Why isn't 255.255.249.0 a valid subnet mask?
It's not a valid subnet mask because it doesn't define a prefix. If you convert it to binary, you'll see that its '1'-bits (and/or its '0'-bits) are not all contiguous. This is explicitly forbidden by ...

Computer turns on but no signal in monitor
I believe your problem is that you bought an "AMD Athlon X4 860K" processor expecting it to have integrated graphics, however it does not. As you have listed your parts, there is no GPU in your part ...

Why isn't 255.255.249.0 a valid subnet mask?
The mask needs to contiguously have high order bits on to mask the network address under which the subnet addresses are. 249 does not have this property, as it is 11111001 in binary, there are zeroes ...

Does an extra old internal hard disk drive affect my new PC system’s performance?
Possibly.
From a Hardware Standpoint: It shouldn't, but this may depend on the SATA chip on the motherboard. Having to read large quantities of information through a slow channel might adversely ...

If I remove the Luks-encrypted drive to another motherboard, will I be able to run my system there?
The motherboard doesn't do the encryption; the OS does, entirely in software. The volume can be unlocked for as long as you remember the passphrase.
An exception is when you use TPM to implement ...

why does my wifi think my desktop is 10 different devices and why does each one have a different ip address?
Well, if you're running modern OSes, windows included, they have an option for randomised MAC addresses as a privacy option. Since many routers are going to give a different IP per mac address, its ...
