About a year ago I put together a computer on a Soyo SY-K7V DRAGON motherboard. While it's never really performed badly, it's had alot of wierd issues.Until recently, for example, it refused to start every other time I hit the power button. It didn't bother me terribly because it always came on the second time I hit "on"From the begining, the onboard Ethernet adapter never worked. Recently it started working again. Not it's cut off again and I've had to reinstall the network card I had been using from the begining.Also recently, the onboard sound adaptors have decided they want to install. I've done disabled that as I have a Sound Blaster Live card I prefer to use.All these changes happed right when I upgraded from 98 to XP. So I figured "okay, it's an XP motherboard. No big deal". And just shrugged off the whole thing as a learning experiance.However, the Ethernet adaptor cut itself off again which I mentioned earlier. It's installed and working okay according to XP. But... it keep saying the cable is unplugged. It's obviously not the router or cable because plugging it into the freshly reinstalled Netgear network card has everything working again.Just alot of odd things. I can't help but wonder if this is just a Soyo motherboard trait or just the signs of a not quite nearly adept enough user

It may be Soyo and it may not. I've heard a lot of mixed results with this board, but I got a good one. No on-board LAN problems, no restarting problems.

 

If you want to keep using it, just use the ethernet card and put up with it as long as you can or will. Or you could try adding a PCI ethernet card and not use onboard. You can get a cheap one online that will work fine. You can always check the Soyo section of www.amdmb.com forums for more info on this MB.

Make sure your onboard items are disabled in the bios.Disable everything you do not use. Serial ports, Printer Parallel ports, NIC, Sound. Make sure you are saving the changes as well.When possible. Point the installation to the driver. Goto device manager and reinstall the driver or upgrade it. Do not use the self install utility. It helps.

Update your VIA, SIS, Nvidia or others drivers of the motherboard (Check the manuel to know which are use)Look in properties of your Ethernet adaptator if Windows don't shut down it when you don't use it for few minutes.Look in google if noone have same problems like you.And like Macgyver said disable everything you don't use in the BIOS.

Update the 4 in 1's or now called Hyperion Drivers. www.guru3d.com has version 4.51 under Via chipset driver.

 

Get the latest NIC driver from Soyo's website if you want to try the onboard lan card. Also try different PCI slots for the sound and NIC.
