Old PC wont boot - Lots of beeping and error codes

[chickadee]

So i have an old PC i was trying to get working. Specs:

Core2Duo e6600
EVGA 680i motherboard
8800GTS 640mb
4gb DDR2

So i power it up and get one long beep followed by the LED error code 41 (motherboard error display) and continual short beeps.

Has anyone got any idea what this means as I cant seem to find much.

Its weird because it was powered on and fine for years, i then replaced it with a laptop and now 2 years later it wont boot, nothing has touched it. I will remove the ram/gfx today and reseat them but i doubt its that.
