Asus motherboards are usually American Megatrends' AMI BIOS. and if that's the case four beeps mean System Timer failure: Timer 1 on the mainboard does not work properly. This can mean that your motherboard has failed but before throwing it out there have been cases were the memory has failed on one dimm but not the other, so pull one dimm at a time and try to start it and see what happens

Hope this helps

I'll try this and let you know


one stick of ram didnt work the other did. its new just today so whats the deal. Thanks for the help looks


Found the A channel (a1 & a2) work fine, however, the B channel always issues the 4 beep System Timer Failure code on boot. Anyway to restore functionality? Or is this a permanent failed state?


johngonsalvesjr have you tried more than one dimm of ram or have you tried different dimm. it could be the stick or the slot so try different sticks . also remember that one slot is prioritized as first and unless it has a stick in it the second may not work . also just blowing the slot out may help as dust in the slot can cause problems
