I am using an HP Pavilion 734N and I installed a sony dru-734n dvd+/- r drive in my computer about a month ago. i installed it as the slave drive to my lg gsa-h42l dvd +/- r drive. It worked fine when i first installed it, but now for some reason the fan to my power supply is running extremely fast. i removed the sony drive and the fan stops running fast. is there any suggestions as to what may be causing this to happen and to fix it or should i just not us the sony drive?
