Vista will not boot cnsistently

[Guest]

Situation: New Vista-ready laptop; Laptop running great for two months;
increased memory to 4GB; Using BCDEdit added IncreaseUserVa 3072 item to the
boot configuration store.

Laptop now failes to do anything at power on 50% of the time. Always
eventually boots after a couple of power resets.

Help appreciated.

Apparently you have a misconception of exactly what the "increaseuserva"
command actually does.

increaseuserva is unaware of how much RAM is installed on the system. The
only thing it does is set the amount of address space that is available to
the system. What you have done is to restrict that address space to 1GB.

You need to set it back to the default of 2048.
