Cogumas

I'm having the same problem. Works fine, but after few hours or days when it stays off, the bios breaks and only appears as blackscreen. For my luck, i'm using a PC, i took the battery to restart de BIOS and it booted normally. But i'm still about to discover whats breaking my BIOS. I couldn't run the "run me" app. But i'm not sure if that's waht is causing trouble.
