Check for Malware: Run a full system scan using Windows Defender or a trusted third-party antivirus tool to eliminate the possibility of malware causing the issues.

Run System File Checker (SFC): Open Command Prompt as an administrator and run sfc /scannow to repair corrupted system files.

Check Disk Integrity: Use chkdsk /f to check and fix file system errors on the hard drive.

Event Viewer Analysis: Use Event Viewer (eventvwr.msc) to review logs for specific errors or warnings that might indicate the source of BSODs or crashes.

Use System Restore: If the issue began recently, consider using System Restore (rstrui.exe) to revert the system to a previous stable state.

Memory Diagnostic: Run the Windows Memory Diagnostic Tool (mdsched.exe) to check for faulty RAM, which could be causing BSODs.

Boot in Safe Mode: If the problem persists, boot the system in Safe Mode to see if the issue occurs without third-party software. This can help identify if a startup application or service is causing the problem.

Upcoming Apple Products Guide: What's Coming in 2024 and Beyond
September 2024
In September, Apple will introduce the iPhone 16 lineup and new Apple Watch models.

iPhone 16 - The iPhone 16 models are getting an Action button, a Capture button for taking video when the iPhone is in landscape orientation, and vertically arranged rear cameras that will likely allow for capturing spatial video when the device is held in landscape orientation. We're also expecting the iPhone 16 to adopt a faster A18 chip built on Apple's 3-nanometer process.

iPhone 16 Pro - The iPhone 16 Pro models will have larger 6.3- and 6.9-inch displays, but will otherwise look much like the iPhone 15 Pro models. They'll also get the new Capture button for taking video, with the mmWave antenna set to be relocated to the other side of the device. An A18 Pro chip is rumored to be in the works, but it will likely only bring minor speed improvements. An upgraded 48-megapixel Ultra Wide camera is expected, and the smaller iPhone 16 Pro will get the 5x Telephoto camera that was previously limited to the iPhone 15 Pro Max.

Apple Watch X - Apple could have a major Apple Watch update in store for the 10th anniversary of the device. Rumors suggest Apple is planning for a redesigned, thinner Apple Watch X that has a magnetic band attachment system to make it easier to swap out bands and to cut down on the space that bands use up inside the device. New health features are rumored, including blood pressure monitoring for detecting hypertension and sleep apnea detection.

New Apple Watch Ultra - We haven't heard specific rumors about a refreshed Apple Watch Ultra in 2024, but Apple will likely do a minor update to add any new health features that are introduced.

AirPods 4 - New AirPods are expected to come out alongside the iPhone 16 lineup. Apple plans to debut two different models for the first time, one that is lower cost and one that has Active Noise Cancellation (ANC), which has previously been an AirPods Pro-only feature. The ANC version will be the more expensive version, but both are said to have a new design with shorter stems and an upgraded USB-C charging case that has a built-in speaker for Find My.
