Hi guys im new to this forum, i have a major problem. After inserting 512mb DDR RAM into the DIMM sockets .My PC starts but i dont dont hear any bleeps, the fan is working it regocnises the mouse, keyboard becuase it lights up but the monitor screen just turns black, if i remove the monitor cable it says no signal on the monitor. But as soon as i insert the monitor cable the monitor just switches off. If im right when i start up the machine i should get a single bleep sound but i dont. i have removed the DDR ram and inserted another one, i have also purchased a monitor cable to try with a new monitor cable. But still no luck. Also tryed removing the graphics card and re-inserting and also tryed removing the graphics card and starting the machine, when i do this the machiene should bleep several times to say there is no grpahics card present but it doesnt.
