PC SHUTTING DOWN
need some help i have a hp here are my specs
amd athlon 4800 64 x2 dual core
heres my problem
when i try to burn a dvd using convertx to dvd my pc will shut itself down.
it happens during the convert process not the burning process. this is really frustrating because i have replaced the original burner because it would write fail during the burning process and waste countless discs. i had replaced it with a LG burner thats when it started shutting the pc down. also at the same time i installed a razer death adder mouse. so i took the LG burner back and exchanged it for the HP branded burner. i thought i had solved the problem until today when i was trying to burn a movie, download a movie and play COD4 at the same time. it shut the pc down again. so i rebooted and tried to burn the movie without doing anything else. it shut off again. What am i doing wrong??
oh 2 months ago i upgraded my power supply.doubled the power that the factory one had.
