Specs: Windows 7, intel i7-4790K
I put together a PC and have had nothing but problems. Had to dish out $200 to a local PC repair place to figure out-- you know what anyway here's whats going on.

Installed Windows 7 64bit. Clean install, nothing else on hard drive.

It wouldn't even acknowledge that the LAN cable was in and the wireless network card wouldn't work either. Manually installed wireless drivers, now wireless recognizes internet but can't connect. I don't care about that yet.

Somehow or other the LAN cable thing, after doing the above drivers, could connect (even though the LAN cable port is on my motherboard and has nothing to do with the wireless card). So I was able to do Windows Update and download the Intel driver utility thing and start doing updates.

Now when I bootup I'm getting three main things as a problem.
1) Lan Cable isn't recognized every other bootup and I have to restart.
2) I'm getting a "Desktop WIndow Manager Stopped working and closed" error everytime I boot up
3) "WindowsUpdate_80240016" "WindowsUpdate_dt000" errors. Seems to not install the "Intel - Other Hardware - Intel Management Engine Interface" update.
4) Sometimes It seems like I'm getting 250kbs instead of 5MBPS
5)Some of the Intel updates won't install. "intel chipset device software inf update"

I own a small business and this was my video editing rig. I had finally gotten together enough money to upgrade my equipment and I was so excited for this. I spent $1600 on parts and couldn't get them to work. Spent another $200 on a repair place to 'diagnose' it. What was something I was happy and excited for is now a migraine and I'm at the end of my rope, I don't know what to do anymore and I'm almost beyond the point of caring now.

I'm going to copy/paste some stuff from Belarc to show what I've got incase it helps.

"It wouldn't even acknowledge that the LAN cable was in"
That's normal, until you install the drivers.

"now wireless recognizes internet but can't connect. I don't care about that yet"
Cable is faster & safer.

I use this on every comp that I work on, with driver problems.

Don't install any drivers, just upload SS ( screenshots ) of everything it finds & give us the links, please.

If you just built a new system you should have installed the motherboard drivers off the included CD. Going to 3rd party sites for drivers is the last resort.

1- Have someone experienced do a BIOS update, You have a Devil's Canyon CPU which was released just after the motherboard you have, to get full functions and less problems you need the latest BIOS update. I say get someone experienced because there is a risk when you do a BIOS update. The same if you are using some of the newer graphics cards.
2- Download all drivers from Gigabyte website for your motherboard and version of Windows. If needed, download on another machine and use a flash drive to transfer all over to the machine. Pay attention because I think that there are one or two that need to be installed before some of the others.
2a- Download graphics driver from graphics chipset mfg's site (NVidia, AMD, etc) only.
3- List exact makes and model numbers for all of your hardware, take from numbers boxes or invoices where possible. For better insights that will help you better.

Okay I used the existing drivers from the motherboard manufacturer (gigabyte). After fighting with this thing, somehow, it finally connected to the internet. The wireless still doesn't work even though those drivers are up to date.

I had to take it to a repair shop initially to diagnose why it wasn't coming on, apparently the processor pins on the motherboard were bent, and they bent them back and it allegedly works since I was able to install Windows and go through all the help and advice you all gave me.

But even after 250+ updates installed on Windows 7, the computer takes 6 1/2 minutes to boot up. I timed it. Literally six and a half minutes between the startup screen for windows and when the desktop pops up. It will pop up the 'desktop' almost immediately, but everything is black and blank. You still see the mouse and can move it around the screen, you can hit CTRL+ALT+DELETE and bring up task manager, but uh, nothing works until that 6 minutes has passed, then everything comes up like its fine.

Do you have an AntiVirus program running a scan at startup?

Go to Device Manager and see if there are any red or yellow punctuation marks by the hardware. Also look to see if there are multiple instances of the same device installed.

Boot into to BIOS screens and check the temperatures. Keep the computer running for at least five minutes while in the BIOS screens to see if the temperatures are high. Processor may be throttling down if that is the case.

Are you running the latest BIOS version.

How did you manage to bend the pins on the processor?

You still have not listed all of your hardware.
Did you go into BIOS set up and correct the setting for the CPU, SATA, Graphics, RAM, etc?
What hard drive are you running? Is it a SATA drive or an older drive? Is the SATA set in the BIOS to Legacy or AHCI?
What programs including antivirus program(s) are currently installed?
Have you performed a Windows Update Manually Yet??? Important!!!
There are many things you have not said or answered, without these answers we cannot properly diagnose your problems.

I haven't touched the BIOS, not really sure what I'd be looking for.

I have ZoneAlarm installed, it doesn't appear to be running a scan and that's never been a problem before on any other computer.

I have run Windows Update by pulling it up myself, I don't know if that's what you mean by manually. But if so, yeah there were 250+ updates.

PC stats/hardware screenshotted and listed in imgur album below.

BIOS data I haven't the faintest clue what you need to see but there's a lot here. I switched it to classic mode and took some pics

There have been a couple of BIOS updates since the F6 release.

One of them is for better compatibility with Intel generation 5 core processors:

This link is for Gigabytes Australian site but you can see the list of updates.

Remember that BIOS updates can be risky.

Installing the new BIOS update now. But, I just ran a real processor/graphics intensive program for about 20min to 30min and the temperature leapt up to 50° Celsius.

Sounds like your Thermal Paste may not have been applied properly.

Too much is as bad as not enough.

Check the manual, I think from the info you supplied that you have your two memory sticks on different memory channels, for best performance they should be on the same channel. I believe that is memory slots 1 & 3 or 2 & 4 which are the pairs.
I have to assume that you have a powerful enough power supply to power your system with the GTX970 graphics card. Is this correct?
The newest BIOS update will be an advantage in this case.
While 50C is not really high under strong load, checking/replacing the thermal compound - Carefully - may be a good idea. Make sure that you clean off all existing compound and apply it correctly.
The amount of Windows updates is about what I would expect from a new install of W7 today.
Your memory is running at 1333, is this correct or do you need to activate XMP Profile in BIOS for your memory to achieve its potential?
You have a Samsung EVO 850 which should be able to cold boot maybe 10 to 20 seconds or so. Are you sure that your SATA is set to AHCI?
