driver.
