The issue with the Old Custom Tower PC booting from CD seems connected to the capacitor.
I have an old custom tower PC I built a long time ago and I'm having trouble booting from any CD/DVD media. With the HDD installed, it attempts to boot from the CD first, then switches to the HDD. Without the HDD, it keeps trying the CD repeatedly until it fails and asks to try again. I've also used multiple ROM drives and a floppy drive without success. I remember the PC was shut down because of blown capacitors, could that be the reason? I understand blown capacitors can cause boot issues, but they might also prevent booting from CD.
Based on age, it could struggle to boot from CD without a boot floppy and many older media didn't work without one either. Floppies tend to be quite inconsistent, so unless you recently made a new one, I'd recommend creating a fresh one. If the cable orientation is incorrect, it might appear functional but won't actually start. What exactly are you referring to with the ROM drive?
