secure erase frozen drive issue

I’m trying to secure erase my extreme pro 240gb through the usb bootup but when I try to clean the drive i get the message “drive is in secure frozen state” and it will suspend the system , press any button or power after 10-20 secs. to unfreeze the drive. After I select OK, my computer shuts down and I’ll wait about 15 secs. at which point I turn my PC back on, but my PC runs for about 10 secs. and then shuts off again. Is the drive clean and I don’t know it or is there an error occurring?
