Desktop still on when not plugged in to power supply?

Just like the title says, I unplugged my desktop and it was still running. It ran for about 1 minute. I've never seen this happen before, and I don't even think it's possible. Maybe there was still enough energy to keep it running for a while. What do u think happened? (I'm afraid to turn it on cuz i dunno if its gunna blow up!!) O and this is an Emachines pc, and it's not very powerful.

My rabbit went behind my table and she has a habbit of trying to bite through my wires. She broke 3 Xbox controllers and tried to bite off my dog's tail. If she tried to chew through my pc wires, she could have gotten shocked to death.

Edit: O yea I have a rabbit

Anyone want to buy a computer that is possessed by the devil? But could a possessed computer have any link to why a lot of family members have died lately?

( The story about my dog and my rabbit would have been longer, but I didn't feel like talking about my dog. He had to be put down in December, about 2 weeks before Christmas. His name was Lance. He was a Golden Retriever, 11 years old, and lost a back leg in June do to cancer. What me and my family didn't know is that he had a brain tumor which very slowly started to make him go crazy. He looked and coughed like he thought there was something stuck in his throat, but there was nothing wrong with is lungs or throat. A day before we put him down, he had a very bad seizure that damaged his brain and made him forget how to walk or even use his legs. A vet told us that it could be a once in a liftime thing and that it is possible he won't have another seizure for the rest of his life. They were wrong. The day after his seizure he tried to get up and it triggered another seizure. An hour later, we carried him to the vet and he was put down. The vet told us in June that if he didn't have his leg cut off, it would be a matter of days until he died. I am glad that I had him for those 5 extra months. He was a dog who tried to play with cats, and deer, and sometimes birds. He got along with everyone except for people he felt are very dangerous. I don't know why I stopped to type all this out, but I'm glad I did.)

I unplugged my power cable from my surge protector

I'm gunna try to turn the pc back on and see wat happens

Well I turned it back on and guess what I broke: Sound card fried and hard drive failed. I'm gunna see what other things I broke.
