Have you tried connecting it to your pc? If you can (i had a similar problem) access the system folder on your pc and find the file gmini400.bin and delete it. I don't know what it does but it fixed mine. (You will still have all of your files)
I'm having some trouble with my Archos Gmini 400. When i press the power on button, it should then activate the hard drive, but it doesn't. It just stays on the boot-up screen forever. What can i do?
thanks!
