PG&E (the local electricity company) came and took out the old power meters and put in a new ones by brute force and with no advance notice in our neighborhood, so my computer went down in power.

So I went to Windows 7's drive C and schedule a Disk Cleanup (chkdsk) on the next boot up.

When it boots up, it says

A disk check has been scheduled
To skip disk checking, press any key within __ second(s).

and then after it shows

To skip disk checking, press any key within 1 second(s).

it just sits there, with no further message. the hard disc light blinks every 5 seconds. So what is to be done now? I certainly don't want to brute force power off again.
