Sony Vaio PC sad issues

This Sony Vaio desktop, M\No PCV RS 420,
is a Intel based PC it has a DVD R-RW drive a 512 mb of ddr 3200 ram, and run on a 2800 ghz CPU, I bought this PC in "as is" condition with no Hdd,
I was told that the Hdd was taken out cause of data in it, no further explanation was given,
I said to myself this is a piece of cake to fix. Well not so fast buddy...
I started by installing a brand new Hdd, set it to master (formated it on my spare test Rig) checked all the cables for a positive fix,
also I double checked that the optical drives where pinned correctly,
Then carefully vacuum the scum dust out of it.
When everything was set just right, I proceeded to boot it and check the BIOS setting (F2 key) to make sure it boot to CD.
Here is when the troubles started, the computer boots fine, the video card has no issue, there is just one normal short beep upon booting, sony logo and jingle is there, the BIOS is accessible easily,
but it doesn't recognize the Hdd, CD or floppy drive, nothing is there, the Bios is easily navigable and all the switches works.
I setted the Bios to defaults but still no luck,:eek: :mad: :D
I'm beginning to suspect that the Mobo is gone south it seems to have a IDE issue.
Thx a billion

Then carefully vacuum the scum dust out of it.

Vacuum cleaner generate a lot of static electricity.
Static electicity like that has been know to kill a computer.


Have you checked in BIOS [setup ] to see if the ide stuff is enabled?
