hi everyone
i got this big problems on my hands and i just can't make it work out. everything goes smooth till the windows starts up ... then for some reason my keyboard, mouse, wireless modem and audio doesn't work anymore

. it`s so pissing me off the fact that i rly can't fix it by myself so ... maybe you guys can help me
when i plug in an usb mouse and keyboard they work perfectly, but the computer (laptop) runs a lot slower than usual.
i tried to uninstall drivers through device manager and it always stopped responding, so i formatted my computer(only c: drive) reinstalled windows and ... again same problem
also for some reason, after i wonder around and restart my computer everything works perfectly ... for some time ...
maybe you guys can help me out with this ... thx
