I have just installed a dvd writer and 2nd hard drive into my pc but on switch on it just goes to the page from which you can setup Bios but does not go any further, i.e windows does not start up. I unplugged the power connector to the second h/drive(slave, which is brand new completely empty) and the PC starts up ok. I am running windows XP and have two dvd drives on one ide connecter and the two h/drives on the other ide connector.

Any ideas what it could be?

Also I did try just adding the second h/drive before adding the second dvd drive and the PC fired up ok but when I looked on My Computer I could only see one h/drive(c drive)but in the bios there were two and in system manager also two h/drives could be seen.

Could it be that I need to install the SP1 pack for XP?
