|What "USB Object(s)" are you plugging in ?|
Do all of them not work, or only some of them?
If some of them work, e.g a USB mouse or keyboard works, but not a printer, you probably have an IRQ sharing problem.
Did you read and understand the info at the link in Response 2 ??
Did you look in System Information to see if you have an IRQ sharing problem ???
Did you check your bios settings to make sure the current reading of +5v, +3.3v, and +12v is within 10% of their nominal values?
You could try re-loading the USB stack as I described at the end of that info, but it may not help if you DO have an IRQ sharing problem.
The USB controller(s) is(are) enabled in the bios Setup by default.
"It says in device manager the USB Ports are working properly..."
probably indicates it is / they are enabled.
If you're not sure, load bios defaults in Setup, save setiings
Look in the mboard manual and make sure the wiring to the front USB ports are correctly hooked up on the USB headers(s) on the mboard.
If you don't have the manual, download it from here:
If none of the above helps....
If you're sure you don't have any visible evidence of failing capacitors or other mboard damage.......
We've heard of a few cases in Topics here where the built in USB controllers have been damaged, but it seems that's quite rare.
It's usually caused by a power surge or spike, or a power failure event, or a lightning strike on the power grid somewhere near where the computer is, or could be caused by something on the mboard being shorted by something the user did.
In that case, you could try buying and installing a PCI USB 2.0 controller card (or two) in a PCI slot(s) - they're relatively cheap - they can have from 2 to 6 USB ports, up to 4 externally, up to 2 internally.
However, don't install it in the last PCI slot closest to the center of the mboard - that slot is forced to share it's IRQ with the video, and only PCI video cards are likely to not have problems when installed in that slot.
However, I don't know whether the ACPI features of the bios will work when you plug in USB devices into only the card - e.g. moving a mouse may not "wake up" the computer.
