Stuff happens.
I have two EPOX's, 8RDA and 8RGA+ and love them both.
Just because you got a bad one don't jump the EPOX ship because they make a fine MB. A while back I ordered a SOLTEK and it was dead as a door nail so I RMA'd it to newegg and got anew one and it worked slic kas a whistle. Reason I went EPOX is because Soltek pulled their support out of the US to Taiwan. Who lnows why we get bad MB's? Maybe it was mishandled during shipping which is no fault of the MB maker. They all have to pass quality control tests and I doubt they put bad MB's in the box to ship out so something must have happened to cause it to malfunction when we install them.
Whatever the case, please give EPOX another chance because I'm sure you'll be very happy with it. One review said, "EPOX MB's have an almost "cult like following" and I agree.
When you hear the beep that simply means the BIOS is happy with what it sees and everything is up and ready to run and the beep means the BIOS is turning control of the computer over to the OS. The beep lets us know the BIOS chip is working and the comonents, drives, etc. are all present and accounted for. Simply put, the BIOS is the Drill Sgt that wakes everybody up and makes sure they are all there ready to go work.
