comment Did I just get hacked?
I used to work for a company that produced Linux based firewall boxes. Each one had remote support (SSH) disabled by default, and a unique SSH key and SSL certificate which we recorded during production right after the test stage. So yes, consumer boxes can be secure.

comment CPU and Memory Running Well Below Set Clock Speed
Double check your chosen power settings in Windows. Had a similar, rather hilarious situation with a MMO guild member's laptop doing this. He had accidentally left it in super-power-save mode from his last airline flight when he needed maximum battery life.

@AnkurTank: No, the question there seems well covered.

comment I need to repair SSD (RAW)
Sometimes this happens because the drive is dead and gone, and the controller is simply returning zeros to all reads. Best thing to do is to go back to your last backup.

comment Hard drive clicking for 16 times during startup
It certainly could be a power issue. I once ran into a "server" while doing some volunteer work whose hard drives trashed most of a track whenever a power brownout happened. I replaced the power supply with something better than a $20 "sparkle" and added a UPS and the hard drives were fine after that. A hard drive demands either 5V power or 0V power. 2V is right out.

comment How to transfer saved games from a Windows user profile to another user's profile?
Another place to look for game data is C:\ProgramData and / or C:\Users\All Users. I have seen some programs put all their data there and you pick the save file per user or per character. You can also delete/overwrite other user's save data.

comment How to extract a .dmg file in Linux?
It is a disk image. Unless someone has gone to all the work (which I guess 7z did) to write file system readers into their program, the easiest way is to use the Linux kernel filesystem modules to read the data. Which means mounting it.

comment When is too much voltage too much on a PC?
Where more precise values are needed the motherboard will have voltage regulators for each component that needs them, like the CPU and RAM. See also en.wikipedia.org/wiki/Voltage_regulator_module

comment Could a bad energy grid system cause a BSOD back in the year 2000?
A really good PSU in the computer saves you from most problems. The worst that can happen then is a power shutdown. However, a lot of desktops have bad PSUs made for $30 in a Chinese sweatshop and called Sunshine or something like that. Those don't protect you from anything.

comment What is the difference between BIOS and firmware?
Video-BIOS is from the days when BIOS loaded Option ROMS from peripherials into the BIOS. This is how the various BIOS video INT services are provided.

comment Are CPU clock ticks strictly periodic?
I have read that in multi-core CPUs the cores are also using offset clocks because it helps avoid radio noise, helps with power distribution, and avoids the cores building harmonics.

comment Should I disable swap file if I have lots of RAM or should I move it to a virtual RAM drive?
I agree that disabling swap can be a good idea. Anyone who's used Linux and had Evolution email run away with 3.5 GB of RAM would rather have Evo die than sit and wait for the laptop to stop swapping.

comment What's the difference between mobile and desktop processors?
@MattH: Having some well chosen extra instructions can help a lot. But NOT just "the instruction set is larger." After all, almost half the ISA in a modern Intel x86 chip isn't even used! Old compatibility instructions in 16 bit. Segment registers. An initial power-on sequence straight out of 1980.

comment File sizes in Windows not making sense
@FabricioAraujo: Traditionally we measured things in ounces, pounds, troy ounces, slugs, tons, stones, pinches, etc. And you had to know what you were measuring to know how big the unit was. Gold used different ounces from flour. Tradition is not a reason to do things the wrong way.

comment File sizes in Windows not making sense
@phyrfox: Mega is 1 million no matter what unit it applies to. This is the only thing that makes sense.
