my pc keeps shutting down and restarting giving me the option to start in
safe mode. this keeps happening ever 1 to 2 hours.

Usually Safe mode boot indicaters a driver problem. Is there a specific
function or activity you are involved at the time?

i am usually on the internet when it happens.

i am not in a specific site when it does. Sometimes it will do it as soon as
i log into vista though, but not very often.

need more info! that could be anything. are you getting a blue screen
before it shuts down? did you add anything new recently? have you gone
into safe mode and run a virus scan and before you go online try
removing some programs from your processor something in the processor
that's running could be triggering it to shut down once online.
