“Why do experts say that it is not advisable to install free antivirus software on a PC?”

Are your “experts” selling antivirus software, perhaps? The fact is: The price of a thing does not necessarily correspond to its overall quality or true value. For antivirus apps (free or paid), check the tests results posted by independent agencies such as AV-Test.org. You’ll see that several free apps are among the top-ranked tools. (Of…

“What is the average read write speed of an SSD hard drive?”

(Answer requested by Jane Clark) The range is so wide there’s no useful “average” to quote. For example, the https://ssd.userbenchmark.com/ site lists current real-world SSD write times from 26MB/sec to 3366MB/sec — more than a two orders of magnitude difference! But by checking out that site, and others such as PassMark.com SSD ratings, you can…

“Why must laptop keyboards be replaced? Why can’t they be repaired?”

Keyboards are mechanically complex, with *lots* of little parts —- usually its own multi-layer circuit board containing its own logic chips and firmware, plus wiring and connectors and over 100 separate electromechanical switches, each one itself a little multi-part precision subassembly with a spring, plunger, contact points, a base, stabilizers, a keycap…. (info). Laptop keyboards…

“Is an SSD guaranteed to save all data if removed from PC and then reinstalled?”

No drive — SSD, HDD, magnetic tape, wire spool, paper tape, whatever — no drive can make that guarantee! But the data on any kind of drive should survive the drive’s careful removal, proper storage, and re-installation. Mostly, it depends on how you handle the drive. SSDs should be handled the same as an HDD…

“My laptop mouse/keyboard is not working in Windows7 after an update; but they still work fine in Safe Mode. What should I do?”

Sounds like driver trouble. Something in your regular Win7 drivers isn’t working with the new update; but when your PC falls back to generic drivers (as in Safe Mode), things apparently work OK again. Option 1) Go to your laptop maker’s support site; download (but don’t yet install) the correct Win7 drivers for your exact…

“Will a hard drive that spins at 5400 rpm have a longer more reliable service life than one that spins at 7200 rpm?”

(Answer requested by Jack Swenson) Probably not. The 7200 RPM drive is designed for 7200 RPM. The 5400 RPM drive is designed for 5400 RPM. Both should deliver their statistically-normal full service life at their rated speeds. Now, if you somehow took a 5400 RPM drive up to 7200 RPM, and if it didn’t die…

“Is high disk usage a RAM problem or a PC problem?”

If a PC is running slow despite having reasonably current and otherwise-healthy hardware, then too-little RAM is for sure a prime suspect — especially if the PC was originally configured at the low end of the OS’s RAM recommendations. Of course, if your PC is old, or has an underpowered CPU, or an old spinning-platter…

“What upgrades and modifications have you made to your old netbook?”

I recently wrote about my still-working, antique, “made-for-XP” netbook as part of a fun PC-vs-Mac discussion here. Apparently — judging from the popularity of the post — there are a lot of other people out there maintaining seriously old PCs, too! For example, correspondent “twinmustangranchdressing” asks: “What upgrades and modifications have you made to this…

“How should I check the authenticity of a password?”

(Answer requested by Aditya Verma) If you really mean “authenticity,” that’s a programmatic question, and I can’t help you: You’ll need to hire someone (or learn yourself) to compare whatever password you’re trying to authenticate to whatever database or algorithm or other authentication-source you specify. But if you mean you want to check how good,…
