hey for the past week i hav been having a random problem on startup
my keybored and mouse dont responed it doent happen all the time i tryed swithcing round usb ports but dint seem to change and im forced to switch off my pc and start it again couple of times iv had to to this twice

You mean with the startup of your pc or startup of a certain program?

when i start up the pc

How many usb devices do you have plugged in mate?

If you have more than just the mouse and keyboard, unplug them all and just leave it with the M&K plugged in and see how you get on. Also just check you have the latest drivers for your mainboard. Might be an update with the usb and device manager might be throwing a fit.

Could also be a virus, unlikely, but possible, which interfers with the devices.

Your not using a usb hub at all?

il check the drivers all i have is keybored mouse headset and xbox contorler and speakers that hav external power suply oh wait monitor has usb conection will also scan comp to be on safe side

edit

hav updated the motherbored driver and will let u know if anymore problems
also runing anti virus scan

are the keyboard and mouse plugged independently into separate USB ports ?

If they both fail on startup (wierd) do the other USB devices still work ? (Not sure how you'd tell as you can't get past the logon screen but maybe you can).

I'm guessing that if both kb & mouse fail independently, it is actually your USB subsystem that's dying. It might be possible to plug the kb into a PS2 port if your PC has one and the little adapter to test things a bit further.

This may sound weird but we get this problem with winodows xp and intel motherboards at work. Fix, turn off PC and then switch psu off at back of PC but leave plugged in (earthed) then hit the power button on front of PC so the PSU disapates its capacitor.
Dont ask why, but it works. As I said only seems to be intel boards this weird bug.

yeah i kinda done that but without switching off psu
but sice i hav updated the drivers iv started up about 3 or four times now with no problem thanks for the advice guys

take all ya usb connections out.
start ya pc with nothing in.
when its up and running
plug them in one by one waiting for windows to install them as you go.
