Salam to all members,
My PC specs are:
Processor - C2D 2.0Ghz
RAM - 1GB DDR2
Graphic Card - ATI Radeon HD 4650 1GB DDR2
HDD - Segate 500GB
HDD - Western Digital 80GB
DVD ROM - HP
Current power supply is A-open's which delivers 300Watts. The problem I'm facing is that after running smoothly for around 2 months, my 500GB HDD started shutting down while computer was running. I has happened 3 times so far in last two weeks. I got this one in replacement of another 500GB HDD which faced same problem and after a few times it never worked again. Now the new one is behaving in the same manner. I've disconnected my graphic card and DVD Rom and the result is that hard disk is running fine again and no shut downs.
My questions is that is there any problem with HDD? If not and the current power supply is insufficient then what should be suitable power supply keeping in mind my PC specs and that I play games and watch HD movies very often?
P.S. Someone is selling me Dell's original 400 watts power supply (used). Would that be good if Power supply is culprit?
