Vista - CPU Utilization of 35% + All of the time

It looks like % Interrupt Time on core 1 is 70%. On the other core it is
less than 3%. I guess this means that there is some device(s) like a mouse,
disk drivers, NIC, etc. causing this issue. How can I find this?

The Interrupts/sec is sustained over 1000. I've compared this value to
System: Systems Calls/sec. I don't think this is a hardware issue because it
didn't exhibit this issue with WindowsXP; therefore, I think it must be a
driver issue. Any thoughts on how to track this down?

I suppose you can disable the devices from device manager and see if that
has an effect on the CPU load.

The results explain why your weren't seeing anything in task manager.

I suspect USB things?

I removed all USB devices and disabled the items that I thought were save to
disable. These include a RAID controller, network card, etc. The remaining
items would be like mouse, disk drive, keyboard, video card. If I disable
any of these, I'm not sure how to enable them.

Any other thoughts as to what I should try next?

Still not fixed?

I dunno then, I think your stuffed, if a clean install doesn't fix your
problem then I suppose you need wait for some updated drivers?

Anyone know how I can troubleshoot where the interrupts are coming from?

I solved this issue by turning off the IEEE 1394 (firewire) port in my BIOS.
The interrupts disappeared and the CPU utilization went down to almost
nothing.

I am having the same problem here.. Vista ultimate x64, AMD X2 3800+
processor. Everything is running sluggish, and when I look in task
manager, the graph for core #1 shows about 2-5% utilization, and core #2
is 95%-100%. Task manager always shows 46%-56% utilization overall,
which would correlate with the graphs. System idle process shows 95%,
and nothing else seems to ever take up more than 2-3% if I watch it for
a bit. Resource monitor shows two processes taking up user time, but
they are averaging about 3% each. Process explorer from
microsoft/sysinternals also agrees with this, nothing shows using any
cpu time at all. It even does this in safe mode.
I tried disabling firewire 1394 in bios (and I was using an external fw
drive) but that did not help. I have an ATI radeon 3850 manufactured by
Diamond, and a netgear gigabit network adapter. No other add-on cards
in this HP system.

Anyone have any further ideas? I'm feeling like a reinstall with x32
vista may be in order, but I hate doing that.

I also just started having this problem except I am at 50%. After abiut 3
minutes my PC is locked up with no responses.
