Just disconnected and cleaned (air) the motherboard and connected the PSU to the motherboard.
I got back in the bios!
Changed the bios a bit (disable sound)
And when rebooting, I get the same problem!!!
reset the bios to "default"
try using only one memory stick, try each one in various slots. run memtest86+ to find any bad sticks.
try to boot a live image *nix like ubuntu from usb/cd with the bare minimum hooked up.
however, im afraid your mobo may of been damaged by the surge.
