Try slaving your HD first to another computer. If its still readable or accessible. Assuming you had made the correct assembly,installation of OS and drivers. Better yet reformat(HD) it from another computer and use it to point to another hardware problem on the unbootable CPU.thanks but i dont believe it can be that ... it wont even boot up to bios.... nd i have tried unplugging both H/D and put in my windows boot disc and ... nothing...
ALSO there is no beeps:(
Although i am not a Techguy but i just want to give my take on this problem, PC not making a beep sound and the BIOS not loading clearly show hardware incompatibility and nothing else.  Check to make sure the "all the IDE'S" are snug in its socket: also the jumper of the HD is Primary master.

If these wont help better take your PC to a Tech personnel..... Quote
