So, I went to travel for 2 months, and I unplugged my computer from the outlet, turned off the psu switch and unplugged everything else. Now, 2 months later, I came back, and as soon as I tried to turn on the computer, the fans went full speed mode (something that has never happened before), and my computer was damn slow, never had this issue before, so 5 mins after I got a blue screen, and ever since I couldn't manage to turn on the computer. I managed to get into the BIOS and it says my CPU temp is at 100 celsius, which is weird because it never got this high before, so I went ahead, and reapplied thermal paste because I thought that could be the issue, and still, I get the same issue. Whenever my computer turns on, all the fans go full speed, and 3 mins later it shut off. And just to make it clear, none of this has ever happened before, I built this computer almost 3 years ago and never had any issues with it.
Here are the specs if it helps:
i7 4790k not overclocked
z97 Gaming 3 motherboard
Corsair CS650M PSU
Corsair H110i water cooler
MSI GTX 970

Any of you guys had this issue before? Any help would be appreciated, thanks
 
try to boot to bios and look at fan speeds, does the CPU FAN/PUMP register as spinning?
if not that would be your issue. if it does (should read about 1000-1500) the fans your hearing are case and video fans.

Other things to try
-reseat your video card
-reseat your ram (pop them out and blow air in slot and put them back in)
-I would gently remove the cmos battery from the motherboard while your computer is unplugged from the wall, wait 2-3 mins and put it back, apply power and turn it on does it boot ?

Fans are spinning. But BIOS doesn't recognize them as spinning.
radiator fans are on, but the motherboard doesn't see them, only the system fans.

Removed the video card, reseatted all of my ram, and removed battery and put it back in, issue still remains.
