I received a new 8600 GT from BFG and had the same problem with OS lockups
on both XP and Vista, both 32 bit.
I checked everthing, BIOS settings, SLI card between PCIe slots, latest
NVidia drivers, ran CCleaner to get rid of the
previous ATI drivers and all to no avail. After some more research I
believe I found the problem, although the solution
is a new MB.

Apparently, some PCIe 2.0 vids do not work well with some PCIe 1.0 slots.
It's an interface problem. My rig is over 3
years old and I've been wanting to upgrade anyway and this problem tells
me
it's time to upgrade.

Thanks for your all your help.

your problem may be much simpler. Please specify all of the hardware
in your system, including CPU. If your rig is > 3 years old, I suspect
that the +12V supply may not be able to handle the load. The +12V is
the principal supply that powers the CPU, any modern video card, your
hard-disk(s), DVD/CD rom-drives.Typical symptom of insufficient +12V
current is the general flakiness that you describe. Highly unlikely
that the PCIe2.0 spec on the 8600 has anything to do with the problem.
I keep close track of reports of any such interface problems and yours
is the first speculation of that, especially with the A8N-SLI. I have
a A8N32-SLI and it runs flawlessly with a 8800GT (PCIe 2.0)....

My rig has the following:

Antec 430W with a 24 pin power connector and a 4 pin CPU connector,
A8N-SLI Proactive Series,
AMD 4200 CPU,
2x1GB medium performance PC3200 OCZ RAM,
ATI Radeon X300 Video Card,
1 Memorex DVD on PATA,
2-36GB WD Raptors on SATA,
1 Floppy,
1 WinTV USB2 card,
1 Samsumg 226BW and 1 Samsung 932B on the X300.

Bios is at default settings (no OC'ing) and in BIOS and Asus Probe all temps
are fine.
Except for the MB which is 2 1/2 yrs old and the CPU which 3 yrs old,
everything else is 3 1/2 yrs old.

Do you think a new 550 or 650 power supply could solve this?

TIA,
john
