Speed up a slow PC

Q.  My PC is running really slowly. What can I do to fix it? It’s only a year old but I am ready to throw it away!

Block caller ID

Q. I am a doctor and I don’t want patients to have my cellphone number. How can I call them without showing my number?

A. The temporary way of keeping your mobile number invisible from caller ID is as easy as 1-2-3. Actually, it’s more like *67, and it’s free. Dial that code before the phone number and it will temporarily deactivate caller ID. The process is a little more in depth if you want to disable the feature permanently. Just call your cellphone carrier and ask for a line block. Once it’s done, your phone number will never appear, no matter whom you call. Don’t choose this option lightly, because it is permanent and irreversible. A better option is in your phone’s settings.

Find hidden indoor cameras

Q. We are renting a home this summer. I am concerned about hidden cameras. Where might they be and how do I find them?

A. The laws vary from state to state. In general, landlords can put up cameras outdoors and in public spaces, but they can't put them up, visible or hidden, where a reasonable person would expect to have privacy, such as in a bathroom or bedroom. (Audio recording has much stricter rules than video. In many states both parties need to be aware that the recording is taking place.) Special RF detectors can help you find the cameras.

Rental car mistake

Q. I heard you mention on your national radio show a mistake that people are making when renting cars this summer. It had to do with your phone. Can you please tell me more?

A. When you pair your phone to a rental car using Bluetooth, the car stores your phone number to make it easier to connect later. It also stores your call logs, and possibly even your contacts, which you don’t want sitting around for the next renter. Go into the car’s settings (it will vary by car model) and delete your smartphone from the list of paired Bluetooth gadgets. That should wipe your call log and contacts. If it doesn't, look for an option to clear user data or do a factory reset. Talk to the employees at the car rental place if you can't find these options.
