|What went on before this ? |
Was the computer working fine before step 1 ?
You DO NOT try to update your bios when the computer is NOT working properly !
"I removed memory modules, then inserted 1, (3 beeps) then 2, no problems with memory. "
If there was nothing wrong, unless, possibly, if you have DDR3 ram, you will hear only ONE beep while booting when at least one module was installed .
