Hi

I have Vista Ultimate 32 bit OEM (Self Installed) on a home built desktop.
AFAIK all drivers are up to date and PC runs very well on startup.

If left for some time (usually a couple of hours or so) it suddenly
becomes extremely slow and unresponsive. This can happen even in the
middle of working. I have a UK Network Rail Sidebar Gadget which is
constantly updating with local train times. This will always stop
respondiing and suggest that a screen saver may be running. If I go to
Contol Panel I cannot access the Performance page - if CP was closed when
this happened it only shows a subset of (usually) 12 items - even if it
had previously been open accessing any item becomes virtually impossible.
Prior to problem occurring the Performance Page states that there are no
items causing system performance issues. I have never been able to access
the Performance page once the problem has initiated!
Turning the machine off suddenly changes from very rapid to, at best, dead
slow. I have left it shutting down for over 4 hours (when I have had to
leave the PC room to do something else) and still had to finally shut down
via the front panel push buttons (physically shut off power). Using the
close all programs and shut down icon on the Start menu seems to trigger a
faster initial response, but still seems to come up against a brick wall.
Vista has never asked for a disk verification/check even though I have
forced the shut down.

Does anyone have any ideas where to start looking?

Have very simmilar problems. Started at once. The local Vista guru worked
two days on the Dell (xtp with all whistles) and said the only solution is
to
reload the Vista. Now in the process backing up all the smal programs I
have.
I will report after the reload whenever it happens.
