I had a power supply fry on my E-Machine Model W3052. Something else on the K7NMF-64 Motherboard Fried as well. I Installed new power unit and have power to the drives and fans. The power light on the front on/off switch will not light up blue and the system won’t boot or beep. Some folks say it’s motherboard….some say its the bios chip while some say it’s the rom chip. Some of these chips are in sinks and can be replaced w/o saudering. Does anyone know for sure wich chip this may be? Any way to tesy the chips?
