Windows 11 Slow system performance and lagging
on my Windows 11 PC, with frequent lagging, delays, and freezing during normal tasks such as opening applications, browsing files, and switching between windows. The issue occurs even when I am not running heavy programs, and I have already tried restarting the computer and checking basic settings but the performance remains slow and inconsistent so I am looking for advice on possible causes and solutions to improve my Windows 11 system speed and reduce lag.DRIVER_POWER_STATE_FAILURE (0x9F) on ASUS X870E-E & Ryzen 9 9950X3D
Hello, I am experiencing frequent BSODs with the stop code DRIVER_POWER_STATE_FAILURE (0x9F). Hardware: ASUS ROG Strix X870E-E Gaming WiFi • AMD Ryzen 9 9950X3D • Windows 11 • Latest AMD chipset drivers installed from the ASUS website • BIOS 2306 (the issue also occurred before updating to this BIOS) Symptoms: • Random BSODs during very light workloads (Outlook, Chrome, PDFCreator). • Today I experienced four BSODs within 20 minutes. • Sometimes the PC can run for about an hour before crashing. • The computer also wakes from sleep by itself every 10 to 15 minutes. Troubleshooting already performed: • BIOS updated. • AMD chipset drivers completely removed and reinstalled. • OCCT CPU and memory stress tests completed without errors. • No WHEA errors reported. • Normal CPU and motherboard temperatures. WinDbg analysis: Bugcheck: DRIVER_POWER_STATE_FAILURE (0x9F) IMAGE_NAME: pci.sys Failure Bucket: 0x9F_3_ACPI_IMAGE_pci.sys Power IRP blocked in ACPI. Device identified: PCI\VEN_1022&DEV_14DB I also found another ASUS ROG Strix X870E-E Gaming WiFi user reporting the same DRIVER_POWER_STATE_FAILURE (0x9F). In that case, WinDbg identified Usb4HostRouter.sys instead of pci.sys. Could this indicate an AMD chipset, ACPI, USB4 controller or motherboard PCIe power management issue? I can provide the minidump files, the complete WinDbg analysis and the Windows Event Viewer logs if needed. Thank you.
Will closing the laptop screen without putting it to sleep damage the computer?
Just switched from a MacBook to a Windows 11 laptop. I'm used to simply closing the laptop lid without manually selecting sleep mode, and I'm concerned whether this action might cause hardware damage or affect the system's lifespan. Need clarification on Windows' default lid-closing behavior and recommended safety settings.
Files that are hidden from view but still occupy disk space
I have files on my Windows PC that are completely hidden from File Explorer and don't show up anywhere I look, yet they are still taking up a significant amount of disk space. I need a way to locate and remove these invisible files to free up storage, but I'm not sure what's causing them to be hidden or how to safely delete them.Quel est le meilleur outil pour compresser fichier pdf sans perdre la qualité

My Windows system is trapped in an endless restart loop immediately after the initial boot logo appears, and I suspect corrupted boot configuration data or missing system files are preventing the operating system from loading properly. I cannot access Safe Mode or recovery options automatically, so I need guidance on using installation media to repair the boot sector or rebuild the BCD store without losing my personal data.How can I convert .ts to .mp4 on Windows 11?
My mom received a couple of homemade DVDs from a family friend and when the files were copied over to the PC they came out as .ts files. Windows 11 won't play them natively and even the default Movies & TV app just throws an error when trying to open them. The goal is to convert .ts to .mp4 so they can be watched easily on any device and maybe stored alongside other home videos. These are family memories so keeping the video quality as intact as possible during conversion is important. Has anyone dealt with .ts files from homemade DVDs before? Would love to know the most reliable ts to mp4 converter on Windows 11 without losing quality or running into playback issues afterward.Windows 11 Best Graphics Settings for Laptops and PCs: The Complete Performance Guide
