How much power the system is REALLY consuming? I suspect that my ATX case's power unit from China provides FAR LESS power than it's supposed to. Is there a way to see (in real time) how much power the whole system is trying to consume and how much is it really getting? Maybe, not in watts, but the voltage is not enough, say, 4.5V instead of 5V. What I ...

How to find and remove "spicy" media files from my PC I think that this is worthy of question of the week: It is probably a question a lot of people have. It has sparked a lot of interesting conversation about cleaning out files from hard drives (especially if you don't know what they're called and you can't just format the whole thing). I think it could ...

What are some options for transfering large files without using the Internet? My employer's Internet connection is extremely slow. It's a $6,000 a month, 9 Mb, bonded T1, shared by over 150 users. It's not untypical to see regular file transfer speeds of 20-100 KBps. [...] When I need to download a large file (which is frequently), I drive 40 ...

Why does Windows Progress Bar always give such horrible estimates? I realized this "bug" a long time ago, since Windows 95/98, but it still continues until today, on Windows Seven... The displayed remainder time was on 60 minutes, but the real time was less than 2 minutes.

How to store and preserve lots of data? I have many DVDs with movies and games, they are getting old and dusty, some of them are damaged. And I have more than 300 GB of general files in my PC. I want to store and preserve all of my data and keep them for a long long time.

Is it possible to use a storage disk (such as a USB drive) as RAM? My motherboard (HP Pavilion s3000y) only supports 2GB of RAM max. Which means that I can only allocate 1GB for running VMs, and applications that use a lot of RAM are slow (such as games and Visual Studio). Is it possible to use a storage disk such as a USB drive as RAM?

I like this one, because it's a good learning opportunity for people and applies to a broad audience. I'd also be interested in learning more about how this law applies to website owners outside of the EU. Why are websites suddenly asking me about cookies? (The answer relates to a new law in the EU regarding privacy and tracking)

Why are websites suddenly asking me about cookies? I have for a long time known that websites give me cookies so that small pieces of information can be remembered about my habits, passwords etc. I accept this, but all of a sudden they are asking for my permission to do so. Why has this changed? What sparked this?

I found that quite interesting: How do I hit the CTRL key without straining my pinky? When I'm using Chrome, Powerpoint, Notepad++, etc. I take a lot of advantage of the keyboard shortcuts in those programs. However, this gets a bit tedious and straining, having my pinky stretch down to the CTRL key every time I need to save, for example. [...] ...

What is the purpose of the holes marked "Do Not Cover" on hard drives? On many hard drives, there's a text warning to "not cover this hole", sometimes adding that doing so will void the warranty. What is the purpose of this hole and why would it cause damage or increase the likelihood of drive failure?

Why does an 8 GB and 16 GB USB drive have the same physical size but a different amount of storage? This question has turned up some interesting stuff about how memory chips are manufactured. Might make for a good blog post.

Why is my dual-core CPU recognized as a quad-core one? Interesting discussion about how hyperthreaded CPUs are recognized as having twice as many cores as they actually do.

I found this one quite interesting: 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). ...

Liked this Remotely turning on or rebooting a frozen computer I use a remote desktop program (usually Microsoft's Remote Desktop) to connect to a Windows machine everyday. The remote computer has a fixed IP address, and if the computer is on and responsive, I can reboot the computer remotely to install updates, etc., as well as turn it off. ...

My current favourite is this one. It's new, but it's a good question with some great answers that teach you a bit about how processors, or rather programmers, handle operations that don't fit inside a registers width. How can a computer calculate exponential maths without overflow error? I find the "fit inside a register" to be an important part because ...

How much information can websites get about your browser/PC? Does anyone know of any other sites that will be able to get more information from the user passively like this? I'm not talking about port-sniffing or any kind of interaction from the user, just the info that a server can get from a 'dumb' visit.

Is the Windows Experience Index calculation the same on Windows 7 and 8 Is the Windows Experience Index score calculated the same way on Windows 7 and 8?

Due to it having been a QOTW, I've undeleted it and locked the post for historical significance. It's not really a particularly on-topic question, but I think in this edge case it should be kept, for that reason.

What's the use of windows hard disk write cache when the hard drive already has more than 8 megabytes of cache? Doesn't a hard drive use its cache with high utilization? I see up to 20MB/s difference on file writes when I disable windows disk write cache. Does anybody know why cache size matters this much?

From last week via @Sathya: How much information can websites get about your browser/PC?

How does Windows detect battery issues? I have a laptop that's a little over 5 years old, and I've never changed the battery, so I believe Windows 7 when it tells me "there is a problem with your battery", and to consider replacing it. My question is: how does it detect a dodgy battery? Does the battery not have the same voltage that it used to? I ...

How to know if your computer is hit by a dnschanger virus? Perhaps could append how the computer got infected as well. Pro: Get to understand how a virus affects your computer. Preparing people for when a future attempt occurs. Con: Servers took down, might no longer be relevant / valuable. Might be more Security.SE material.

Why does the expression exp(i*pi) return the wrong result in GNU Octave? I started to learn GNU Octave today, and tried the first expression given in the manual: exp(i*pi) The result is: ans = -1.0000e+000 + 1.2246e-016i And it seems GNU Scientific Library gives similar results too. So is this a Octave bug, or general problems of numeric ...

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 A lot of people probably wonder this: do I really need to download all 50 updates? My precious bandwidth! Ranon's answer goes into some good ...

Does "Stopping" USB drives actually affect the drive? A great answer with a little-known option of how Windows handles external drives.

Does a computer use fewer resources when programs are minimized? When programs are minimized in Windows 7, do they use less memory and CPU than leaving them maximized?

How to find the process(es) which are hogging the machine I thought it was a really cool question, and one that would be handy to know. If I were to write about it, I would be doing testing on Windows.

Can AVI files contain a virus? Some people might not be aware of this, as well as sites that want you to dowload codecs; awareness of this is pretty crucial, which is why I think this could also make up for a good QotW. Many people assume such containers are safe, but it's never too late for a zero-day exploit.

I've thought about doing a Review/How-To-Use of Hyper-V in Windows 8. I asked & answered this question: How do I install and use Windows Virtual PC in Windows 8? And found/answered this one as well: Windows 8 Hyper-V - how to give VM internet access? There are a few other features that I can go into detail like: Overview of Snapshots Requirements ...
