Vista Install Window(eVGA 780i/8800GT)-Problem

Hi Guys,
I have used Vista 32 bit on my laptop for a while. So, I decided to use it on my new system that I built with following specs:
Intel Q9450
eVGA 780i
eVGA 8800GT
500 SATA HD(Green Power)
Sony IDA DVD burner

When I boot from CD of Vista, it loads the system files and all just fine. But, after it's on log on screen, it should show the option where we select language and all that right? It does show up, but after 2 mins. So, for 2 mins I only see the wallpaper and after 2mins that language selection option shows up. Same problem afterwards for other windows. Every time I hit next, the next screen shows up after 45secs. Whereas, when I install it on my laptop, it's fast. Gap is about 2-3secs.

What's wrong?

Also, Every time I boot up, I have to hit F1 to continue; Is there a way to bypass that?

 

Beta 2 used to take 20 minutes before showing up on my old desktop >_>. I guess it's because it's loading the drivers or something.

 

I've no problem waiting but what amuses me is that It loads alright on my laptop which is Core 2 Duo, 1GB but loads after a while on a new rig.
