Is My Computer Worth Repairing?
Generally worth repairing if the fault is contained (one component) and the computer otherwise still meets your needs. Less worth repairing if the computer is very old, already slow beyond the current fault, or the repair cost is a large fraction of what a replacement would cost.
Questions worth asking first
How old is the computer? Was it meeting your needs before this fault? Is this the first significant repair, or one of several? A single contained fault on a computer that was otherwise working well leans strongly towards repair.
When it tips towards replacement
A computer already struggling with everyday performance, needing multiple repairs, or old enough that parts are becoming hard to source, is a weaker repair candidate — particularly if the repair cost is close to what a new equivalent computer would cost.
Getting a straight answer
A proper diagnosis gives you the actual fault and actual cost to compare against replacement, rather than guessing. This page will be expanded with clearer decision guidance in a future update.
