Hello recently I forced my PC to shut down during its bootup by holding down the power button. I know it was stupid but now when I switch it on everything seems to be so much slower. A program takes minutes to start up and even if it does, it becomes unresponsive really soon. Also I can't connect to the internet. I tried to backup up but it just doesn't do anything after I click it. Re-installing windows doesn't seem to be working either as I just get stuck at checking compatibility. What do I do!? Please help!
