What you call the "bios screen" is the system's POST (Power On Self Test). If you go into the BIOS (usually F2), you should be able to set the BIOS to report more details about the results of the POST activities. This should give you some data to post (sic) here that we can look at and give you some more rational advice.
Then, if I open the Asus EZ Flash 2 BIOS utility
It tells me I can't load the D: drive. TSSTcorp
which is a cddvdw.
Is there a way to disable the drive so I can turn the computer on,... or what. don't know ?
