Windows still has all the drivers for your old motherboard installed. When changing motherboards, a clean install is recommended. A repair install may fix some of the problems or at the very least update the chipset drivers.
Easy, make sure the new drive is the only drive connected to the motherboard when you install win 7. Now, power down the computer, reconnect the other drives and change the boot device/boot order so that the win 7 drive is the 1st boot drive. The vista drive will now show as a secondary drive. If you leave the vista drive intact, you could even change the boot device back to the vista drive and boot into vista and the win 7 drive will show up as a secondary drive.
Ah thanks for asking.
1. it is slow in booting up and logging in. I have a 3.9 ghz processor and 3.1 gbs of ram (stupid 32-bit vista)
This is a completely new system that I've built, with the exception of a cd-drive and the harddrive, which i kept to refrain from redownloading everything. (if you click a simple program like minesweeper or something as soon as it shows your toolbar, it takes about 5 to 10 mins before the program even shows up.
Under heavy load, my computer appears to be extremely slow and sluggish, and loading up programs appears to be a great problem. Exiting multiple programs, even. (When it's time to shut it down, i exit out of a lot of programs, and it takes them a few seconds to realize that its been exited)
I don't video edit, so I wouldn't know.
Opening folders takes a while. I defragged my harddrive a week ago and it is still pretty slow.
2. Gaming FPS is great because of my vid card and everything.
3. I run Norton (haha) scans weekly and look for signs of anything, so I believe I do not have viruses/malware.
4. I have 4gbs of Low latency 7-7-7-20 ram installed, and it is lowered to 3.1 gbs because of 32-bit.
