Test Your PC With 10 (Mostly) Free Sites and Tools Is your PC healthy? Don't be too sure. Think back to when you heard a kerklunk sound coming from the hard drive. Or maybe you remember the last time your Internet connection was down (and I don't mean just a little depressed).
Is your PC healthy? Don't be too sure. Think back to when you heard a kerklunk sound coming from the hard drive. Or maybe you remember the last time your Internet connection was down (and I don't mean just a little depressed).
The best way to find out what's wrong is to take a proactive approach: Check under your PC's hood with the following mostly free diagnostic tools, and see if anything is amiss--before disaster strikes.
Hard Drive Health
Hard drives are about as stable as the stock market. The more you know about your drive--the brand-specific idiosyncrasies and the diagnostic sounds that drives produce--the better prepared you are for the inevitable crash. Here are a couple of helpful services and programs.
Hard Drive Inspector: This utility is always on guard, monitoring all your drives for spin rate, seek time, and almost 20 other potential problem spots. Hard Drive Inspector gives you technical data, including the drive model, firmware version, and serial number, all things you'll need to know when calling for warranty support.
It displays the hard drive's temperature in the system tray. If the drive gets too toasty (I have mine set for 120 degrees Fahrenheit), the program can send you an e-mail alert--or, better, automatically put the computer in Standby mode.
You can view a summary health report, which typically has enough information for most users; the S.M.A.R.T. report has the details. The program costs $30, but you can download a 15-day trial version of Hard Drive Inspector to get a feel for the tool.
DataCent's Hard Drive Sounds: You shouldn't hear more than a low hum from your hard drive. But drives don't know the rules, and they often make weird sounds, emitting thuds, screeches, knocks, or whining. Determining whether one of the sounds means trouble can be, well, troublesome.
The data-recovery company DataCent has an extraordinarily helpful site that plays the actual sounds of bad or unstable drive heads, stuck spindles, wobbly bearings, and media with bad spots, to name a few. You can hear your specific drive brand.
The company also offers another valuable tool that lists typical hard-drive failures by manufacturer.
Broadband Speed Tests
Does your broadband Internet connection feel more like a sluggish dial-up link? Put it to the test by recording your connection speed every 30 minutes or so for a couple of days. Keep a log, and if the speed is nowhere near advertised rates, send the results to your ISP--and raise a ruckus. If you complain vigorously yet politely, chances are good that the provider will have you back at full speed ahead in short order. With all of the following tests, resist the temptation to check e-mail or browse the Web while testing, so as not to alter the results.
Quick tip: If any of these online tests don't work, give me a call for help. Just kidding--instead, make sure you have the current version of the Flash Player; if not, download and install it.
DSLReports: The granddaddy of online testing, DSLReports gives you a stack of tests to try. The Speed Test has a cool car-dashboard-like interface that watches your upload and download speeds.
You can test your speed by using any of six servers in different locations. You'll obtain a good average by testing with two; try one close to home and another across the country.
If you're worried about your connection while gaming, use the site's Line Quality test to look for packet loss and excessive latency. Make sure to register and log in when testing--that way you can compare results months apart.
Speedtest.net: You'll see pretty much the same results from broadband speed testing at Speedtest.net. But this site is quicker to get to than DSLReports, and it has an oh-so-nifty interface, the kind you want to show off when friends are in your office.
Internet Connection Quality
In addition to running overall speed tests, you can use other tools and tricks to improve your online experience.
VoIP Speed Test: If you're making phone calls over the Internet, make sure you have the bandwidth--as well as the quality of service--to get decent VoIP sound, using the VoIP Speed Test.
The bandwidth analysis tells you the percentage of VoIP service quality to expect from your connection, as well as the number of concurrent VoIP lines your connection can support.
Down for Everyone or Just Me: You head for a Web site, but you get an error. I know you've said it:
"Is the site down, or is it my problem?"
Now there's a way to find out. Type a Web site's URL into Down for Everyone or Just Me? (a smartly named site, no?), and it will give you the scoop. Very handy--using it keeps you from bothering coworkers or members of your buddy list.
Fixes for Wi-Fi woes: If you use Wi-Fi, turning your router's Quality of Service (QoS) settings on will definitely help with some applications. For more, see our story "Optimize Wi-Fi for VoIP,
Video, and Gaming," which has tips for tweaking the data transmission speeds of your wireless network.
More Internet advice: To give your Internet connection a goose, see "Internet Boosters." And to prepare for the times when your connection gives up the ghost, check out "Five Quick Fixes for
Internet Connection Hang-Ups."
Inside Your PC
Not everyone can recite the MAC address of their PC's network card or the driver version for their graphics board (not even me). If your computer is hiccuping, knowing exactly what hardware and system software you have inside your PC is invaluable.
For troubleshooting, being armed with such details is ideal: You can pass them along to tech support, to your computer guru (no, definitely not me), or to an online help forum.
PC Pitstop: If you want to visit just one site to test your PC, I'd recommend PC Pitstop's Full Test. This comprehensive tool not only gives you an unbeatable hardware report but also alerts you to various potential problems that could be harming performance.
After I used it recently on my machine, PC Pitstop recommended 11 fixes, gave me a 35-count list of system specs, provided an even longer list of installed hardware, told me what drivers I needed to upgrade, tallied almost 40 performance results, and--get this--compared my PC's ratings with those of all the other computers that PC Pitstop has tested.
If you create a free account, you can save the reports and refer back to them. One warning: If you have a pop-up or ad blocker, disable it before starting the tests.
Belarc Advisor: You can put your PC on the couch and run the free Belarc Advisor to obtain an inventory of your system's hardware. But that alone is no big deal. Where Belarc shines is in its comprehensive analysis of the software installed on your PC, including the version numbers.
Equally useful is the report of Microsoft security hotfixes that are missing from your system, as well as the list of software licenses. After you run the scan, save the HTML page in a safe spot so that you can refer to it if the worst happens.
SIW--System Information for Windows: You can ask the SIW tool anything about your PC--it'll give you a list of regional settings or scheduled tasks, or which DLLs are loaded and which are shared.
How about which video and audio codecs you have installed, or details about your network or open ports? SIW has everything, offering lists that you can easily access from toolbar shortcuts or from a panel with a hierarchy list.
By the way, because SIW is a stand-alone utility that you don't need to install, it'll run directly from a USB flash drive, a floppy (if you still have one), a burned rescue CD, or a network drive.
Be careful: Unless you uncheck the Add Crawler Toolbar to IE and Firefox box during the installation, SIW will automatically install that toolbar and make it your default search provider.
Not a cool thing for such a useful tool to do.
