My First PC Building Experience (Part 3)

January 27, 2012 by . 8 comments

Click here to read part 2.

Well, this is the final post in this 3-parter!

In the previous picture at the end of part 2, there are a couple of clearly visible mistakes in cabling that I didn’t notice at the time. I didn’t notice them because they weren’t the type of mistakes that cause breakage, but just were unnecessary. The first was that I used both Crossfire bridges with the graphics cards. Only one gets used between two cards anyway, so I was able to remove one of them (the second one is if was going to hook up a third graphics card). The second mistake was that I ran a PCI-e power cable to the motherboard’s PCI-e power connection. This power connection is useful if the PCI-e cards don’t have external power and aren’t getting enough power from the PCI-e rails as it is. But since my graphics cards do already draw external power,

My First PC Building Experience (Part 2)

January 23, 2012 by . 0 comments

Click here to read part 1.

So, at this point, I had a usable computer. Since I was pretty burned out by the hours I spent working on it already, I didn’t want to dive right back in and started using it a bit more. Besides, I didn’t know I wasn’t done yet (aside from knowing I was missing a multi-card reader, which I need). There was also the fact that the hard drive cage was laying out on the floor and it was somewhat annoying. But that was stuff I was willing to deal with in the short term, as I wanted to get working on setting up the software in my newly built PC. After using it for a few days and discussing the project with friends and coworkers, I started thinking about things I could do to improve it.

My First PC Building Experience (Part 1)

January 18, 2012 by . 3 comments

So, earlier this year I decided that I would build a PC for the first time. Previously, I had only done component upgrades on prebuilt computers. This got me familiar with working inside a computer case, but I never had built one from scratch, so I had to figure out what is involved with choosing components, matching things together to make sure everything is compatible, and what it’s like to do all the subsequent tweaking and troubleshooting when the inevitable problems arise.

Making the Ultimate All-In-One Installation Flash Drive

December 22, 2011 by . 3 comments

Super Users often find ourselves installing operating systems. Whether you run your own computer shop, manage an army of thousands of corporate workstations, or are just the tech-savvy friend everyone you know calls for help, you’ve probably had to install various flavors of Windows over and over again. Most of us have also spent a fair amount of time installing different Linux distros, running data recovery disks, and using various live CDs.

The problem that presents itself is managing all of the required disks. There are at least 6 common flavors of Windows 7 alone (Home Premium, Professional, and Ultimate for both x86 and x64, plus Enterprise for you corporate types). Add in various distros of Linux and you start to see why some computer techs carry around whole folders of CDs.

I’ve been aware of Pendrive Linux for a while, which lets you setup a flash drive with multiboot Linux software, and can add a single Windows installation. But what if you wanted to have a single flash drive with all versions of Windows 7, as well as all the standard Linux boot disks? It took some work, but I decided to do this and the final result is impressive.

WWWhat’s in a Name?

December 15, 2011 by . 7 comments

A recent question asked:

What does wwws mean? Is it to do with Security?

I’ve seen a couple of sites that use wwws in their domain, for example: and I’m sure it has something to do with an extra layer of security. What does it mean and what is it used for? Why do only a handful of sites use it?

Some Updates to the FAQ

December 12, 2011 by . 0 comments

The next time you’re taking a look at our Frequently Asked Questions list, you may notice some small changes:


A few months ago, we had some discussion on meta about whether home networking questions were within the scope of Super User. The community proposed via Super User Meta that we update the FAQ to more directly represent that home networking questions are allowed on Super User, and always have been – it just hadn’t been specifically mentioned in the FAQ.

In the course of this discussion, it was also agreed that we should include a statement to the effect of questions dealing with corporate networks and support being off-topic, as they are more appropriate for Server Fault.

After some editing and discussion, the following changes were decided upon:

  • Adding to the “If you have a question about” section: personal and home computer networking
  • Adding to the “question is not about” section: issues specific to corporate IT support and networks

Please note that these changes to the FAQ do not represent a change in policy for Super User — questions which were previously on-topic are still on-topic. We just changed the language to make the site’s policies more explicit.

Several people have already asked about the distinction of professional IT support and corporate networking. Increasingly, the line between “business” and “consumer” computers is blurring. Indeed, the definition of what constitutes a computer is itself a topic of debate.

To clarify: any question where the answer would be essentially the same whether you asked it about your workplace computer or home computer is perfectly valid on Super User. Data recovery, installing operating systems, connecting between computers, and so forth are all still welcome. The types of IT questions we discourage are things like volume licensing, active directory, business-grade routers, mass image deployment, and other issues which are irrelevant to non-corporate users. These are the sorts of thing we mean by “issues specific to corporate IT support”.

If you have any further questions, feel free to leave them in the comments on this post, and the Super User moderation team will respond to your queries. You can also reach us in the Ask a Moderator Chat Room.

Virtualization – Why the Hype?

November 9, 2011 by . 3 comments

It’s time for our Question of the Week. This time, Jacob Hayden asked:

Why is there so much hype about Virtualization these days?

Virtual machine, Virtual server, Virtual disk, etc…… It doesn’t make much sense to me why someone would want to make their things “virtual” when basically that adds another layer to everything (which in most cases will make it run more slow). What’s the purpose of Virtualization in the multiple cases above?

While this sounds like a very subjective question, it gained quite some attention. Our long-term user William Hilsum added a great answer, explaining what virtualization even is, and how it became so useful these days.

October 31, 2011 by . 2 comments

We return with a new Question of the Week, this time addressing Windows Updates. Lital maatuk asks,

Which of the Windows updates are really necessary?

I downloaded a lot of Windows updates in the automatic mode. Are they all necessary? Can I remove some of them? How do I know which ones are necessary?

Jens Erat, one of our newest users, gave a very detailed and well thought-out answer about the different types of Windows updates and their relative importance.
