Ask the Geeks: We answer your tough tech questions

  • Tech Q and A logo

Desktop vs. Tablets

Q. I want to buy my mother something so she can video chat with me and her grandkids. Would a tablet or desktop be a better buy?

A. It depends on what else she would want to use the gadget for. Skype works on both desktops and tablets, though you'll have to buy the webcam separately if you go with a desktop. Tablets have cameras built in, which means you don't have to buy two things. A tablet is going to be cheaper and will work well if she just wants to read webpages and check her email. If you think she might like to do more than that, such as organizing photos, you're going to want to spend the extra for a computer.

Should you buy the Chromebook Pixel?

Q. I heard Google just made its own laptop. How would it compare to a Windows or Mac laptop?

A. Not well. Though Google's laptop has nice hardware specs and a gorgeous body, it costs $1,300 or more depending on how you set it up. Since it runs Chrome OS -- a beefed up version of Google's Chrome browser -- there's not enough it can do for that huge price tag. You'll be much happier buying a MacBook or Windows Ultrabook. It will do much more for the same amount of cash. If you want to try out a Chromebook, look into the sub-$300 models made by Acer and Samsung. They're much better values and run Chrome OS just as well.

Stop harassment on your smartphone

Q. Someone at a certain number won't stop calling and texting me. Is there any way I can block them from harassing me?

A. Each carrier has its own special way of dealing with this. Most make you sign up for a service that usually lets you block a group of numbers for about $5 a month. Sprint is the only carrier that lets you block numbers without paying a fee. Some apps, like Mr. Number, let you block numbers automatically. There's no official way to do it on iPhones, though. If you have an iPhone, you can set up a contact labeled "ANNOY" or "SPAM" with a silent ringtone and notification. You can add new numbers to it as you go.

Turn off 4G?

Q. I just got my first smartphone, but I'm breezing through data too fast because I'm on 4G. It's also devouring my battery life. Is there any way to turn it off and only use 3G?

A. You can turn off 4G on any gadget that has it, if you want. This can save battery and slow down your data consumption. To do it on an iPhone, go to Settings > General > Cellular and slide "Enable LTE" to Off. For Androids, go to Settings > Wireless & Networks > Mobile Networks > Network Mode and choose the option without LTE. 

For Windows Phone 8, go to Settings > Mobile Networks and change the highest connection speed to 3G. You may see the option to turn on or off HPSA+. This is a slower version of 4G that's not as rough on battery life. Leave it on if you want a little more speed with good battery life. Test your speed on each network with SpeedTest before you disable anything, though.

Worth upgrading to Internet Explorer 10?

Q. I saw that Internet Explorer 10 is available for Windows 7, now. Should I upgrade?  

A. Definitely. Internet Explorer 10 is a little faster and much safer than previous versions of IE, even IE 9. For those who want to stick with IE 9, beware. Microsoft may automatically upgrade you soon if you're signed up for automatic updates. This download can stop that. For those running Vista or XP, you don't have the option of installing IE 10. However, you can run the latest versions of Firefox or Chrome. These are just as fast and safe as Internet Explorer 10, and their interface will be a little more familiar.

Ask the Geeks: We answer your toughest tech questions

Uninstall programs for good

Q. I tried deleting a program from my computer, but it keeps coming back. Is there any way I can get rid of it for good?

A. The problem usually lies in your registry. To clean the old program data out, you can use a program like CCleaner. Stick with the default settings for the best results. Next time you uninstall a program, try a third-party uninstaller like Revo Uninstaller. It does a better job of removing program leftovers. Macs don't have a traditional registry, so you have to clean programs from various places. Try a program like App Cleaner to speed up the process.

Test your computer's security

Q. I've installed an anti-virus program, but I want to test it. How can I make sure it's working?

A. For anti-virus software, you sometimes have to operate on the "no news is good news" plan. There are dozens of things that claim to help you test your security software, but many of these are scams. You can run the risk of actually installing a virus on your computer, too! Your best bet is EICAR for testing anti-virus and Spycar for testing anti-spyware. They're both harmless text files that are coded to look like viruses so your security software catches them. They won't do any harm if your software doesn't catch them, though. If it doesn't, however, make sure you update it or install a new program that can detect them.

Decide which programs to delete

Q. I want to delete some programs to free up some space on my hard drive. What programs should I look for?

A. Should I Remove It? is a good download to help you decide what programs you don't need. It scans all of your programs and ranks them based on what other users have kept or removed. After you've deleted the programs it recommends, use a program like WizTree to see what other programs are clogging up your hard drive. If a program you only use sparingly is taking up a lot of space, search online to see if there is a better, more space-friendly option. If there isn't, decide whether you really need the program enough to justify the space it's taking up.

Stop spam texts

Q. I keep getting the same spammy texts from different numbers. Can I stop these?

A. First, make sure you don't reply. A reply just tells spammers they've hit a working number and you'll get even more spam! Your carrier will usually offer a way to block numbers, but that sometimes costs money. Luckily, there are some apps that can block numbers from harassing you. Google Voice can help you block numbers and mark them as spam. Android-only Mr. Number does the same thing and even features a built-in caller ID so you can screen calls more effectively.

Create budgeting spreadsheets for free

Q. I want to make a simple budget spreadsheet, but I don't want to buy Microsoft Excel. Are there any programs that can help me out?

A. Sure thing. First, let me recommend budgeting sites like Mint, as they do most of the work for you. If you want to do it yourself, the free LibreOffice features an Excel-like program in addition to a free word processor and more. Google Docs also has a spreadsheet program. If you need some help creating your documents, Microsoft offers hundreds of free templates that include budget spreadsheets. Just make sure your program of choice works with the .xlsx file format - both LibreOffice and Google Docs do.
