comment Windows 10 downgrade option missing, have windows.old directory
Interesting way of looking at things! I'll definitely give it a try. I do have Program Files both 64bit and 32 bit, Recovery, Users, Windows and Program Data directories saved in Windows.old

@Ramhound Why don't you post that as an answer??

comment Will adding more RAM speed up my computer?
@qasdfdsaq Keep in mind that all of that was written a bit less than 5 years ago, when things looked differently.

comment What information can my ISP see from my router?
@JakeGould That's how it's supposed to work, but in practice MAC address conflicts do appear, it's just that they are very hard to detect, unless it happens on computers which are on the same subnet. And then, you also have the "wild" manufacturers which use unregistered OUIs and have same MAC address on all (most?) of their products. This actually happened with some lab equipment that I have. Therefore I believe that your statement is a bit too optimistic.

@DragonLord Why would a gaming desktop, powered by a switch-mode power supply, require a "sine-wave" input?

comment How to determine what's trying to access my optical drive (emits unusual sounds)?
Unfortunately, none of the offered programs were helpful. When the drive emits sounds and there's no disk in the drive, Process Monitor shows nothing. During the past few days, the drive spun up with a disk in it only once, but I was unable to start Process Monitor quickly enough to catch the event.

The sound is the same as when optical drive is initializing. In my case, I have a laptop, and the connection between the drive and motherboard is a solid PCB. I've checked it and it looks good. I've heard reports of other users of same model of computer with different optical drive having same issue.

@UltraDEVV It's a good idea to try with another OS. About the brand, well I don't see what the big problem is. Perhaps it's a more local thing, but in my circles Toshiba has good reputation, and Samsung has 0% market share penetration in laptops. Local issues maybe?

comment I broke the USB port on my external HDD. What do I do?
There are two ways you can go to fix this: The simple way and the complicated way. The HDD is a SATA HDD, so you can just disconnect the disk itself, find a desktop computer or another enclosure and insert it there. The more complicated way would be to repair the USB connector itself. To me, it looks repairable, but to be sure, I'd need better picture of the connector's footprint on the PCB, especially near the part marked P2 and of the back side of the connector itself.

comment How many watts do case fans generally use?
@Cees Timmerman Indeed! That's 18 W per fan. Multiple fans and optimistically rated power supply can produce very interesting results, especially of the rest of the computer is hungry as well.

comment I have to cycle my LCD monitor's power on and off to get it to stay on
@Sampo Sarrala Anyway, my point is that learning how to solder just in order to save money on capacitor repair is false economy. On the other hand, if someone is already in electronics, then it's not as problematic because the basic foundations will already be there.

@Sampo Sarrala Then we have the problem of iron being fit for the job of working with the capacitor: Too powerful and non-temperature controlled as well as too weak can result in damaged PCB. Next, there's the knowledge needed to pick and install a replacement capacitor. Again, getting a capacitor from eBay or similar source can be problematic and it takes some experience to find a reliable distributor of safe capacitors.

@Sampo Sarrala I wholeheartedly disagree with such comment. I don't think it's safe for someone who doesn't already have experience using soldering iron to attempt to replace capacitors. First problem is the iron itself. A beginner won't be able to see difference between dx.com junk that will catch on fire and dx.com junk that won't catch on fire. Next, there's some training that's needed in order to be able to actually desolder a capacitor from a PCB without damaging the PCB itself. Lifted traces aren't going to make repair any easier.

Looks like this was it. I just wasn't paranoid enough with the flash drive.

Yeah, it's been so long since I used a public computer that I completely forgot about possibility of malware running on it.

comment Is there a limit to how many separate wifi networks can successfully and securely operate within a given (building) area without interference issues?
This takes care of interference problems, since in such setups lightweight access points would be aware of eachothers's signal and using the control point can be adjusted to reduce their own transmit power so that the interference is minimized. If you have a large area which you yourself can administer, that can work well. If you can use 5 GHz, it can work even better due to larger number of channels and worse propagation on that band resulting in less interference.

What I've seen used the most in such setups and with most success is the use of sort of light weight access points that are connected together over wired Ethernet. They are then connected to a central controller from which the network can be administered. In the older systems, you'd place a hexagonal honeycomb-like structure over the floor-plan and then set a frequency and power for each cell, so that adjacent cells have different frequencies. Today, smarter systems can do that on their own.
