ok hold the power button in for over 10 seconds it should switch off

sounds like it could be the processor... but motherboards cause issues like this too unfortunately.. your in the luck of ebay im afraid.

Ya thats where i bought them both,also the power button doesnt respond after the sys is running even holding it for 30 sec, I have a question for you why do you need so much storage space with that many harddrives.

mmm, lol i sometimes wonder my self..


I run my own computer business and data recovery is onething that i do hence i have customers data on some.

The rest i use to make DVD's from various image formats for various customer requests.

I believe it or not both my 2gbs are a 3 quarters full each i have just ordered another two to back this lot up on.

I have also got some developement work, image files, personal files and loads of music.

I can fill a TB hard disk up in three months :)  with various files, edits and file images that i have. I have ghosts of customers hard disks too.

Well i got the new cpu's and still have the same problem so I'm guessing that the motherboard has something bad on it, so all that was just a big waste,I should've bought a new board an started over but I wanted to fix what I had. Now I need to know what is the best board in a socket 754 that will accept an ATHLON 64 3200+ I like the way they run and want to stay with it but not sure which board will hold up the longest I have tried BIOSTAR and ECS an neither lasted 2 yrs. Any suggestions on what board would be the best for me to buy.

Its not the case of which one is best, its what one you can buy

Socket 754 motherboards have been EOL for over 3 years now,

http://www.lambda-tek.com/componentshop/index.pl?origin... is one place i found

if your in the US google for a socket 754 motherboard, or try ebay.

They just dont make them anymore, I have some Gigabyte boards in stock and those and ASUS are the best there is.

Good luck in finding a replacement but it might be time for an upgrade !!!

You can upgrade to a new quad-core AMD system for $300 exc. GFX.
