The first place to start tweaking is your BIOS. Enter your BIOS by hitting a key combination on system boot (look out for F1, Del etc). A word of warning though, the BIOS is a very powerful tool, but can cause damage if pushed the wrong way.

Finding a good PC or notebook for the family is not as hard as you might think. PC Authority  puts the latest models to the test.

Since the launch of PC Authority magazine 30 issues ago, we have placed an emphasis on the concept of computing in the real world. This means that all the PC hardware that passes through our Labs is t

Evaluating barebones systems is quite different from performance-based testing using benchmarks. As such, we opted to do a feature-based roundup, covering all aspects of the hardware, including but not limited to: build quality, ease of install, and included feature sets.

We know you want to play games, so we've put 18 PCI Express graphics cards under the microscope to see who really does the job the best.

We put every current model from ATI and NVIDIA through its paces to find out which offers the best performance and value.

Benchmarking PCs is a tricky business. You need to ensure that you stress the systems, but also that the results you get will be relevant in the real world. Previously we have relied heavily on BAPCo's SYSmark2002 for simulating home and office use, with programs such as Excel, Word, Outlook, and web content through Adobe Premiere and Macromedia Dreamweaver. However, due to SYSmark's history of instability as well as the sheer length of time it takes to complete a run, we have put it on the backburner in favour of PCMark04 for this Labs.

Not long ago both Intel and the underdog, AMD, battled to reach the coveted and psychologically significant 1GHz mark. When the AMD Athlon reached the landmark first - it marked a new era in c

We've taken seven top business PCs and run them through their paces to find out which should be your next upgrade.

While hard disk drive speed is commonly one of the last considerations when putting together a new machine, its importance is more than just a place to store your files and operating system.

The notebooks were subjected to several benchmarks to give an objective evaluation of their speeds, performance and applicability.

Unlike many of our performance-based Labs, business workstations are a whole different world of PCs, focusing not on the maximum number of frames per second, or how many overall points they can churn out in any given benchmarking utility.

This Labs featured in the March 2000 issue, any pricing seen in these reviews were correct at the time of printing.

We put six sub-$500 pocketable cameras to the test

Testing anti-virus software is a tricky endeavour at the best of times, due to the inherent nasty nature of the test subject. For this anti-virus roundup, we asked independent anti-virus testing lab, AV-Test.org (www.av-test.org) to conduct the testing for us in their controlled environments. AV-Test.org has access to thousands of viruses, and is a respected anti-virus testing lab.

If you equate the CPU as the brains of the PC then think of the motherboard as the nervous system, shuffling signals back and forth from the extremities of your PC. In exposing these 15 e

DDR (Double Data Rate) RAM is a relative newcomer to the PC as system memory, although it is certainly not a fledgling technology. Graphics cards, and other components that require much higher memory

Small form factor PCs have been around for a while, and barebones PCs for even longer. Traditionally a barebones PC is a basic shell, including a case, power supply and motherboard at minimum, and occasionally tooled up with a few extras like RAM.

The Labs team always likes a good Christmas PC roundup. It gives us a chance to down the callipers, and off the lab coats for a short time, and really experience the fun side of PC technology. And thi
