comment What do you put in your computer repair toolkit?
It is hard to say how often you'd use it, but it can be invaluable in diagnosing a hardware problem.

comment CPU temperature vs. CPU Heatsink Temperature
This is actually incorrect. There are temperature sensors in current processors. Current processors provide access via a 1-wire or 2-wire interface. Older generation processors have a thermal diode which can be read by a remote temperature sensor. This is on top of the overtemp signals (of which there are two -- an approaching max threshold and have exceeded max threshold).

comment How can I identify the weak link in my system's cooling?
Thermal paste is a common cause of processors heating up when the heatsink appears to be working fine. I wouldn't worry about the -12V signal because it probably isn't even used in a current motherboard. I also wouldn't trust the software reading. A meter is much more accurate and you can probe around to see what the different voltages is across the board (there will be a drop from the source to the load if any current is being drawn).

comment Is a system fan crucial to a computer if you already have a CPU fan?
Most newer processor fans are 4 wire. 3 wire is still the most common outside of the processor fan. The system fan may still be running just the TACH isn't hooked to the expected header.

comment Server works with either ECC or non-ECC ram but not both (manual requires unbuffered)?
99% sure it is unbuffered. Registered memory is keyed differently.

Yup, you just need a BIOS update if an AM2+ doesn't work in an AM2 socket.

comment Voltage goes up when using dual graphics cards
Just curious, where are you measuring the voltage? Voltage is highest at the source (power plug) and lowest at the destination (load).

comment Voltage goes up when using dual graphics cards
+1 Definitely sounds like a power-to-power short. Need to make sure cards are seated properly and aren't touching anything conductive.

comment Can I build or test a computer without a case?
Modern processors typically do require a thermal solution that screws into something. That kit looks interesting. In the past, I'd just wired up the switches myself (but I have a fully stocked electronics lab at work).

comment Are USB cables device specific?
Ferrite Beads are more for EMC/EMI and act as high frequency filters to reduce noise that could radiate from the cable. It doesn't affect compatibility.

comment Power supply issue? New Radeon5850's fan runs at full speed and PC doesn't boot
The User Manual states in the Technology Features that it has "Dual +12 V Rails." That could be inaccurate, though. I don't have any intimate knowledge of the design of this specific power supply.

comment Vista freezing randomly at startup
If safe mode also failed, then drivers as the problem would be ruled out for the most part. But since it passes, drivers could still be the issue.

comment Why does the fan in my desktop tower run so high when monitors are disabled?
Fan control can vary depending upon the motherboard design. My understanding (as a motherboard hardware designer) is that it usually resides in the BIOS tells the OS using an ACPI interface. One way to override is covered in the question superuser.com/questions/29049/… Fan control can also run autonomously via SMBus, Super I/O or Application Specific IC devices based on temperature reading(s).

comment 3 wire computer fan won't run continuously
Good catch, he was trying to power it by a 9V battery, so the wires are most likely exposed.

comment 3 wire computer fan won't run continuously
Yikes! A 3-pin fan plugs into a 4-pin fan header no problem. A 4-pin fan header has the shroud on once side of 3-pins only, this is so the 3-pin fan header can plug right in and have the correct orientation. No splicing needed, but you won't get any fan control either.
