The possible reason may be incorrectly installed memory, for example, do not fully plugged in memory module. Otherwise, try to clear CMOS settings (by jumper on MB or by pulling of MB battery for a minute).
Thanks for the above response, I tried to remove all my memory module and ran with a single 2GB stick still same issue.
I removed battery and cleared CMOS setting still no luck
