The other day my computer would not boot. I went into the BIOS and there was no hard drive detected.

I opened the case and checked to see if the cables were tight. Everything seem OK. I also removed the power connector from the drive and replaced it with a different one.

The system booted fine and it seem to be running OK again.

My questions are, If the power supply connector was bad, would the BIOS still detect a drive present? Not to say it would function, but, would the BIOS detect it?

This is a month old power supply from newegg. If one connector went bad should I replace the whole power supply asap?

Finally, I am using round cables that were supplied with my board (3 weeks ago). Are ribbons better and should I replace the cables with new ribbons?

I would suspect a defective Power Supply. But what are your specs. OS, Board,etc..

You didn't say whether the power connector is the old 4-pin type for IDE/ATA drives or the newer S-ATA type. The 4-pin types are very simple and you will probably be able to see any manufacturing defects. With the supposedly bad connector try pulling firmly on each of the 4 wires in turn. If any pull out then the cable is defective.

If the connector is the S-ATA type it will have 8 wires. Pull each one of them firmly to see if any pull out.

If no wires were pulled out by you tugging on them try using the original bad connector again just to see if it happens to work. If not, either plan never to use that connector or return the power supply for a replacement.

Try replacing the BIOS (motherboard) battery. If it is bad when the power is off the BIOS will reset to default and clear all enters. This includes HD, CD/DVD, and add-ons, like video. This could result in hardware conflicts.

The four-pin Molex connector could have been fine, but the rail on the power supply could have been bonkers. This is a good time to have a power supply tester or at least a multimeter. They aren't expensive, but they will show if there is no power at a plug. There are connectors for the main power plug, the four-pin, the regular Molex and separate LED's to show that everything's OK. They have their limitations, but can show that the lights are on, even if nobody's home.
