Dell Inspiron All in One runs slowly after power outage
Hello!
After an accidental power outage, my Dell Inspiron All in One started loading Windows very slowly. When I turn on the computer, a window initially appears stating that the voltage is not suitable or something similar, but the system will correct it. Yes, but when I click Continue, the computer loads slowly again. Applications also load slower than before the power outage. What is the reason for this and how can I fix the problem?

Power outages and surges can sometimes damage hardware components or affect the power supply unit (PSU), leading to voltage warnings and system instability.

The AIO Dell ac adapter or DC jack in AIO is possibly defective “zapped” by transient power outage voltage spike. Therefore you get error of wrong wattage adapter detected. Enter bios to check >AC adapter tab to verify. In that scenario bios automatically down blocks cpu to crawling slow frequencies
