Frozen again, still in the Videos area, but this time in the higher level directory of directories. First thing done today, trying to back out of the Videos section to get back to main menu.
I think I've solved this for my setup.
Over a 15 min period I had repeated freezes/lockups when I was navigating the Videos menu. I tried rebooting but it locked before the black bios screen.
After a lot of googling I removed my HD64502 gfx cardf & reenabled the onboard gfx. It booted normally & I setup the screen res, overscan & HDMI audio.
It worked perfectly for a day so I tried the HD6450 again but again it wouldn't boot.
Its been running for 9 days with the onboard gfx & hasn't locked or froze at all. So I'm guessing the HD6450 has been the cause of the freezing all along.
I've got another 6450 to try but as its working perfectly ok I think Ill leave it alone..
