How to protect your data during OS fixes
Operating systems are the backbone of your device, but they’re not immune to issues. Here are the most common problems we resolve:
“Operating System Not Found” or “Reboot and Select Proper Boot Device” errors often indicate corrupted boot sectors or hardware failures.
Outdated or incompatible drivers can cause crashes, screen freezes, or hardware malfunctions.
New apps or updates may clash with your OS, leading to crashes or performance drops.
Power outages, malware, or abrupt shutdowns can damage essential OS files.
Bloated start-up programs, fragmented disks, or background processes can drag down your system.
