Solved Answer

Blue Screen of Death[1] is a stop error that most users operating a Windows computer encounter at least once before. The crash happens when the system runs into a critical error, forcing an immediate reboot. This can make people lose their current work or interrupt other activities they are performing at the time.

In most cases, BSODs are a one-time occurrence that automatically resolves themselves after a reboot. The problems start when users start experiencing repeated crashes due to blue screens – it significantly diminishes the usability of the device. This also signifies that there's something inherently wrong, and the issue needs to be looked into.

DellInstrumentation.sys Blue Screen is a relatively new phenomenon that started bothering Dell computer users relatively recently. The issue is rather universal and started with the application of the latest Windows updates for most Dell, Alienware, or other related brand users. The error code provided is usually SYSTEM_SERVICE_EXCEPTION, with the failed Dell component shown as a reference.

The problem lies within Dell launching an incompatible update for their software known as Support Assist. This prompted the related software and drivers' malfunction, resulting in constant DellInstrumentation.sys crashes. Users said that they couldn't even load into their computer properly, without it crashing straight away.

To solve this, you can uninstall the related application Support Assist. If you don't want to lose access to the said software, you can use the previous version of it without problems. Alternatively, disabling its related components, such as services of biometric drivers,[2] can also work. We recommend checking all three options and seeing which one works for you.
