I have a very strange issue when trying to install Vista. The install actually goes along rather quickly without errors but before I get to the logon screen, things come to a CRAWL! Both the audio and video are extremely choppy. The circular Windows Vista logo slowly fades in at about 4 frames per second and the audio is ridiculously choppy, taking 20+ seconds to get past this logo and to the logon screen. Once logged in, everything is still slow, maximizing/minimizing windows takes forever, etc. I figured this was the video drivers, so installed the latest drivers for my 8600GT, no change. Updated the sound card drivers, no change. No conflicts in device manager to point me in the right direction. I've searched the web and I can only find a similar problem stemming from VIA RAID storage drivers - I installed the latest from VIA, no change again.

Does anyone out there have any ideas? I'll be very grateful for any assistance!

Specs:
Gigabyte Nvidia 8600GT, Motherboard: MSI P4M900M2-L, Pentium 4 3.0Ghz, 2GB RAM, Vista Ultimate

Installed the latest motherboard drivers as well?

Yes, I installed all the available updates from the MSI website. I installed the latest video and sound drivers as well. Tonight I will double-check with Task Manager and see if there's any processes at 100% CPU. I thought I did this at first, but may not have. Seems like there should be something hogging all CPU cycles to make things this slow...

Was this a reformat and clean install?

I partitioned my fully working XP SP2 HD to make a partition for Vista. This way I can dual boot to a fully working XP system, while fudging around getting Vista to work...

Ok, I pulled up Task Manager and found nothing using 100% of the CPU - nothing even close. I opened the volume control, changed the volume setting so I could hear the "ding" sound, and see if Task Manager showed anything then, but as the ding was taking 10 seconds to play out, there was no abnormal processor usage showing in the Task Manager. When booting into Safe Mode, everything DOES run nice and quick. I'm not sure if Vista has the old "step by step" driver boot option, but I'll check and see if I can isolate the problem. Any ideas?

I had a sound issue like this during beta, and the next build with a new driver took care of it.
See if there is a Vista driver for your sound card from the OEM.

Were these latest drivers drivers for VISTA?

Yes, the sound drivers are the latest as listed on the MSI motherboard driver site. Version 1.72a I believe. I also tried a 1.6x and 1.5 version of the same "for Vista" drivers, to no avail. I think I got what would be considered Realtek's OEM drivers and everything gives the same results. This is very strange stuff.
