Hi. I have this old Acer computer, uses this motherboard . When power cord is connected the power supply will start automaticly and there will be no video signal on the monitor nor other signals of life. Pushing power button does not make any difference. I connected an external speaker but it doesn make a sound. It uses a Pentium mmx 233MHz processor. All jumpers where double checked according to the manual but nothing, the AT power supply works OK on other computer. Anybody ?

could be a number of things. power switch (since it turns on the moment power is hooked up), cpu, memory, bad motherboard, you'd have to check each one out. usually by replacing the component, or take it to a shop.

A bad cpu is usually the culprit when an ATX MOBO powers up at plug in. To verify this push and hold the power button for 4 or 5 seconds when you plug it in and it powers up by itself. This should force a shutdown by soft power off. In theory, with ATX, this state should be remembered the next time it is unplugged and plugged back in. If you unplug and plug back in and the system powers up again, chances are the cpu is shorted out to ground somewhere internally and sending a false power good signal back to the power supply. If it doesn't start up automatically then as win pointed out it could be a bad power supply, memory, or motherboard.

You see, this old Acer Aspire used an AT power supply, but without the usual power switch, it uses a different connector with 3 wires Black (ground) White ans Red that conects to a "CN10 labeled as Standby power connector" the way that it appears to be ATX-like power supply, but it is just AT power supply. Hell problem

The way the board is laid out, and as you say uses a modified AT power supply, with standby, I would still suspect a bad CPU. Do you have another socket7 to verify?

I have an Acer Acros with a V58LA board it is old but has sentimental value, I am hoping I can fit
1/ a larger hard drive
2/ possibly change the 166 processor for a 233
3/ fit a CD writer
am I aiming at the moon ????

Many Thanks for any advice
