PSU Fan Running High/CPU Fan running high at same time

HP Recommended
HP 705 G1
Microsoft Windows 10 (64-bit)

When I go to turn on my HP 705 G1 Desktop, the pwoer will turn on by I will not get the normal post. I will not see the keyboard, optical mouse, or vga get signal. I do not even see the HDD indicator LED flash like its booting. What happens is after about 7-10 seconds the power supply fan will start running high and the CPU fan will run high concurrently. They will keep running if you leave it on. Once in a blue moon when restating it, the machine will boot and power on. Ive gone through a RAM test, Reset the BIOS, pulled the CMOS, checked the RAM modules, check my capacitors, and swaped RAM sticks and nothing. The green lindicator light on the motherboard is showing it is getting power. Is my power supply going bad?? I am wondering why both fans are running high at the same time?? Please help me an I dont think its the motherboard but at the same time it could be. PLEASE HELP!!!!!!
