hello , i ordered "asus m5a78l-m le" from a site, along with the board i also ordered a "amd fx 4100 3.6ghz" processor , my brother assembled it and switched on the power supply but their was no display on the screen no beep sound ,the light on the motherboard was working fine the cpu fan was also working. i searched a lot on the web so that i can find a solution to my problem , a couple of times i found everybody saying that use a sempron or a phenom 2 processor and update the bios of the board to make fx4100 compatible with the board...so i called one technician so that i can borrow those compatible processors...so i have few questions in my mind, does updating the bios will fix my issue? is it a common problem which i have ? yeah again the same question is it really gonna work???
