iMac won't boot up at all, fans running at full speed only.

My 2006 24" iMac simply refuses to start, all it does is the white LED turning on and the fans going full speed immediately after pressing the power button. No boot chime nor screen turning on either.

I'm not sure if I can reset the PRAM with a Windows keyboard, since I don't have an Apple keyboard in my possession.

Any other suggestions?
