So to fully get to my point, I'm going to have to explain everything that has happened prior to my networking trouble within the last 10 hours of this post.

About 9 months about I had installed a custom bootskin/startup splash screen for when I started my computer. Recently I enabled "Super Admin" and transferred all my stuff from my old user to it. For some reason, the bootskin failed to load after that, and started using what looked like a standard splash loader you might see on like Windows 98. No issues other than that.

I decided early this morning though that I wanted to go ahead and just change it back to the standard Windows 7 splash screen. That was the worst mistake I could have made.

I instantly was forced into a looping startup repair. Having been through a similar, unrelated issue, I put in my windows disk and used the bootrec command prompts, which wasn't working, eventually getting me the "Error 0xc000428" about the boot loader having an invalid signature. Eventually, reactivating the partition and letting startup repair run about 3 times fixed it, setting the loader back to the little windows 98 splash and booting to my desktop. However, none of my network adapter will connect to the internet, bringing me to my current issue.

They don't even connect to the router via ethernet cable. I've tried many of the ipconfig commands trying to diagnose the issue. Running troubleshoot gets me ' "Local Area Connection" doesn't have a valid IP Configuration ' Setting preferred IP configs and DNS setting either gives me the "Cannot contact DNS Server" or doesn't read any issues at all, yet I'm still not connected. I'm frustrated and guilt tripping myself for doing something risky, knowing I have things to do that need the internet. I'm hoping someone can give me a hand. I'll be as patient as I can and give any logs needed.

My OS System is Windows 7 Ultimate 32 bit

Thank you.

At this point, i would try a clean install honestly. You can lose a lot of time trying to figure out a way to fix it. I think you have already spent enough time on this and you probably need to use your computer. Try a clean install and let us know! Sorry i couldnt be more helpful

First, try to reinstall the LAN drivers on the motherboard and the drivers for the wireless adapter.

Next, Check if windows firewall has not blocked the user or the network,
Or
for the sake of testing, temporarily disable the firewall on windows and anti virus.

@boosted1g I just tried that. It didn't work I'm afraid.

@plaintuts: The ethernet adapter is the onboard motherboard ethernet, I'm not using wireless and firewalls have been off.

@bjsm: lol, dude you have no idea how many times.

I don't need to run it on administrator because I'm using the system Administrator as my account so it works either way. How would I access the router interface? You mean from 192.168.1.1 here on my laptop? (that's what I've been using for this by the way. My desktop is the pc with the issues)

Uhmm.. Please try to run cmd on administrator. By right-clicking the program then select run as administrator, then try ip flush and netsh..
(the explanation for this is kinda long, as to why but, please try it)

You will need to connect the laptop thru the ethernet cable to access the router.
And yes, thats probably the router address

It's not, strangely enough it follows the DHCP from the router as 192.168.1.7 My desktop didn't and I had to set it manually under the adapter settings to 192.168.1.20. Yet this still didn't work of course.

Well the IP stayed, but I don't think it's getting connectivity from the router at all. There are not IP conflict, the router says my laptop is connect while it doesn't read my desktop, and my desktop still has no connection to anything what so ever.

Correct. The laptop is set to automatic but its gateway is set to 192.168.1.1. I've tried setting the gateway of the desktop to the same however troubleshoot can't detect issues. Also, when I apply settings for the ipv4 on the desktop, I get a notice saying "Warning - The default gateway is not on the same network segment (subnet) that is defined by the IP address and Subnet Mask. Do you want to save this configuration?"

Changing the Desktops gateway to 192.168.1.1 lets it be recognized by windows as "Network 2" which was the normal name it was picked up as, instead of unidentified. Still no connectivity.

I would try disabling the ipv6 protocol in the setting of the adapter(wired or wireless), then setting the ipv4 correctly, and putting everything to default. Then reboot router modem etc, try again and let us know what your ipconfig /all is and make sure you ipconfig /flushdns. I hope this makes sense, because you have done so many manipulations at this points that its getting harder to tell.
