Note when the slowdown happens

Is startup slow, or does the computer freeze only in a particular application? Note an example, the application and approximate time. Save the exact error text if there is one. This helps focus the intervention on the actual problem.

Review before making changes

Limited free storage and many startup applications can slow a PC down. Review storage and startup apps, but do not delete unfamiliar system files. Check Windows updates and run a Windows Security scan.

What to send FixIT

Send the computer model, Windows version and what changed before the slowdown. Do not send passwords or private documents. If the computer is unstable, we first discuss protecting important files. Software optimisation cannot remove the limits of old or faulty hardware.
