A7V problem

Last response: in Motherboards
Share

I think I have a bad mobo but I thought I'd ask for opinions before I send it back. The problem is that after turning on the switch at the back of the power supply my case fans, CPU fan, and HDD spool up but everything shuts down after 5 seconds (the green light on the mobo stays on, however). I removed my HDD, CD-Rom, floppy, and all my PCI cards and still had the same problem. Then I switched power supplies which didn't help. I checked to make sure there wasn't any metal or parts of the case touching the mobo and there wasn't. I even unplugged the front panel power switch lead just in case, for some reason, it was plugged in in the wrong orientation and that still didn't solve the problem. Am I missing something simple? Any help or advice is greatly appreciated. Thanks in advance.

And your cpu is cooling effectively? If you are quick enough, you can go into the bios and check out the hardware monitor and see what the cpu temp is at before it shuts down. I believe the a7v has some sort of overheating protection which turns off the m/b if it's too hot. You must use a good cpu cooler on the AMD's or they don't work or eventually melt.

Also, some people have reported that surge protectors have been the cause of the shutdown.

I assume the silver compound is a heat transfer compound. And the fan sounds like a good one.

If you are quick enough, it would be worth a peek into the bios hardware monitor to see what temperature you are running at.

I also assume from what you are saying, that you can't stay for any length in the bios as it shuts down.

Are there any beeps coming from the motherboard? If so, we could be getting an indication of memory, keyboard or video problems.

If nothing obvious fell out from the above, then I would say take it back.

thats Suppose to happen. Mine does the same. After that 5sec then wait a min. Then press the power button. It should all work.

YEP! The motherboard turm on the fans and stuff for a couple seconds when you first plug it in... I'm not sure why but when the green light is on it means your ready to start dealing with driver problems and not with hardware installation.

good luck!

I had a similar problem if not the same one. I was using a surge protector to cut the power to my system. Even when the power is off the board still has power going to it unless you cut the power using a surge protector or pull the plug. There is a setting in the bios to automatically reboot in the case of a total power failure (switching off the surge protector). Disable this feature in the bios and this problem should go away.
