Last night I restored my machine to factory state, and I continued to have a pretty regular crash in the igfx display driver (which Windows recovers from). So today I thought it would be a terrific idea to format the disk, and start completely from scratch. I managed to format the disk, and on reboot... Nothing. Powered on (glowing) black screen. I can't get to the bios, I can't boot a bootable USB drive, I can't boot an external CD ROM (all of which previously worked). I have tried the reset button (yes, between the USB ports), and a myriad of voodoo chants. Nada. Any ideas?
