I'm starting to think it may be because my power supply can't power it enough to spin the disc to a readable speed. So i am going to purchase a new power supply. I don't think that it is faulty becuase i one point it did boot from the disc.

With all due respect I doubt the PSU could be an issue.

If this drive is failing it still might work 1 in a hundred tries for example.

I have had drives act like this. Try blowing some canned air into it. Try rebooting many times etc.

On the other hand a failing PSU would tend towards more basic issues like not starting the RAM or BIOS.

You can test your PSU:

Why i say the PSU is because i have noticed that some of my case fans have stopped working even though they are plugged in. I wouldn't have thought that a brand new drive would be faulty.

Are the case fans plugged directly into the PSU or the motherboard?

I did not realize it was a brand new drive but then again some hardware is born dead.

Is the PSU new? I would test it before replacing it. Fans run so little power (>1 watt) that they are hardly indicators of a PSU.

If motherboard connections appear to be a recurrent issue I would question the motherboard.

That line of motherboards has a history of defects. An RMA might be in order.

The case fans are plugged directly into the PSU. The PSU is quite old and was carried across from an older computer to this one when i built it. The PSU is only 430 watts which i think is too low after using the eXtreme Power Supply Calculator, eXtreme Power Supply Calculator Lite v2.5, which told me that i need at least 590 watts.

OK then. Time to go shopping! Let us know how it goes.
