Today I ordered my parts for a new build. I have an ASUS M4A88TD-V EVO motherboard, and I seemed to have been having no trouble at all apart from a dvd reader that I chose wrongly, I took out the DVD reader, and my USB ports stopped working, I saw that the mouse I had plugged in through usb flashed (the lights) everytime I inserted it into a usb port. I already have redone all my cables twice and the problem persists. I cannot do anything right now because I can't use keyboard, nor mouse. Is there a fix to this problem?
Here is a video I recorded to show you what I mean about my mouse that is connected through USB just switching on and off whilst I plug my USB cable into the computer. The light flashes on and off everytime I pull the cable in or out, when it should stay lit. Same would go for my keyboard. http://www.youtube.com/watch?v=ttKWgghusYI
Some USB Keyboards simply won't work, but I assume that they worked before -> "I took out the DVD reader, and my USB ports stopped working"
Next, my assumption is something got 'moved' i.e. MOBO. Pull the USB Headers off the MOBO, unscrew the MOBO and PCIe screws, and dangle the MOBO supported by a towel and away from anything conductive. Only use the built-in USB ports on the MOBO I/O and try again.
The only other thing you can 'try' is a full breadboard which means pulling the MOBO and using bare, I'm mean bare, minimum set-up. Another s-l-i-m possibility is a shorting CPU Fan backplate -- if there's metal to MOBO then that can cause a problem; screw | plastic washer | MOBO | plastic washer | etc... on top.
