It does sound like a heat issue but just putting fans in the case may not help. It really sounds like the Processor is overheating. So check the fan on the heatsink, make sure it is working, spinning, and try blowing out the fins on the heatsink.

Do you remember what all you touched when you installed the fans? You could also have accidentally loosen something in the process. Does it boot up, and then shut off, or are you hearing a beep sequence?

no i haven't, it turns off when windows is loaded and i start a program or something and i changed the psu and it worked after.

the fans are only able to connect to the power cables(hd)
I will probably buy a new heatsink/fan.
