That would certainly be a downgrade!

What do you mean by "the Cd's For Vista"? You would need a Vista retail (not OEM) installation DVD.

You'd also need the Vista drivers (chipset, networking, graphics, etc., etc.) so make sure HP makes them all available.

I would be very surprised if HP still has available drivers for Vista. It was garbage when new, and not very popular or long-lived. The only thing worse was Windows Moron Edition (ME).

HP Pavilion Slimline 400-314 Desktop PC (G4A91AA)

Its support site has device drivers only for Windows 8.1 64-bit and Windows 7 64-bit.

Its product specifications section lists these primary devices:

AMD Radeon HD 8240 integrated graphics (combined with the processor)

Realtek ALC662 high definition audio

Realtek RTL8106E-CG 10/100 Mbps ethernet

Atheros AR5B125 802.11b/g/n wireless half mini-card

-------------------------------------------------------------

I remember reading something awhile back about HP making it difficult to downgrade a new computer with Windows 8.1 to an older operating system.

Even if you're able to do it, I would switch to Windows 7 64-bit and not to Windows Vista 64-bit.
