I'm not sure if this is a software or hardware problem, so I will just post it here

Our power went out 2 days ago for about 45 minutes. My PC was on at the time. When the power came back on, I turned my PC back on and the normal sequence is it shows the intel splash screen, then loads windows.
But this time it stopped and froze on the intel splash screen for 15 minutes, then started further booting, to where it said "loading windows" and then the screen went black for 90 seconds, than windows desktop loaded normally.
This has happened before with power outages, but only once per outage. After the desktop loads, usually it never happens again until the next time the power goes out unexpectedly. But this time it does it every time I "restart" or when after having shut down, later turning it back on to the same thing again and again.
And I have timed it haha its 15 minutes and 90 seconds, exactly, every time for the last 2 days. Very frustrating.
Thanks for any help/suggestions. I'm running Win 7 - Pro 64-bit
