I just bought a new PC laptop (Acer 3820T-6420) which came with Windows 7 home. I have a legal copy of Windows 7 ultimate which I plan to install. I plan on formatting my HD and installing windows 7 to get rid of the bloatware.

I find the default windows install, includes most default drivers. Do I need to install the drivers from the manufacturer? I find some the drivers have these annoying popups and dont seem necessary.

Edit: I am trying to install the minimum drivers. From past experience, there are drivers I must have and there are other drivers I may want to have and and then there are other drivers that I dont need at all. For example, if I install windows and the networking works, do I bother installing the 'Lan Atheros' driver listed below? Do I need the Intel Chipset driver? Will it actually give me any benefit? I know there are some drivers I definitely need like the wireless one.

If there are some drivers I should include which ones are they? The following is the list from the Acer website for my machine:

Go to Acer's website now, before the format, and download the network and video card drivers for the laptop. To know which ones are correct, check your current Device Manager for comparative purposes.

Then do the format and reinstall, use the drivers you downloaded beforehand, and then get the rest from either Windows Update, or Acer's website.

Make sure you get the right ones: Acer has 32-bit and 64-bit drivers, depending on the version of Windows you install.

I edited my question to be clearer. (I hope) I am trying to figure out what drivers I need vs. may want vs. should not bother install – Tihom Feb 12 '11 at 18:51
Sure, but I said if you look in Device Manager, you'll be able to tell from that what you'll immediately. Most times, it's the network and video card. After Windows Updates runs a couple more times after the format, you'll see what's left and you'll then do that. It's usually things like webcam, modem and Bluetooth that doesn't always install off Windows Updates. – user3463 Feb 12 '11 at 18:56
Also try the component vendor website, sometimes it's newer than what's available from Windows update or Acer's – Martheen Cahya Paulo Feb 13 '11 at 3:59
For video cards, that's not a bad idea. – user3463 Feb 13 '11 at 5:20
