How to analyze e-mail headers the easy way

E-mail messages weren't always as reliable as they are today, but problems can still occur during delivery. Reading message headers can help pinpoint delivery issues, like delays. But if you've ever tried looking at a full message header, you know that it can be a bit confusing to read.

Fortunately, there's a Web-based message header analysis tool that reads the header data for you and outputs it into a format that's much easier to analyze.

To use Message Header Analyzer, first copy the full message header from an e-mail message. If you need help figuring out … Read more

How to start Windows 7 faster

High-performance PC hardware doesn't always deliver the speed users expect. But you probably shouldn't blame the hardware. The slowdown may be due to a software conflict.

A reader named Abe Ibrahim contacted me last week to ask about his slow Windows 7 PC:

My system: Asus Rampage III Extreme MB, Intel i7 980x CPU, 12GB Tri-Bus Memory, 128GB SSD (OS), and 9TB RAID-5 storage. One would think no matter what you ran, the system would scream through it. That is not the case with my system: Windows 7 Ultimate 64-bit boots in 51 seconds... [When] I use it … Read more

Call muting growing issue for iPhone 4S users

Though the biggest gripe for most iPhone 4S users has been an abnormally short battery life, an issue that could prove to be just as frustrating is gaining vocal ground in support forums across the Web.

These iPhone 4S owners are experiencing random muting during phone calls, an issue that has reportedly been ignored in the forthcoming iOS 5.1 update.

The problem happens as calls are placed. You tap the appropriate contact or dial the number you wish to call and at some point during the connection, the audio on the caller's end fails.

Interestingly, on the other … Read more

How to test your RAM in Windows

A bad memory module (RAM) can cause unpredictable behavior in a Windows system, including the dreaded blue screen of death. If you suspect that your RAM may be faulty, you can run a memory test to confirm that you have a bad memory module.

Laptop and desktop PC makers occasionally provide preinstalled utilities that sometimes include a memory test. Feel free to try out those utilities, especially if your computer is under warranty and you want to make a warranty claim. Manufacturers will often require you to run their support utilities first, before agreeing to replace hardware or move forward … Read more

How to fix 95 percent of iOS app crashes

iOS isn't perfect. There, I said it. This will become evident to anyone who's ever tried to figure out Notification Center or organize contacts into groups.

And I guarantee that at some point or another, you've installed a shiny new app, only to have it crash on you, either the moment you ran it or maybe a few minutes in.

Indeed, the App Store is packed to the gills with user reviews like these:

"Crashes about a minute into the game."

"App wouldn't load. Zero stars!"

"Won't run on my iPad 2--crashes right after I tap the icon."

So what's going on here? Bad programming? In some cases, yes. Some apps are just plain buggy. But if you install a new one and immediately have problems getting it to run, there's an easy fix:… Read more

Convenient sharing services for troubleshooting OS X

When managing problems in OS X we sometimes limit ourselves to using the input methods we see in front of us: the monitor, the keyboard, and the mouse. If a problem happens on the system such as a hanging program, we will try to force-quit the program using the Option-Command-Esc hotkey, or even use Activity Monitor or the Terminal to do the same thing.

This approach to fixing problems assumes that your keyboard, mouse, and monitor inputs are working properly; what do you do if they aren't? A common solution is to force the system to restart by holding … Read more

Troubleshooting system sleep in OS X

Generally it only takes a few seconds for a Mac to wake from or go to sleep, but there may be times when it either takes an exceptionally long time or when it will not wake or sleep at all.

If the system takes a long time to wake from sleep, it may be that it is just waking from a deep sleep mode. The computer's RAM cannot store data without power, so in standard sleep modes, RAM is kept active while the majority of the rest of the system is powered off. This allows for quick sleep and … Read more
