keyboard backlight "works" but does NOT get bright enough can only slightly see the LEDS while looking at the keyboard from an angle.
only the USB asus charger+ port works for anything the other 3 normal usb 3.0 ports do not detect or charge anything,
any help or suggestions would be appreciated

Well in part that's good to hear, problem is smaller now. Have you any friend that has a multimeter to check the pins on the usb ports and see if their any current flowing (only if you know what you are doing, we don't want to cause any short circuit)? Are the other usb ports listed in the device manager?

my multimeter crapped itself ages ago.. but i know nothings flowing through it as i plug in a battery charger and nothing is coming out of it, im pretty sure even if it was a driver issue it should still be able to output 5v. ill take a screen shot right now

I recently purchased an Asus G750JX off eBay for a good price, it was second hand and when I got it everything works fine except for the USB ports, Webcam and the Backlight. I formatted the hard drive to Windows 8.1 straight when i got the laptop. I noticed there was some green dried stuff or corrosion in the usb ports so i thought it was that so i cleaned them out with a q tip and isopropyl but it still didnt work. I tried opening the laptop up and saw that none of the solder connections were broken on the usb ports. Only 1 out of 4 USB ports work the one working is the one on the bottom right. Does anyone know is this is hardware or software problem. Ive also tried installing the ATK package but back light doesnt work and the webcam does not also work could anyone help me out with what i should do?

Hi hyzing, and welcome to the Asus ROG Forum.

1. Open Device Manager.
2. Scroll down to bottom
3. Expand Universal Serial Bus controllers
4. If any of your USB devices has a yellow icon next to it http://res2.windows.microsoft.com/resbox/en/6.3/main/e169d2bc-146a-42ca-8b23-6e1831225a6b_13.jpg, Windows identified a problem with it.
5. Open properties for the device with the http://res2.windows.microsoft.com/resbox/en/6.3/main/e169d2bc-146a-42ca-8b23-6e1831225a6b_13.jpg on it.
6. Check the error code for that device.

Most common error codes are Code 43, that's hardware related with your USB device, ( faulty connectors and cables) that's most likely not your issue.
The other common error code is error Code 28, (There could be a problem with the device driver or your USB hub) that's most likely your issue.

You can try updating the driver in the driver tab, just click on "Update driver"
Now if that's doesn't work you can uninstall the driver with the issue, then restart Windows and see if Windows can fine the right driver.

Hope this helps my friend?
Good luck, and come back and let us know how it goes.

Check out the thread I just found>>>>G750J USB ports stopped working (http://rog.asus.com/forum/showthread.php?52945-G750J-USB-ports-stopped-working)
Seems that a Windows update is the problem!

im currently updating windows 8.1 and seeing if that fixes the problem but it probably wouldnt as 1 usb port already works

i also have windows 8.1 and it seems we have the same usb controller (mine is g750jz), i am not sure but it seems that you are missing a couple devices compared to mine.

UPDATE, tried plugging in a batttery charger for 5v WHILE in BIOS and the light came on but it was very dim compared to the asus charger plus port, seems the usb ports are fine except there is something peripherals from being detected while in windows.
