I just finished building a new pc, but when I turn on the power switch the pc doesn't boot. However the keyboard responds by lighting up briefly (to be specific, the "print screen", "scroll lock" and "pause" keyboard keys light up briefly when I turn on the computer, but nothing else happens). The motherboard is a Syntax S661M with SiS661FX Northbridge and SiS963L Southbridge. The CPU is a Pentium 4, 2.80E Ghz. The processor was inserted correctly. The thermal compound was placed on top of the processor and the heatsink was then attached. The power supply is labelled OKIA420ATX and has 420 watts. There are two DIMMS memory slots, one of which is populated with a 512 MB module. There is a hard drive, a cdr/cdrw drive, a floppy drive, and a modem. I disconnected the modem,the hard drive, the CD drive and the front USB, but the problem persists.
Please help me, I don't know what to do.
