Hell yeah! After almost two days of troubleshooting of my computer it came back to life. It had damaged files in boot sector, damaged drivers, hard drive raid 0 connection settings was changed in bios (by itself?!) and many more. I don't get why it happened. Virus? Just because it's windows? I'm trying to care about my computer but you do not know the day or the hour when something can screw up.
By the way. I really want to move on apple device. Anyone could donate me, please :) ? I can offer you a really fine logo or other design.
