5 Things You Should Do Before Buying a New Computer

When a computer gets slow, frustrating, or unreliable, the natural instinct is to replace it. And sometimes that's the right call. But a lot of the computers I see in homes throughout Athol and Gardner are perfectly repairable — and their owners are on the verge of spending $500 to $1,000 on a new machine when a $60 upgrade would solve the problem.

Before you buy a new computer, go through this list. You may save yourself several hundred dollars.

1. Find Out If You Have a Hard Drive or an SSD

Open File Explorer, right-click on your C: drive, and select Properties → Hardware. Or open Device Manager and look under "Disk drives."

If the description contains words like "HDD," "RPM," or the manufacturer names "Seagate," "WD Blue," or "Toshiba" — you likely have a traditional spinning hard drive. If it says "SSD," "NVMe," or "Samsung EVO," you have a solid-state drive.

Why this matters: Replacing a traditional hard drive with an SSD is the single most impactful upgrade available for a slow computer. Boot times go from 3–5 minutes to under 30 seconds. Programs open faster. The computer feels noticeably newer. The cost is typically $60–120 for parts plus labor. If your computer is slow and has a spinning hard drive, this is almost always worth doing before replacing the machine.

2. Check How Much RAM You Have

Press Ctrl + Shift + Esc to open Task Manager, then click the "Performance" tab and select "Memory." This shows how much RAM you have and how much you're using.

If you have 4GB or less: This is genuinely too little for Windows 11 to run comfortably with modern browser tabs and applications. A RAM upgrade (typically 8GB or 16GB) costs $30–60 for a laptop and may solve the slowdown entirely.

If you have 8GB and it's consistently above 80% usage: Upgrading to 16GB is likely worth it, especially if you keep many browser tabs open.

If you have 16GB or more: RAM is not your problem.

3. Run a Malware Scan

Download Malwarebytes (free version at malwarebytes.com) and run a full scan. Malware — especially cryptocurrency miners — can make a computer feel dramatically slower by consuming CPU and memory in the background.

If the scan finds infections and removing them doesn't fix the slowness, the issue is hardware or software. But ruling out malware first is important, because no amount of hardware upgrading will fix a performance problem caused by an active infection.

4. Check the Age and Condition of the Hard Drive

Open the Windows search bar and type "Windows Memory Diagnostic" — but what you actually want is a hard drive health check. Download the free tool "CrystalDiskInfo" and run it. It reads the S.M.A.R.T. health data from your drive and will show "Good," "Caution," or "Bad."

If it shows "Caution" or "Bad": Your hard drive is failing and needs to be replaced. This is almost certainly the cause of your slowness and reliability problems. A replacement SSD is far cheaper than a new computer — and your data can usually be preserved.

If it shows "Good": The drive is healthy. The slowness has a different cause.

5. Get a Second Opinion Before You Buy

If you've checked the above and you're still not sure whether to repair or replace, call a technician before spending money on a new computer. A 30-minute in-home assessment is far cheaper than an unnecessary new computer.

I tell customers honestly whether their computer is worth repairing. If the repair cost exceeds roughly half the cost of a comparable new computer, replacement usually makes more sense. But in many cases — especially for computers that are 4–7 years old with traditional hard drives — repair is clearly the better value.
