Are you sure your RTC (real-time clock) battery is not discharged ? Maybe try
replacing the battery.

I used to experience these issues (has nothing to do with RTC) some years ago,
mostly due to crappy SMPS, bad power/data cable which got fixed after I
replaced its SMPS.

And what's that error message you get from BIOS ?

So are there total of 3 drives (including the DVD writer) connected in your
box ?

Probably.

Very less likely.

For extended troubleshooting, you can get a POST card[1] (or Debug card), a
PCI card which displays progress made by BIOS by emitting various codes as it
progresses to the I/O port which POST cards hooks itself to, and used to sell
for INR 100-150 few years ago. You'll need your motherboard manual (or a copy
of Upgrading and Repairing PCs[2]), which contains a table to interpret the
codes.

Maybe start with replacing RTC battery, if you've not already done that.
