Not trying to be smart a$$ but you haven't accidently unplug any power leadss from mobo? I bet the answer is no
but you could check em just in case ![]()
after adding a 512 ddr ram with my old 256 stick my computer wouldn't boot at all. no fan no nothing period, ive asked around for help and most people said its my power supply or mobo, however when i turn on my PSU switch a green light turns on on my mother board
its a soyo case and a soyo mobo.. i know double trouble .haha
ive tried taking out both ram, and seeing if it starts without ram, still wont work. I tried just leaving the 256 in , wont work.
