comment Windows 8.1 mouse locked at 30fps on 60fps monitor
Also, are you using a wired or wireless network connection? Wireless network can interfere with the wireless mouse signal, see superuser.com/q/199348/29943

comment Windows 8.1 mouse locked at 30fps on 60fps monitor
For mice you have "position updates per second", not really frames. And for USB HID mice, the default is 125 per second, with gaming mice often configured for 1000 updates/second polling rate. Your wireless signal is quite possible the problem, can you borrow a wired USB mouse and see whether it moves more smoothly?

What video card are you using? What driver version?

comment Why do similar devices use a cross-over cable instead of a straight-through cable?
"Auto MDI-X was introduced in Gigabit ethernet" isn't accurate AFAIK. Gigabit makes it mandatory, but it was developed earlier (only some non-gigabit devices supported it)

comment Nvidia 9800 GT detects DVI monitor as VGA
You can't always tell them apart, a cable may be using the DVI-I connector but missing the wires corresponding to the analog pins; it would then be a DVI-D cable, but you'd need an ohmmeter to tell.

comment RAM tests inconsistently - what is the most likely culprit? (i.e. what should I spend money on replacing)
@brhans: It's not the timing parameters that matter, but the memory clock frequency, because the problem is in the transfer between the CPU and DIMMs, not internal to the DRAM. SPD usually has a number of profiles corresponding to different clock frequencies, choosing a different one of these would be better than going fully manual.

comment RAM tests inconsistently - what is the most likely culprit? (i.e. what should I spend money on replacing)
@bwDraco: Even though the memory controller is on the CPU, the motherboard also matters. The PCB layout can affect it, suboptimal length matching will decrease the phase margin on the signals (this is also why errors correlate to certain bytes or bit positions). That the motherboard manual doesn't talk about ranks doesn't mean that all combinations are supported, it just means it's a crap manual that doesn't go into detail.

@Michael: A bent pin would result in failures testing individual modules also.

comment how to go from windows 10 enterprise (unactivated) to windows 10 pro using windows 8.1 pro keys
The November update changed this, so that Windows 10 now accepts Windows 7 and 8 keys. See windows.microsoft.com/en-us/windows-10/activation-in-windows-10

comment Does Windows 10 File History protect against crypto malware
One of the insidious things about ransomware is that it can do significant damage, even without "running with permissions to touch every file on your computer".

comment What GPU does the Intel N3700 have?
@FrankThomas: That is providing the information. There's no undisclosed model number, this particular iGPU's model name doesn't have a number in it.

comment My laptop won't boot after adding RAM
Likely ubuntu is using a small fraction of the total memory, and just hasn't had the problem yet. Try a kernel compile.

comment Should I disable CPU fan error message and how?
Having a CPU fan spinning slowly (question indicated 500 RPM) and ready to immediately step up if the temperature increases is far far better than running the system with the cable disconnected. Passive cooling is possible, but you want a heatsink designed for that, and especially do not want unpowered fan blades sitting in the way of airflow.
