A few months ago my pc was conducting a windows registry update in which it failed to complete as it closed itself down in mid process and then would not fire up again. The fans spin for half a second and then that is it.
I purchased a new power supply unit (seasonic gold 550w) which didnt change the situation and I also purchased a new motherboard (gigabyte z77 hd3) to narrow down the problem.
My original set up was a corsair cx 450w psu, asus deluxe z77 motherboard, corsair vengeance 16gb, i7 3770k processor, wd velociraptor 1tb hard drive and a samsung dvd disc drive
I have removed the motherboard from the unit and have attempted to power it with only the cpu and one stick of ram and the same occurs, a split second fan movement. I removed and reapplied thermal compound, and reseated the heat sink in which I got a the same out come however the fan was spinning in half second intervals more frequently than previously. Previously it would spin and then nothing for another 30 seconds or more. Now I can power it with half a spin and then 5 seconds later another half a spin.
Could this be a problem caused by the registry update, I also have a microsoft heat sink fan, could this be it? Is it really that likely that a perfectly working cpu and ram suddenly becomes broken like this and so quickly, not even 2 years old and purchased brand newp. It was working perfectly before and as I understand if the cpu became too hot it would cut out until the problem was altered. I have narrowed it down to the ram and cpu/heat sink. Any help appreciated!
