Slooooooow Vista

[Trackbikes]

I´ve just built a new PC 4gb ram, intel quad 6600 Asus mobo.

I installed Vista ultimate on it and it´s taking 5 minutes to start up and it took 5 hours to install COD4!!! everything is very slow

I installed XP Pro 32 Bit on it.. and it performs as fast as i expected

I installed Vista Home Premium from an Acer recover disk i had laying around 32 bit again and once again it´s quick

Does anyone have any idea why Vista ultimate would be so slow

I've found since moving to Vista about a week ago that it's been quite disk intensive. So I downloaded a nice free defrag software from the makers of CCleaner, it's called Defraggler.

So far it's taken nearly 8 hours on and off and it's still defragging my main drive. It's found 9Gb of Fragmented files!

It's about halfway through now and already the PC is x10 more responsive.

Perhaps try a defrag mate, and like people have told me, disable the automated Windows Defender scans and turn off the power features (or at least set it to Performance). Try and disable any unnecesary services as well.

That won´t account for the fact that the install was on a new disk and that 32 bit Vista works fine.
