So my thought is it's not the RAM. It took awhile for me to figure out why my fresh install of 7 was slow on my HP d4999t. Turns out I needed not only the motherboard chipset drives but the Intel Storage Manager.
Also external USB drives might be indexing which you can unplug as you sort out drivers and more.
I also install the 64 bit on 2GB RAM so I don't have to reinstall later.
PS. Yes it works fine here on 2GB RAM Windows 7 64 bit.
I recently upgraded to windows 7i ultimate (32 bit). I currently have one GB of ram and the computer is extremely slow.
I'm thinking of buying another 1 GB and putting it in. Has anyone here tried Windows 7 with 2 GB of ram? Does it work well with this amount?
