my computer is completely new except the mother board, cpu, and ram. I have had no problems for the past 8 months. starting a week ago the computer gives no display and the cpu fan goes right to 100%. I've replaced ram, cleared the cmos, and even changed power supplies. I've checked for swollen capacitors and everything. the only thing I can think of it being is the cpu but if you have any other opinions on what it could be or how to fix it please let me know
