I will do that Raptor, thanks
If I remove SP3(and I thought about that) how hard is it to reinstall ?
I'm open to all suggestions and in the meantime, I await a snowstorm coming very shortly. Merry Xmas from Nova Scotia, Canada.
I don't think uninstalling SP 3 will help unless you uninstall SP2 as well. When you download USB drivers for a mainboard, the manufacturer often says that you should either load these drivers or update to SP2 which would lead me to believe that the support for a lot of USB controllers is in SP2 and not SP3 or SP1.
Anyhow, it wouldn't be very hard to reinstall. You can get the downloader
hereI'd keep that as a last resort and if you're in a really experimental mood. You might damage your Windows installation if something goes wrong.
Try completely uninstalling all USB related devices first.
By the way, could you try booting from a USB device to see if the ports and controller are still functioning on a hardware level? Or hooking up a USB keyboard and entering the BIOS from there. You might need to enable 'USB Legacy support' for USB hardware to work during POST.
IF you can't boot from a USB device, try going into safe mode and hook up a USB device there to see what happens.
By the way, are you absolutely 100% positive that your BIOS is properly configured when it comes to USB devices?
