well ive singled it down to the mobo its self, ive tryed pc 2700 and pc 2100 ram and ive tryed various between 1 gig to 256 and minimal 64 and yet no progress, it will boot to the evga logo from the mobo and then shutdown, im guessing it shuts down because it is trying to save my hardware. so i had my friend try my ram in his computer, it works fine, so imma go to tiger and buy a new mobo and try it then, but i dotn see why my mobo currently used to boot up, and now it doesnt also will newegg exchange or give me my money back if i RMA it? for faulty dimm slot?
