Check all connections and try again. Use a Volt Meter on the PSU to see if it's up.
6 GB Ram
1.5 TB HD
Installed 2nd 1 TB HD and computer wouldn't boot.
Removed the second drive and still will not boot also keyboard and mouse, both USB, have no power.
All the fans spin up. So not a total loss of power.
Disconnected all external devices and still nothing.
Yes ,I have 300 Watt PSU
checked the HD voltages at a spare in-line MOLEX connection
With the HD in place and connected as well as DVD Drive Connected.
Red - 5.05v / Yellow -12.04v / and Orange wire at the MOBO connector. 3.4v
Also unpluged the power to the DVD drive to see if that made a difference by reducing load. Still Didn't boot
Checked all connections, data and power , all seemed ok .
Any chance with the voltages looking ok it still is PSU? Can get a 450Watt PSU for $50. which I probably will anyway.
