Flashing Screen after Windows load screen

I don't know too much about computers and I just got a hand-me-down Dell Precision 320 PC from my dad just last weekend and it just crashed. I got a message saying something crashed and if this was the first time I saw it I just needed to reboot my computer. I proceeded to do so and then I got the mysterious black screen with movable cursor hanging scenario. I booted up the advanced boot menu and went to repair computer to "Last Known Good Configuration" and since then it boots up to passed the windows loading screen to a stock windows 7 screen and it flashes about every seven seconds with the cursor blinking to loading something back to idle. It hangs here until I turn it off. I am not sure if this has anything to do with the situation but there have been a couple of blackouts in my house due to heat that caused my computer to shut off a couple times.

Safe mode gets the same results
SFC found no errors

System:
Windows 7 Ultimate 32bit
Intel Core2 x6800 @ 2.93ghz
8GB Ram

If there's any other info I can provide without being able to boot my PC, I'd be happy to comply.

Can you boot in to safe mode? Turn on the PC, and continually press F8, then select Safe Mode.

When I try to boot up in safe mode I get to the same flashing screen but in a different resolution

Have you tried any startup repair options?

I tried autofix and it said nothing was wrong. I tried running SFC in command prompt and going back to "Last Known Good Config" all to no avail.

Did you run SFC 3 separate times?

How do I do that?

Run the sfc /scannow in command prompt in the startup repair. Then reboot, and do it again, then do it once again.

I tried that and nothing happened. I did some fiddling around and got this message "\Windoes\system32\drivers\ksecpkg.sys is either missing or corrupt. " So there's the problem and now I just need to find a way to fix it.

ksecpkg.sys is Kernel Security Support Provider Interface Packages, so that's what is missing. Do you have any restore points?
