Signs It's Time to Replace Your Computer
Multiple unrelated faults appearing close together, a repair cost that approaches replacement cost, or a computer that's still slow even after storage and memory upgrades are all signs it may be nearing the end of its useful life.
Patterns worth paying attention to
Repeated, unrelated faults (not just one thing going wrong, but several over a short period), performance that doesn't improve even after reasonable upgrades, and increasing difficulty finding compatible parts are all meaningful signs.
What's not necessarily a sign
A single fault, even a significant one, on a computer that's otherwise been reliable isn't necessarily a reason to replace it — that's a repair-versus-replace decision rather than an automatic replacement signal. This page will be expanded with more detail in a future update.
