My six-year-old PC stopped working, and I was told the RAM may be faulty. I need 16GB of replacement memory, but the DDR4 kit I want costs around $200, while cheaper kits are still roughly $150. That makes buying temporary RAM feel wasteful.
A store employee suggested upgrading to a newer CPU, motherboard, and DDR5 memory bundle instead, since DDR4 parts are becoming less common. However, the DDR5 kits I'm considering start around $500, and I would also need a new motherboard and CPU. Used or open-box kits are available for around $300, but I'm unsure whether they're worth the risk.
I don't currently have enough money for a complete upgrade, so choosing DDR5 could leave my computer unusable until I save more. I would like to keep this PC running for at least another five years. Should I simply buy DDR4 now and upgrade the rest later, or is moving to DDR5 worthwhile? Also, is refurbished DDR4 memory a reasonable option if I can get 32GB for the price of a new 16GB kit?

Before spending anything, make sure the RAM is actually defective. Run a proper memory test, reset the BIOS or clear the CMOS, and test with XMP or EXPO disabled. If the modules really are bad, check the manufacturer’s warranty first—many memory kits have lifetime coverage, so an RMA may be much cheaper than replacing them.
Look at complete platform bundles rather than pricing each part separately. Some CPU, motherboard, and 32GB DDR5 bundles can be good value, but compare the total cost and expected performance against simply replacing the failed RAM. Since you want to use the computer immediately, I would not choose an expensive upgrade solely for future-proofing.
Open-box parts can be safe when they come from a retailer with a clear return policy, but I’d avoid private sales unless the seller allows testing or returns. Memory compatibility and stability are more important than getting the absolute lowest price.
If you’re on a platform that already supports DDR4 and you’re trying to control costs, buying compatible DDR4 is the sensible choice. A used or refurbished 32GB kit from a reputable seller can be fine, as long as it has a return period and you test it thoroughly. Keep the current CPU and motherboard, then put the money you save toward a future platform upgrade.
The answer depends on your current CPU and motherboard. Older platforms may make a new CPU, board, and DDR5 bundle a reasonable long-term upgrade, while newer DDR4 platforms can still perform very well. DDR5 by itself is not a compelling reason to replace a working system, especially if the upgrade would leave you without a computer for months.
I did some testing and troubleshooting and originally suspected the power supply, but the store diagnosed the problem as faulty memory. I’ll still check the warranty and retest the modules.
