I’m stuck with a Dell laptop that now fails to boot after just two weeks of normal use. I can accept the fact that I will probably fight with Dell technical support for six months before they do anything to help. What I can’t accept is that I can’t figure out what is wrong with this box.

Quite simply, using the laptop for an extended period results in incredibly slow performance, which leads to a lockup or blue screen, which leads to Windows no longer booting on the next cold restart. The ensuing error messages are varied and too numerous to list. After a clean install of Windows, every single diagnostic from the Dell CD comes back perfect. Memtest86 returns no errors.

I’ve swapped out hard drives and CD drives. But after two weeks, the result is exactly the same: no boot. I’ve tried other “unsupported operating systems” (read: Ubuntu), but they crash and burn just the same. If a Dell technician tells me to reinstall XP Home one more time, I may go postal!

I just completed a minor upgrade to my system, including the addition of a brand-spankin’-new Intel Core 2 Quad Q6600 CPU. My question: When you right-click a process in task manager it gives you the option to set affinity. If I’m right, this gives you the ability to set a process or task to a particular core of your CPU.

It seems like this would help distribute the load of everything running and keep things flowing smoothly, but it looks like every process is set to use all four cores.

Is there a right or wrong way to go about changing these settings? Is it advisable to change them? I would think that if you divided them up, you could gain a performance advantage.

Answer is after the jump!

How much antivirus and firewall protection do I need? I just purchased a laptop that comes with Norton Security 2007. I had also planned on using Webroot AntiVirus, which includes a firewall and anti-spyware protection. I also thought about using ThreatFire after I read about it in Maximum PC (February 2008), as well as Spybot Search & Destroy. Is all this overkill? What do you recommend?

I built an Intel-based system that’s running on a Gigabyte 945P-S3 motherboard. I’m chugging on three SATA hard drives—a 120GB, 250GB, and 500GB. The processor is a Core 2 Duo E6300 running at 1.86GHz, along with 4GB of 667MHz memory and a GeForce 5800 Ultra Extreme 512MB graphics card.

So what’s my problem? The system runs OK with 64-bit Vista Ultimate SP1, but I have a problem with the 500GB drive disappearing. It doesn’t show up in any of the installed diagnostic programs, Windows disk management, or anywhere else. If I swap the power supply connector around, the drive will show up for a while, but then it disappears again. (The power supply is a Thermaltake 800W unit that’s about a year old, and it has swappable plug connectors.)

 Most times a reboot shows the disk in the BIOS as “BzBzBzBz...” What’s going on?

Hey Doc,

I’m looking to build a desktop computer for home use. I want to go as wireless as possible—wireless keyboard and mouse, wireless headset, etc. The only thing that should be plugged in to my computer is, of course, the power supply. Do you know of any Intel Core 2 Duo chipset–based motherboards that feature built-in Wi-Fi for smooth wireless home computing?

Good question, Castlevaniaxx! Hit 'Read More' for the answer!
