Question

if an error occurs before the single beep tone in the bootup sequence what type of failure is probable

Answer 1

DRAM refresh failure (see AMI BIOS beep codes). The system is having a problem accessing the system memory. Refreshing is done on all system memory to keep its contents active. It usually means a problem either with the system memory or with the motherboard itself.
