poor performance xp to win7-64 upgrade

Have you updated your BIOS? I saw an a BIOS download while cruising the HP support site for your motherboard.

Have you also tried Windows Update, you may be able to find the ACPI drivers on there if Microsoft supports your chipset.

My current motherboard is a ATI 690G chipset with X1250 onboard video. There's no chipset drivers for my motherboard but it all detects on first install with default drivers. For my videocard I have to use Vista drivers but all works well, ATI support says the drivers are compatible with Windows 7.

If you had came here earlier then you wouldn't have to upgrade you videocard, the ATI drivers I'm using also supports your onboard videocard.

Okay made some headway, but I fix one problem and another crops up.

Went through HP ran the USB device update at http://support.microsoft.com/kb/976972. Fixed the missing driver on the 1394 OHCI. The ACPI driver was for the AMD Away Mode, fixed that as well. The Lacie Big Disk Quadra is still funky- and can't find the driver for it.

As for the BIOS, I can't seem to find anything on it. Looking up the support from HP on my machine the only update that is shown is for the Lightscribe, which i have never used. The current firmware on my machine listed in the BIOS is - Core 6.0 / BIOS 3.47 03/03/2006. Is that the current and if not where in the world do I find the updated one?!?

New issue is with ATI I/O Communications Processor USB 1.1 OHCI controller and ATI I/O Communications Processor USB 2.0 EHCI controller. The error message in Device Manager says that "the device cannot start (Code 10)". I am able to disable both, then enable and the work fine, but on restart they go right back to the non-starting error. Ideas?

And thank you all so far with your help! I am seeing some better performance with with these little fixes.

You really should reformat your HD and then install Win 7. The Windows 7 disk DOES have the drivers you need for your 4350 card. I know because I have the same card and the install found it, and installed the drivers.

You should probably also do a defrag and run chkdsk /r on your boot partition. If all that doesn't help, rebuild with a reformatted HD.

Good to hear it's getting better.

On my system all three ATI I/O Communication Processor drivers in the device manager are under System Devices, sounds chipset related to me and should have been recognized and installed with Windows7 default driver upon installation.

Could also be a BIOS related Power Management option in the BIOS. Something to do with ACPI enabled/disabled in the BIOS...?
