comment I'm getting repetitive left click in java applications
@Karan The problem seems to start after first mouse-click in the Java application. Also just in case my mouse decided it hates Java, I did try with another mouse and touchpad and they seem to hate it too :).

comment Why aren't there PCIe RAM expansions?
Note: Almost no PC have PCI-X. It was only found in server market and tops out at around 1 GB/s. Furthermore it's obsolete. It was development based on classical PCI and is not related to PCI Express (often abbreviated PCIe).

comment How suitable might my loft/attic be to install a network router and switch?
@Neil Barnwell Do note that although routers have processors that heat up less, they usually have little or no cooling provisions. For example, my room temperature is right now 23.3 C and the temperature inside my router is 43.1 C. Temperature of the system on a chip will be even higher than that and it could easily go uncomfortably high in the summer.

comment Why won't my Nokia E52 charge on some USB ports
@Juha Untinen Combined with high resistance of the cable (which can be surprisingly high! I've had cases of as much as 0.7 V drop on a USB cable), it could result in a voltage that is too low for the phone to start charging.

comment Why won't my Nokia E52 charge on some USB ports
@Juha Untinen After experimenting with USB ports on laptops (which often provide voltages on the bottom part of acceptable range) and thin cables often used for USB A to micro USB B cables (and I guess many small proprietary connectors), the only only thing that comes to my mind that could explain the behavior is that for some reason, there is a small difference in output voltages between USB ports under load.

comment Sharing LAN between two buildings. What should I use?
@David Schwartz I agree. It really does look like a good representative of what would be needed. That particular unit does however use proprietary Power over Ethernet (which might be a problem) and comments say that it doesn't support VLAN tagging.

comment Sharing LAN between two buildings. What should I use?
About the edit: Why would that make network unstable any more than a single cable? Also what do you consider "stable"? Good cable can easily run for rated distance and there shouldn't be many (usually any) physical layer problems int the cable itself. It's the WiFi part that can be problematic due to weather and interference from other sources (which is why I recommended 5 GHz, since it's usually less crowded, unless you're near radars).

In any case it should be kept in mind that Wifi is still half-duplex and despite higher nominal speed will be slower in practice than Fast Ethernet.

comment Sharing LAN between two buildings. What should I use?
This is a really outdated answer. Today for higher speeds much better option would be to use IEEE 802.11n equipment, preferably in the 5 GHz spectrum using 2:2x2 or better antenna configuration. Directional antennas would be a bonus. As mentioned, for even more cost savings, two good routers could be set up using free firmwares to work as a bridge. Speeds in from 150 Mb/s to 450 Mb/s could be obtained this way, although 450 Mb/s eqipment is a bit harder to obtain and more expensive than 300 Mb/s equipment.

@Mark Johnson Don't worry, I've already made arrangements in case something happens. Report will be made.

@Mark Johnson Yes and? More technically minded people there don't know it either or at least didn't when I posted the question.

comment How can I figure out which PC component is faulty when the PC won't even start?
The description to me looks like a short-circuit somewhere. PSU starts, detects overload and shuts down. After that it waits a while and tries to start again. Check if any solder joints are touching the case or if there are any loose components in the computer.

comment Getting BSODs when video card load is LOW
Looks like everything is already set to high power and maximum performance (PowerMizer is set not to manage and in manage 3D settings, power management mode is at max performance). Eveything is at max performance in Windows power optios too, except for display turn off timer. One thing I did notice is that when at full power, GPU-Z reports 1.05 V and before running any significant load, it's 0.85 V. This could be significant, but at the moment, I don't know how to affect that.

@TheUser1024 Good idea. I'll take a look.

comment Force application to run in 32-bit process on 64-bit Windows
@William C I don't think there's much you can do in that case except maybe messing with compatibility settings. For the example I was talking about, you'd literary have loader.exe (or something similar) which is first started and it chooses whether to run the 32bit or 64 bit exe. Usually you can run the executable itself instead of the loader.

comment CPU running at full capacity when boot to DOS?
Actually, I used a thermocouple attached to the heatsink and a fan connected to a constant voltage source (so any motherboard interference is eliminated) for temperature measurements.

comment IP Helper Virus?
+1 My guess here would be that something is causing problems with IPv6 Internet connection and the computer is waiting for connection attempts to timeout before trying to use IPv4.
