slight Driver Issue... Options

[jutzy]

Windows 7 has started to play up, whenever i restart my computer i cannot use my USB keyboard and mouse and my network cards dont work


i have had to use a ps/2 keyboard and mouse..

i went into device manager and i saw that all my usb ports failed to start and that my network cards also failed to start... to fix this i had to click uninstall and then rescan for hardware changes... after that it worked almost instantly.

I want to know why it is doing this and how i can fix it...

I dont want to have to take two keyboards and two mice to respawn so any help is aprriciated:

P.S I dont realy want to reinstall os but if i have to i will - Last LAST FINAL Resort
