Had to replace my ECS board with Sempron cpu with a MSI KN 400 MS-7061 mob.\nThe website shows it is capable of handling a AMD Sempron cpu (original\nmanual shows only Athlon capable being the highest). On startup I get no\nbeeps or video. The CDROM and fans spin. Took out my video card and used the\nbuilt-in one, replaced or removed the ram, changed hard drives from SATA to\nIDE or removed mob screws from the chassis and put a phone book underneath\nmob to make sure nothing was shorting underneath. Still no beeps, etc.\nWondering if the bios needs to be updated first before mob can handle the\nSempron. Any thoughts on my problem?
