Re: all usb stopped working
4 years is the rough timeframe where the capacitors on the motherboard and particularly the power supply go bad.
Check the voltages from the power supply with this program: http://www.almico.com/speedfan.php - the figures are not always accurate when read with software, however.
Check the appearance of the capacitors all over the motherboard. The tops of them should be flat, not rounded or bulging and definitely nothing leaking. You do have to look carefully, as it can be awkward to identify slightly bulging caps sometimes.

Re: all usb stopped working
have you tried booting to safe mode and testing a usb device ?
Re: all usb stopped working
Hi guys.
thank you both for replying
1. i booted in safe mode. no change
2. i looked at the capacitors but could not see any problems.
i replaced power supply about a year ago. so i hope this is ok.(ocz gaming supply)
Your advice is greatly appreciated.
what can i try next
Re: all usb stopped working
sounds like the 5v lines blown on the USB, unless you want a new motherboard you can always buy a pci card with usb on it.
Re: all usb stopped working
thats great thanks.
if i purchased new mobo
what would be a good replacement, and is it mobo easy to change?
current mobo p5nsli
processor e6600

Re: all usb stopped working
Cheapest option is to do as above i agree....buy this....
Scan-5-Port-PCI-USB2-Card-ALi-Chipset
with change from a tenner!
Re: all usb stopped working
and very expensive delivery for a small item, shop elsewhere.
Re: all usb stopped working
boot a linux live cd like knoppix and see if usb devices work there.. it only costs a blank cd to try :)
Re: all usb stopped working
hi guys. sorry more problems.
went out and brought 5 port pci as suggested. bargain about £6
when i went to fit i found i only have 2 pci on mobo.
currently occupied by
x fi sound card and marvel yukon ehternet controller
i thought i would swap for sound card and see what happens
as soon as i plugged pen drive into usb computer switched of. i rebooted but pen drive not shown.
i took pen drive out and put printer cable in. printer works fine.

So you've gone from no USB ports working with any device to the printer working fine, but the pen drive not working? Looks like it's time to replace that pen drive if that's the case.
Re: all usb stopped working
just to keep you updated. i plugged my archos into usb. no problems.
so my issue now is
1. no sound card.
2. what would cause the pen drive to turn computer of.

I'm guessing but the pen drive may have developed an electrical short. This could have blown your computers existing USB ports. I'd throw it away if I was you - and certainly not try it in your PC again.
Regarding the sound card you could always get a USB sound card from deal extreme/led shoppe for now. Its not going to be brilliant but will allow you the time to save up to replace the motherboard etc.
Re: all usb stopped working
Another possibility is a pair of usb headphones, most bypass the soundcard, so you don't need a soundcard for them to work.
