Hello, Im very sorry I couldnt be as descriptive as possible in my tittle description, I will do so in full now. Last night a storm caused the power to flicker and then go completely off and on for a few minutes. Now during the boot up process on my fathers computer, I get a prompt screen from windows telling that due to a incorrect shut down I should choose a method of booting; safe mode, safe mode with networking, start windows normally.. (you know the rest of the gib) If I tell windows to start normally, it gets to the final booting phase showing the small blue progress bar, but the computer resets itself. It also will not go into safe mode, nor safe mode with command prompt, no kind of safe mode what so ever. Essentially, the computer gets right up the point of finally kicking 100% and then a reset which brings me back through the normal booting process and to the choose a method of boot screen.
