Nvidia vs. ACPI Power Management
Hi all,
We're working on a very hot, new machine (Pentium 4 2.2GHz, Abit TH7ii RAID motherboard, 4 x 256M RAMBUS (Samsung and Corsair), Nvidia GeForce4 Ti4600 AGP 4X video, Creative Live 256 PCI sound, Plextor 40x12x40 CD-RW, 16x48 DVD-ROM, 120G WD U100 hard disk, WinMe). It's a "wow" machine, but . . . have we got problems!
WinMe load ran without a hitch, hit the desktop and looked fine. (Our hard disk is partitioned as one big FAT32 partition). The only strange thing to this point was that we set the RAMBus to 300MHz (known bug in this motherboard). Intel Chipset Drivers loaded fine; Intel Applicaton Accelerator loaded fine; DirectX 8.0 loaded fine; RAID drivers loaded fine.
This is when the trouble started. We loaded video drivers (Nvidia Detonator v28.32 for Win9x); upon reboot we got a Blue Screen:mad: 0D : 014F : 00004EB7 . I've noted this address because it's very characteristic of the problem. Reboots show a lot of strange behavior, such as hang on a black screen, black sreen with flashing cursor, white screen, white screen with WinMe cursor. Msgsrv32(Not Responding) errors are common.
Here are the strange observations. If you right click the desktop, the New option is on the bottom, below Properties. If you go to Display Settings | Screen Saver | Power Saving, the Hibernate function is missing. Systray is absent from the System Tray.
We tried the following (unsuccessfully) to get the video to work. Disable Power Saving options, set VGA mode (640x480 16-color); clean Registry; Scandisk; set Video BIOS not cacheable in BIOS; disable every possible option in BIOS power management; disable RAID controller in BIOS; update the video drivers to the very most recent v 29.42; uninstall the Intel Application Accelerator; new motherboard; new power supply; new memory.
It appears to be some deep conflict between ACPI power management and the Nvidia video drivers. The only "positive" thing we've been able to do is to enter the Safe Mode and change the GeForce 4 display driver to a dumb VGA driver. The system then boots and shuts down faithfully with no errors. Of course, it looks terrible. We loaded the Creative sound drivers and the sound works fine. We also loaded Roxio CD Creator, and it works fine. But, if we revert the display driver back to the GeForce 4 Ti 4600, the system Blue Screens, hangs, gives lots of strange errors, etc.
Any ideas? We're out of 'em! :confused: Thanks, in advance, for your help!
Best Regards,
Shaun
