Notice when it struggles
Does starting up take ages? Does it slow down with several programmes open? Is only one application affected? A few specific examples are more useful than simply saying the computer is slow. Note any error messages too.
Check the whole picture
The age and condition of the device matter alongside speed. Consider the battery, screen, keyboard, available storage, and whether it can run supported software. A fast new component cannot fix every limitation.
Compare realistic options
A repair addresses a fault. An upgrade changes a component, such as memory or storage, where the device allows it. A replacement may make more sense when several parts need attention or the computer no longer fits your needs. Have compatibility checked before buying parts.
Plan for your files and applications
Before work begins, identify the documents, photos and applications you rely on. Check your backup and make a note of any software licences you may need. Ask what can be moved, what needs reinstalling, and what each option will cost.
The useful bit to remember
The best choice is the one that suits the computer’s condition, the work you do and your budget. Start with an assessment.
