Might seem silly but make sure the switch on the PSU is on.

I think Microsoft said if you swap the CPU your Windows deactivates. Kinguin offers some cheap ($20 USD) Windows Keys

Well, the only thing left to do that I can think of is to contact your internet service provider and tell them about your problem. Hope you can get bragging rights about low ping soon!

Well if the problem only recently started then Cat6 cables probably won't help, unless the current cables are damaged in some way. There's no need to rush out and buy a cat6 cable though, just if you had one it would be nice. Have you tried plugging your ethernet cable into the modem instead of the router?

I wouldn't ask "why not 4GB or above" because OP was asking a question and looking for help. Sure, I might recommend him some 4GB sticks of RAM that might be better, but i'm still going to answer the question as best I can. Just asking "why not more RAM" could waste the questioners time. tl;dr answer OP's question first, then recommend what you think is best.

Because OP said they needed a TV for his room, not a monitor. Not to pick sides between this fight but OP just said they needed a TV.

I'd say the Samsung one looks better on paper and on reviews. I would also go for the Samsung one just because I have one of their phones but hey, i'm not you.

Cereal5 is right about the 2 expansion slots. To be more specific, Amazon says the 1080 Founders Edition is 1.5(w) x 10.5(l) x 4.38(h) inches.

I would assume so. There were some problems reported for macOS El Capitan doing a quick Google search, but I would go ahead and guess that they fixed that as I don't see any problems for WD drives with Sierra. Just make sure you have all the WD software and drivers installed before installing the drive itself.

I second Aytex, except I don't know about the D5 model's benefits over the windforce OC's and I would buy a Windows key from Kinguin instead, but that's just preference.

The recommended wattage using the website itself is 417, so a 550 watt power supply should do, but any future upgrades to the PC would be minimal.

Here's a pretty cheap one: https://www.amazon.com/dp/B001CCGYU0/?tag=pcpapi-20 That said if you want a quality one for under $30 USD: https://www.amazon.com/Cooler-Master-Hyper-212-RR-212E-20PK-R2/dp/B005O65JXI/

Modem firmware update? Faulty ethernet cable? TYPE of cable? (cat 6, hopefully) When my internet doesn't work AT ALL, I unscrew the coaxial cable in the back, wait a couple minutes, then screw it back in. I have the Xfinity Router/Modem combo that looks like this.
