I built my son a computer last May, using an Asus IS7 mobo and P4/2.8. For
Christmas I got him new memory, so it's now running 1 GB Dual-channel DDR400
as two sticks of 512.
Sometime overnight the computer stopped working. It was idling unattended
at the time; he was down the street at a New Year's party. When we hit the
power switch, the case and processor fans start running and LEDs come on,
but there is no signal to the monitor and the USB Microsoft Optical Wheel
Mouse doesn't light. There are NO beeps.
I removed and reseated the DVD burner, memory and processor (and replaced
the heatsink putty) with no change whatever.
The only physical symptom is that the fan over the Northbridge chip is
running at irregular speed, as if a bearing were going bad. This is the
first computer I've seen that even had a fan over the Northbridge, but I'm
assuming, since it's there, it must be needed.
Any suggestions?
Thanks,
