Problem with the pci.sys driver on Vista

Hi there,

Running my brand new Vista, my CPU spikes at 100%, which prevents me to do
anything. When I deactivate the pci.sys driver, the CPU comes back to a
normal activity, but my system is very unsteady.

I would like to know what is exactly this pci.sys driver. What is its goal ?
How can I find another version in the internet to try to fix my problem ?

I'd like to know HOW you deactivated it. The PCI.SYS driver is the bus
driver for the PCI bus, and without out it, you basically don't have a PCI
bus. Methinks you THINK you deactivated it, but Windows, in it's infinte
wisdom, and because PCI.SYS falls in the catagory of a protected file under
System File Protection, most likely restored any registry changes you made
and restored the proper version of the file to the drivers directory. Now
.... when it did that, it is very possible in enumerating the PCI bus again
it reordered things such that a recalcitrant child connected to the PCI bus
in a more optimum place in relation to the other PCI devices. But that
driver still has issues since now your system is reportedly unstable.

That file is updated via Windows Update when there is an update for it.

You may be right. However, suddenly my screen turned black then restarted in
low resolution. The ATI Radeon driver disappeared and was replaced with a
"vgasave" driver. Which may me think that something really happened there !

Yes certainly... That's why I need help.

I would have liked that your reply ends with something really new.

Best regards

what you get", but you're welcome all the same.

When I wrote that I would like to read something new, take into account that
it is now 2 weeks that I try to work with my computer and that I begin to
give up ! However your reply was very interesting :-) and sorry for my last
sentence.If you are right - and I think you are - it means that I can't replace the
pci driver with the PCI driver of another Vista computer, just to make a
test. Since in that case, nothing is going to work anymore... ?

By the way, do you think that flashing the BIOS could fix the problem ?

I've tried...for the worse.
I explain: I've downloaded this
http://drivers.softpedia.com/get/BIOS/Others/ECS-RX480-A-BIOS-11f.shtml for
my Elite RX480-A motherboard. Then the BIOS has been upgraded but the flash
fails because I had to set a jumper beforehand on the motherboard. I've
decided to wait, then after a while I reboot.

Now he PC is running but nothing at all appears on the screen. I'm stuck ! I
don't know what to do (I wrote from my office laptop).

What I don't understand is that I didn't flash anything...

In the process of disassembling things to place that jumper perhaps you
lossened the monitor cable or even jostled the video card. Go through and
make sure everything is seated (though you most likely have done that).
Power down and let things sit, with power cable NOT plugged into wall power
for about 20 to 30 minutes. Then plug it in and power back up. If that does
not work, find the motherboard manual and use their "When all else fails
RESET" method.

Given that the BIOS you have is the latest release, I would go ahead and
monkey with that jumper and flash it. Unless you hear something bad about
the version to which you are change, it's usually a good thing to be upto
date.
