You could try the old pull the AC plug, wait and then plug it back in and try again advice.
After that you go to google.com and type "THE DEAD PC" to learn about PC REPAIR.
Hi I recently installed micron usb recovery software and jus after it finished, I clicked "finish" then my sceen just went blank. I tried to restart it but there was no boot sequence but the power and hard disk led are on. The hard disk led jus freezes,no blinking to show activity. My pc is a generic on with an intel celeron 1.7GHz processor. What should I do to get it up and running?
