I am having an issue with my kids computer. I was switching the system into another case when this happened. I had switched everything over and plugged in the machine for the first time. Tada! Everything booted up normally, except for the fact that the system came on without me pushing the power button. Then I noticed that the power button did not work at all. I had to switch the power supply on and off for it to turn off. Oh well, I thought. So I shut the computer down through windows and thought I would figure out the problem the next day. Except now the computer will not even turn on. The motherboard ready light is on, but nothing happens when I push the power button. Here's what I have done to try to solve the problem.
1) Switch the power switch connector to the other direction (about 20 times)
2) Switch power supply to a brand new one
3) Taken the motherboard out and reseated it
4) Reset the CMOS
I have also tested the power supply by shorting out the green wire with a ground and it turns on fine.
Finally, here;s the basic specs of the system
Athlon 3800+ X2
A8V Asus motherboard
Sonata II Case
Thermalke 550Watt Power Supply
1 GB RAM
Geforce 6800 GTX (BFG)
Plextor CD ROm
One more thing, the Sonata case was working fine right before I put the components into it
I need this fixed ASAP as both their and my computers are down and there are things that need to be done with both! Let me know if yopu need anything else!
