when trying to boot the pc i got nothing but a whining noise, when looking inside the pc, the display on the abit ag8 motherboard was showing 8.

i read on the internet about cold boot problems and held in the reset button which did make a difference.

switching on the pc i now get


followed by one long beep then 3 short beeps.

heres what i have done.
cleared the cmos using the battery (tried jumpers also).
tried booting up using basic hardware (with out graphics card, hdd connected.

Memory problems,

First try reseting the memory in the connectors

If still the same problem try them one at a time if you have two chips

If only one interchange the connectors
