Hi All. The front USB ports on my pc would only work when they wanted too, i would plug my camera in and the pc would say it could not fetch pictures because of a camera error. So i would plug it into a USB port on the rear of the PC and it would do as instructed 80% of the time, when it did not work i got the same error message. Similar things would happen when i plugged my phone in. As i have had the Motherboard for over 2 years i thought it could be wearing out so i installed a new Motherboard, woops, same problems happened. After wasting the money on a new MB i was a bit annoyed. It appears to me the problem maybe be the PSU could be wearing out. I checked the memory and it is fine and the CPU is as new as. What does anyone think of this, has anyone had a similar problem. Sorry this is a bit drawn out but it kept you busy reading it did it not. Thanks people.
As this issue is only happening with the Front ports, I would doubt that the issue is caused by the PSU, which supplies voltage to both front and back ports.
It is possible that you have wear on the actual front ports.
Rear ports tend to have devices plugged in and left plugged in whereas front ports are used ad-hoc for short periods and therefore suffer a lot more wear.
As it is not likely that the front ports are easily replaceable, You may want to use a multi port extension to take the rear ports to the front of the system, which would also be considerably cheaper than replacing the PSU
Before I would consider changing the PSU I would also check the cables between the device and the ports, I've had cables fail through use on my DSLR's - luckily the ones for my devices are standard Mini and Micro USB so are easily replaceable, but I know that some devices use bespoke cables that can be expensive to replace

Since you replaced the motherboard and have tried different devices too with the same results, it could point to "power" but typically a failing "power supply" results in system shutdowns, sudden reboots, or freezing. Only USB ports intermittently not working does not suggest a "power supply" problem to me but rather something going on with your USB drivers.
It sounds like you kept the same boot drive. If so, did you install Windows fresh with the new motherboard? If you kept the same boot drive and Windows installation, you may have kept corrupt drivers too. Was it the same make and model motherboard? What PSU do you have?
If me, before buying a new PSU, I would swap in a spare (perhaps borrow one from your mate if you don't have one) and see if it does the same thing. At the very least check your voltages - what does Speccy say?
