After turning it on nothing comes on screen. Then after 15 seconds you hear a loud beep that lasts for 6 seconds, 6 second gap then another loud long beep for 6 seconds. The mobo is a Gigabyte 7VAXP, ram is generic pc2700 and grfx card is a gf4 mx. Which is it, the ram or the grfx card? I dont have any components on me to swap and see. Cheers.
