Answers :

I recommend against running for more than a minute or so without the fans.

\015\012Last time I had to replace a fan I had to replace the power supply. Perhaps talk to your hardware parts supplier and see if you will need to replace the power supply.
The first thing I would check is the power supply. It sounds like it has just enough power to turn on some lights, but not enough to power up fans, motherboard, CPU, etc. So either test the Power supply, or just purchase a new one. They are pretty cheap these days.
