Dell Optiplex gX520 will not boot beyond the splash screen.
Unable to go into the BIOS; computer does not acknowledge keystrokes on the keyboard so pressing the F2 does not work.
There are not post code beeps.
The lights on the front panel are 1 and 4. Both are green. Dell's online diagnostic for lights does not include a description or explanation for this pattern.
Also, the floppy drive light is lit up green, and running, though there is nothing in the floppy drive.
