I was wondering because if I try to startup my notebook with a usb external HDD on,it freezes while the 7 logo tries to load.I searched around & many have this problem.Seen same question over & over with no clear answer.Basically it boiled down to windows 7 &/or usb software being the cause.So the chipset came to me.I never downloaded a chipset driver on this laptop.
Honestly acer sucks with needed drivers for older models.Look at what drivers it shows.

Almost all need updated & they don't even show a gpu & hdmi driver for my notebook.Yes its the same model I have.
I went ahead & downloaded the chipset driver.Seems like the usbs load much faster now & the irritating auto play popup quit showing up!
Haven't tried to startup with external HDD on yet though,hope it fixed that.
Thanks for the reply though.Much appreciated :)
