Windows 7 Random freeze/lag

It sounds like you're facing computer freezes or hangs intermittently, and you've already taken several troubleshooting steps to address the issue. Here are some additional suggestions to help you resolve the freezing problem: 1. Check Windows Event Viewer: Look into the Event Viewer for any error messages or warnings at the time the freezes occur. This can give you more insight into what's causing the freezes. 2. BIOS Updated: Even though you mentioned having issues updating the BIOS due to file size errors, it might be beneficial to troubleshoot this further. Check the motherboard manufacturer's website for any BIOS updates and follow their recommended method for updating. 3. CPU Overheating: Despite normal idle temperature readings, monitor the CPU temperature during heavy tasks or when the system freezes. Overheating can sometimes cause freezes. Use applications like HWMonitor to keep an eye on temperature readings. 4. Testing Hardware Components: Perform a thorough hardware test, including stress testing the CPU, GPU, and RAM to ensure no faulty components are causing the freezes. 5. Drivers and Windows Updates: Check for the latest drivers for all your hardware components, especially the graphics card and chipset drivers. Ensure that Windows is fully up to date with the latest updates installed. 6. Resource Monitoring: Monitor system resources (CPU, memory, disk usage) in Task Manager when the freezes occur to see if there is unusual behavior, spikes, or high usage that could point to a specific component or process causing the issue. 7. Startup Processes and Services: Review the startup programs and services that run during startup. Disable unnecessary startup items using Task Manager or MSConfig and check if this helps. 8. System File Checker (sfc /scannow): If the System File Checker found errors, try to resolve them by running the command in an elevated Command Prompt and see if it helps stabilize the system. 9. Software conflicts: Any new software installations or updates coinciding with the freezes? Consider rolling back recent software changes or performing a clean boot to rule out software conflicts. If you continue to face freezing issues, consider seeking professional help to conduct more in-depth diagnostics to isolate the root cause of the problem.
