System randomly reboots

[oldman]

Recently I installed SP1 for Vista Business. The SP1 update was the
last thing added to the system. Since then the number of crashes and
random reboots has increased dramatically. So far today the system
has rebooted three times.

Is anyone else experiencing this problem? if so have you found a
solution.

Thanks.

The first thing I would do is to try and check the CPU temperature
and/or try to add some cooling for your computer.

I say that knowing it may well be a software issue, but it is always a
good idea to eliminate hardware stuff as well and I don't know of any
software issues that might cause it, but then I certainly don't know Vista
all that well.
