Power on motherboard but computer wont start
Just having a few problems, i have recently upgrade my computer by putting in a new motherboard and chip and hdd and videocard!!. So obviously i had to take all the old stuff out!. old stuff being p4 1.7 chip and asus p4 motherboard!. ANYWAY, my mums computer is an old p2 so, ive put my p4 chip and motherboard into her old case!. Ive connected everything up! to which seems correct to me!, but when i plug the power cord in!, a light on the motherboard turns on!, and whn i push "power button" to start it just sits there??. Anyone got any ideas???
Any help will be greatly appreicated
