Hi:

Try to use MSconfig and disable any 3rd party services, including
Antivirus.Just MS services. Also take out your machine network cable to see
if it is a malicious software.

I hope it helps.

Just in the last 72 hours I have started to have problems with my Vista
installation. Whether I start the computer in Safe Mode or regularly, the
explorer.exe process runs up my dual-core processors to 100%, or
thereabouts.
The average usage for the process is about 60% - 80%. I downloaded
ProcessExplorer from the Microsoft website, and the culprit thread is
something titled

ntdll.dll!RtlIntegerToUnicodeString+0x67

There are now four instances of this in the Threads dialogue as I write,
but
only one was eating up my processor. Does anyone know what this is, what
it
does, or even better, how to fix it? I'm a Computer Science major and I
can't afford to have my personal computer out of commission for several
days
like this!

Any help would be greatly appreciated. I have already done every single
virus and malware/spyware scan I know of (HouseCall, McAfee, HiJackThis,
Defender, Windows Malicious Software Removal), and started up in safe mode
(the problem still occurs). On a side note, or perhaps this is related,
my
taskbar is completely frozen. I cannot access the start menu, and the
list
of open windows does not update past about 10 seconds into uptime. The
clock
doesn't update (although the sidebar one keeps going) and the Notification
area icons are inaccessible.

Windows Vista Ultimate (clean install)
Intel Core Duo @ 1.83GHz
