Ok, I googled the issue, and someone said they had some luck with disabling the USB 3.0 ports in bios, and turning them back on again. I tried it, and it seemed to work. So, USB 3.0 is working again. The only thing I can attribute the wireless dongle to having low internet speeds is that it is a driver issue, and I might need to uninstall and reinstall drivers. I don't mind doing this, I just need to know how to do this and not bork my computer.
Rear USB 3.0 ports are blue. Front are hooked into the motherboard USB 3.0 port. I just did a speed test of sorts, and a 1.5GB file transferred in a matter of seconds to a USB 3.0 portable hard drive. I did the reverse to make sure that upload and download speed to and from the portable hard drive were at 3.0 speeds, and they were.
I will open a new ticket for uninstalling and reinstalling all of my drivers if you want me to (or whatever you think I should do). I'd rather just do it here and be done with it though. We've been going at this for what, three weeks now? That's not to say I don't appreciate all of the time you've put into helping me, I'm just ready to be done with it.
I do owe you a major thank you for helping me so far. So thank you, thank you very much for all of your kind help.
So..... in spite of computers either hating me, or a divine comedy of sorts, I have figured out the problem. My motherboard came with Live Updater 6 which I installed to help keep my drivers up to date. Simple enough. What I didn't know is that the two driver options available for my network adapter contained a driver that was bare-bones or severely out of date, and a driver that made my internet zoom. The first was the driver only and labeled as such on the download options, and the second was for the Killer Network Utility + Driver. I guess it needed that utility to go really fast. Sorry for wasting your time on that at all.
I would still like to know what the heck went wrong on my original motherboard and power supply, which one failed, and what I can do to prevent that in the future, but if you want to call this closed, I completely understand. I will be ordering that power supply you recommended in the near future, unless you can think of a better option. Power supplies are not my forte.
Again, thank you so much for all of your help and patience during this. I really do appreciate it. Thank you.
