ive had a I3-3225 for about 9 months now and I had a problem with the cpu heatsink fan so a website told me to avoid overheating take out the cpu fan then the cpu the problem was the cord wrapped around the blades and stopped the fan from spinning but after letting the cpu cool and after putting it back in correctly and put the cpu fan on it powers on for about 20 seconds and then turns off as if the cpu isn't recognized nothing comes up on the display either thanks
