Just built a new computer from scratch. Installed a mach speed matrix pm9ms socket 478 motherboard, on power-up the system gives no beeps (post boot). nor any video. (intergrated video) Motherboard does have power, because the processor fan works, maybe i missed something when i put it all together?? Jumper Settings perhaps?? any ideas?? PLease help, oh one other thing too, the led for the hard drive stays lit solid on power up, no flickering.
