You need to find the disks with the OS (10.4 or 10.5), and start from the disks.

Reinstall the software or do the hardware tests.

Info on your mac.

Your mac its pretty outdated now, maybe you want buy a new one.

What OS were you using on the mini before this problem started? If 10.7.8.9, boot to the Recovery Volume (command - R on a restart or hold down the option key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions. Then reinstall the OS.

OS X Recovery (2)

Correction - 10/7/8/9.
