Hello,
i've just changed my power supply
,a new one of 450wt for my p4 with
1gb ram and 2.99ghz processor.even
then my moterboard heats seriosly
and none of the pc games runs smothly
Please provide complete system specifications, including brand and model of your PSU and motherboard. Does your case have good airflow through it, and are any/all fans running?
