Hi there:

I built my Athlon 700M home PC about 2 months ago with Abit KA7 mobo and 100pc 128MB DIMM RAM. The OS is Win2K and Win 98 dual boot. Everything worked fine until this afternoon. It failed since my 1st try although it was a normal shutdown last night.

The power light was on green, the CPU fan was working, but there was no beep and monitor was blank and HDD light was off. In addition, I can't turn it off with front power switch. Then, I removed every components, just leave CPU and power lines on motherboard, after I turned power on, same results: the light was on green, the CPU fan was working, but no beep and I can't turn it off from front power switch. Does anybody have any idea what's wrong with my system?

Thanks in advance for your help.

Water.

Had the same symptoms on my self-built AMD K6-450 system after it worked flawlessly for months. Power light on, fan spinning, nothing else happened. Turns out my old power supply was just about gone - only had enough juice left to do that little bit. Installed new power supply and my system booted right up and has been fine ever since. What size power supply are you using? With Athlon systems, I believe at least 300W Athlon-approved PS is recommended.

Hope this helps... http://www.PCGuide.com/ubb/smile.gif

Could also be bad memory or CPU got overheated and went bye bye. Check the video card to be sure it's plugged in securely. Bad BIOS chip might also cause it, not positive. No beep says something is bad wrong...before POST finishes.

I believe it was short circuit problem. Jerkymom's information leads me looking into my power problem more closely. I found it out from this website that the problem caused by short circuit will cause the same symptoms. Hence, I removed all screws from my mobo and tried to reboot with CPU, RAM, AGP, FDD only and POST was up fine. I went to Sears Hardware twice today to find out good nylon screws for my mobo. The system was rebuilt and it is running great now.
Thanks for help.

For future reference, if you check this post again, you can also get plastic or cardboard washers from computer shops that are designed to do the same thing. I've had to use them several times to remedy ground problems between the motherboard and the chassis of the case.
