Microphone isn't picking up my voice properly

For some crazy unknown reason, my mic isn't properly picking up my voice.

My headset is the Razer Carcharias http://www.razerzone.com/store/razer-carcharias-for-xbox-pc

(the link I provided is actually some newer version of what I have. Mine isn't for the XBox, just PC. The controller node thing in the middle of the chord is different, not that it makes much of a difference.)

I feel like I've done every single possible troubleshoot that is possible, and I still can't find the problem.

My mic is being picked up and recognized, but when I talk, it doesn't pick up sound unless I put my mouth right up against the microphone.

Here is everything that I've tried, and I will also provide screenshots of what I can show you:

I checked to make sure it wasn't muted on the chord string thing (the little switch).

I have gone to Control Panel>Hardware and Sound>Manage Audio Devices>Recording> and set my mic to defaults. http://i.imgur.com/teHJrpa.png

I have gone to Control Panel>Hardware and Sound>Manage Audio Devices>Recording>Properties>Levels> and set it to 100, also checked to make sure it wasn't muted. http://i.imgur.com/oSe7q2u.png

I have tested another mic on my computer, and it yielded the same results.

I have tested my mic on another computer, and it sounded absolutely perfect, so the problem isn't my mic.

I tried updating drivers (they were already up to date), still isn't working properly.

I tried rolling back to a previous driver, and it still didn't work properly.

I tried using the Microphone Boost, but it just creates a bunch of static, which makes it impossible to speak to people (although it does make it pick up my voice better).

I tried using the Conference Mode feature in the RealTek HD Audio Manager, but that creates a bunch of static, as well (although it does pick up my voice better).

I tried uninstalling audio programs like Skype/Ventrilo/TeamSpeak, still no change.

I tried reformatting and rebooting windows, because I got desperate to just have it fixed...still no change.

 - So then I tried contacting ASUS (my motherboard company), and asking them what could possibly be the problem, and I told them everything I have tried, and the person I was talking to said to either try an external audio card, or RMA the motherboard because I already went through all the troubleshooting he could think of, so....

I bought a new external audio card, and it still didn't work properly, so I returned it.

(I did use the proper driver for the external audio card).

In my desperate attempt to finally just get the issue done with, I went back to MicroCenter, returned my motherboard and did a $53 upgrade to a brand new and improved Motherboard, expecting this all to finally be done and over with...nope.

I put in the motherboard, loaded windows and drivers, did all the updates, installed blah blah blah, tested my mic, and.......still the same exact results as before. Not a single thing is different.

I'm now furious and extremely desperate for a fix. I can't take this anymore. I don't know what to do, and I've spent nearly two weeks now, trying to fix this. It has put a huge dent in my work, and I have the biggest headache. I'm tired of it. I just want my mic to finally work properly.

I'm also about to just resort to taking my computer to a tech support place, and just hand it to them and tell them to fix it, knowing they probably won't be able to.
