i was using a intel p4 PC, several days back it started to shutdown due to processor over heating. I removed my PC and cleaned the heat sink and fan. and the then my pc worked fine. two days back my pc didn't detect my hard drive. i had a 160 gb sata disk. i noticed that the disk is not spinning. so i removed another disk from my other PC which was working fine and fixed it to it. i also stopped working.. i tried my dvd rom and it works fine. when i fixed the same cables with my dvd rom it works fine and detects by the bios. but when i use a hd it becomes unusable. today i bought s 320gb brand new toshiba hd, i tested it and it worked fine at the computer store.bt when i use it my pc, it does not detect from the bios and when i try to use it in anther pc its not detecting too why is that, i just cant figure it out... if there is a fault in the board or cables hw com my dvd rom work without any problems with the same cables and ports?? can some one please help me... all i need to do is install windows. bt the hd doesn't detect at all
