Today I brought a New Mother Board (ASUS M5A78L-M LX) for My PC. Then onwards my PC is not booting. It is sowing My Processor Model, RAM, Hard Dislocated etc on the top and showing some thing like press 4 for Activation F8 for Bios Popup and CTRL+F2 for flash bios. And at the bottom it is showing a message as it is going to shut down in 15 sec and Turning off. It is also not opening bios settings when I'm pressing DEL key not only that it's not responding for any key except Flash Bios Key CURL+F2 it's showing.
As I mentioned above my new Mother Board is ASUS M5A78L-M LX old one I used was ASUS M2N68-AM plus. My processor is AMD X2 440 triple core processor, I've installed 2GB DDR3 Ram and segate 500 GB serial ATA hard disk. This is configuration of my PC can any one help me in solving this issue.
I'm also thinking to upgrad my RAM to 6 GB can I install 2+4 GB on my board?
