• SMART Drive Analysis. This function reads and interprets SMART (Self-Monitoring, Analysis and Reporting Technology) attributes of HDDs, SSDs, and NVMe drives. It displays critical values such as error counts, power-on hours, operating temperature, and estimated remaining lifespan for failure prediction.
• Real-Time Temperature Monitoring. Collects data from thermal sensors integrated into the CPU, GPU, and storage drives. It presents the readings in a unified interface, allowing observation of the system's thermal behavior under load and at rest.
• Complete Hardware Inventory. Scans and lists all installed hardware components, including model, manufacturer, serial numbers, and firmware versions. It covers the motherboard, processor, memory modules, graphics cards, and storage controllers.
• SSD/HDD Health Assessment. Assigns an overall health status (e.g., Good, Caution, Critical) based on the combined analysis of multiple SMART attributes. It uses algorithms to weigh the importance of parameters such as reallocated sectors or the wear level on NAND cells.
• System Resource Usage Visualization. Displays real-time utilization metrics for the processor (per core), RAM (physical and virtual), and graphics card. It includes clock frequencies, load percentages, and dedicated/shared memory consumption.
• Configurable Alert and Notification System. In the Professional edition, it allows setting custom thresholds for temperatures, SMART values, or operating hours. When these limits are exceeded, it generates alerts via Windows system notifications or email sending.
• Detailed Diagnostic Reports. Generates text or HTML documents containing the complete system analysis summary. These reports include technical specifications, health statuses, performance metrics, and collected historical data, useful for archiving or technical support.
• Background Monitoring. Runs a memory-resident service that continuously monitors selected parameters without user intervention. It logs data at programmable intervals to create a history of performance trends and hardware health.
• Detailed Operating System Information. Gathers and presents data from the Windows installation, such as version, build, installation type, product key, last update date, and computer name, integrating this data with the hardware context.
• RAM Analysis. Detects the type, size, speed (frequency), manufacturer, and configuration of the installed memory modules. It displays current usage and the percentage of available memory, complementing the information with XMP/AMP profile data if active.
• CPU Specification Detection. Identifies the processor model, number of cores and threads, cache, microarchitecture, socket, and Thermal Design Power (TDP). It monitors the dynamic frequency, voltage, and utilization percentage of each core individually.
• Graphics Card (GPU) Inspection. Obtains information from the integrated or discrete GPU, including model, manufacturer, amount of VRAM, driver version, and bus width. It monitors temperature, core frequency, and utilization during graphics tasks.
• System and Drive Uptime Tracking. Records the total power-on hours of the computer and of each storage drive separately. This data serves as an indicator of the age and accumulated wear of mechanical and electronic components.
• User Interface with Unified Dark Theme. Presents all information in a main window structured into logical sections. It uses a dark color scheme that reduces eye strain during extended monitoring sessions.

PC Internals is developed by ASCOMP Software, a company specializing in utilities for Windows systems. The program was initially created to address the need for a comprehensive and accessible hardware diagnostic tool. Its development began several years ago, primarily using the C++ programming language to achieve low-level hardware access and efficient performance. Periodic updates incorporate support for new hardware components, interface standards like NVMe, and improvements in SMART data interpretation algorithms.
