Several iPhone users have experienced problems wherein their phones will display an error claiming repair is needed on the device, disallowing use.

Apple Discussions poster Xraycovert writes:

"Abruptly, my new iPhone began, and continues to flash, a REPAIR NEEDED message on the screen. I can only access an SOS."

While for the most part this error does indicate a problem with the phone will need to be fixed, in some instances this error message is being shown erroneously. There are several things users can do to try to fix the problem before contacting Apple support or taking the … Read more

Editor's note: CNET editor and Crave contributor Dong Ngo is spending part of December in his homeland of Vietnam. This is the last in his series of dispatches chronicling his impressions of how technology has permeated the culture there. Click here for more of Dong's stories from abroad.

HANOI, Vietnam--Prior to my trip to Vietnam, I bought a Dell Inspiron 530s desktop computer as a special American gift for my 11-year-old niece in Hanoi.

Despite the relatively light weight and small form factor of the PC, at San Francisco International Airport, I ended up having to pay a $60 overweight fee. This was mostly because the airline significantly lowered the allowed weight for checked-in luggage, and I wasn't aware of that.

Upon arriving in Hanoi, I personally delivered the gift and set it up for the little girl. Everybody gathered around with excitement as they waited for the moment of truth. As I plugged the power cord into the wall socket, we heard a "pop" sound and smoke came out of the tower. I was dumbfounded. "So much for American-standard quality!" I thought to myself.

But it was not America's fault, it was me. As it turned out, Vietnam uses a 220-voltage power standard, while America uses a 110-voltage one. Out of excitement and ignorance, I plugged the computer in without switching the power supply unit (PSU) of the computer to support 220 volts and, of course, it burned! It was pure physics.

What was hard to quantify was my niece's level of frustration and my own disappointment. I personally picked the specs and rebuilt the machine to run Windows XP (from its manufacturer-installed Windows Vista). Just one moment of negligence, and everything seemed ruined.… Read more

To call TuneUp Utilities 2009 useful would drastically understate the situation. The app provides users with a powerful, well-designed utility that accesses the entire Windows maintenance tool set and more in a fast, organized, and easy-to-use series of connected modules.

Temp file management, registry cleaners and start-up program controls are the bread-and-butter of these utilities, and these basics work in TuneUp more quickly and easily than most. However, the app also sports great add-on tools you don't usually see in a utility program. It offers a variety of Internet and program-acceleration tweaks as well as Windows performance enhancers.

Most of the time our Macs run smoothly due to the well-designed Mac OS X (choose your big cat) operating system. But over time, as you download more applications, visit more Web sites, and begin to use up space on your hard drive, your Mac won't run as quickly and smoothly as it did out of the box. Some users reason that it must be a RAM or hard-drive issue, but more often than not it's a question of maintenance rather than inadequate hardware.

I've talked about programs for uninstalling old or unused apps in an earlier post, … Read more

Let's hope Yahoo has finally learned that the maxim "If you build it, they will come" simply does not apply to a social network.

The Silicon Valley mainstay and onetime Microsoft shopping-spree target is quietly shutting down Yahoo Mash, its latest foray into creating a general-interest social network like a Facebook or MySpace.

It's the latest social-networking failure for Yahoo, which was unable to get its earlier "Yahoo 360" network off the ground, and once attempted to purchase Facebook, only to have its billion-dollar offer turned down.

Mash was cute, with a slick interface, … Read more

As it kicks off its Nvision conference Monday in San Jose, Calif., chipmaker Nvidia must be hoping that the N stands for "new" and "now"--and not "no thanks."

Nvidia is trying to shake off a tough second quarter and is staring down a slump in earnings tied to chip glitches and stiffer competition from rival Advanced Micro Devices. The home page for the Nvision 08 conference urges interested parties to "join the visual revolution" and promises attendees two days' worth of "jaw-dropping visual wonderment" in the realms of games, movies, and science.

A big chunk of the graphics chip supplier's woes stem from a $196 million second-quarter charge taken for defective graphics processors. Though Nvidia CEO Jen-Hsun Huang has said that the "failures are only seen in a small percentage of all the chips," Hewlett-Packard and Dell have listed a number of models affected by the glitch.

A possibly bigger challenge is AMD's resurgent ATI graphics chip unit. Huang said in the second-quarter earnings conference call that his company had "underestimated" the price and performance of AMD's latest graphics chips, leading Nvidia to "to misposition our fall lineup" of chips.

(See: "AMD reclaims the high-end 3D card belt.")

AMD's recently introduced midrange and high-end graphics boards have been well-received and typically come at a discount to Nvidia boards that are roughly equal in performance. This forced Nvidia to cut prices on its performance graphics chips.

What does Nvidia think about AMD's new products? "Our competition has built a nice product but...the nice things that people write about their product is that it's well-priced," according to Huang, speaking during the earnings call.

Analysts confirm that AMD is making inroads. "(It's) pretty discernible. Certainly desktop standalone graphics, they've seen improvement there," said Dean McCarron, the principal and founder of Mercury Research, a company that tracks chip market movements. … Read more

While the jury is still debating the efficacy of Registry cleaners, Registry Repair from Glary seems to do its main job quickly and accurately. True to its name, the utility scans your PC's Registry, then fixes any errors it finds. Some of the extras are worth noting, too.

The app's main interface is easy to grasp at first sight, letting you check and uncheck boxes when deciding which portions of the Registry to scan. For instance, the program looks for such entries as obsolete software, invalid fonts, bad shortcuts, and even spyware. It's also handy that Registry … Read more

If you're going to be serious about electronics retail in the U.S., it looks like you have to be serious about employing professional geeks.

Beginning Saturday, 20 Sam's Club stores in Virginia and Maryland will offer tech support from PC repair services company Geeks on Call as part of a pilot program set to last three months. Sam's Club has 394 stores in the U.S. with several similar pilots running right now, according to a company spokesperson, who declined to elaborate.

Just last week, parent company Wal-Mart announced it would offer Dell-branded PC repair kiosks … Read more
