My computer was working perfectly fine the day before. When I got off of school I immediately turned on my computer but knocked out due to my lack of sleep. The moment i woke up I saw Windows 10 installing but that wasn't the issue. As it was installing, my street had a mini blackout. When I turned my cpu on it wouldn't load and would bring me to loading operating system. I've tried entering safe mode but it doesn't seem to work. Btw my keyboard is perfectly fine I can access the boot menu and bios setup by pressing del or F 12. Please help. Thanks in advance!
