Vista - 100% CPU usage

05-29-2008

Take a look at the sysinternals process explorer tool. That allows you to
see what the threads inside the offending process are working on. Then you
might be able to see what system component is using all the CPU by looking
at the stack of the thread with the high CPU utilization.

My guess is that it could be some virus scanner (or similar) that is linked
in dynamically into each program. Uninstall everything that is not necessary
and update the rest to the latest version (including applications, device
drivers).

Ok, as mentioned prior, I tried the clean-boot and tried to discern any
specific process causing my CPU issues. However, this came to no
avail.

Current update on the situation:
It appears whatever my active program running is, that which would
normally consume the most CPU use, is consuming the majority of the
CPU, up to 70% of it. Whether this program be MSN, skype, task
manager, IE, and so on. And some other random running process appears
to consume the rest. I'm uncertain why there is a lack of any
particular type of program causing this. Using process manager I
couldn't find anything linking any of these programs.

Any further ideas would be appreciated. At this point I fear I may
have to do a clean reinstallation. I rather not do this due to time
restraints, but if it's all that is left, I'll make do.

This is totally off the wall, but could your power management be
underclocking the CPU when the system load is low? In theory, dynamically
underclocking the CPU until the current load just fully utilises it saves
the most power, compared with running the CPU at maximum speed all the time
and having it only partially utilised.

I'm sure this is available in various CPUs available from both Intel and
AMD.

Sorry I can't help more.

It is also possible that the CPU is being slowed down due to overheating if
the laptop fans are partially clogged or the laptop is not setting on a hard
surface where the fans can their air from.

I'd like to say thanks for the referral to Process Explorer!
