Problem with 512MB Pi

[pocster]

Thanks for the quick info.
Just flashed with original .img and it's up fine i.e. I have done nothing.
Just rebooted 3 times from the menu so good i.e. not a memory card issue I can assume.

Shall I continue to 'add' things until the black screen and then supply a log or just skip straight to your suggestion???

thanks

p.s. appreciate the quick replies. Assuming I get this working and rebooting reliably do you have a donate button??
