Had this computer since like 2007, hp pavilion slimline s3600z

Never had an issue with it, turned it off last night to go to bed, shut down normally, came home from work and tried to turn it on and it won't turn on. After 20 minutes on the phone with hp, the Indian I could barely understand told me she couldn't start to help me until I payed 25 dollars for a help session... So I said no thanks bye!

Power led on the back of the case turns on solid when I plug it in, no sort of response at all when the power button is pressed. No storms today, all other stuff in the house works fine. Tried a different outlet, tried a different cord and checked all the circuit breakers, no change.

Halp I need my computer
