I am currently running a a ABIT kt7 mothboard with a duron 850 everything is working perfectly.

I bought a Aathlon 1.3, I installed it and NOTHING, no video, no mouse, no keyboard , no boot up.. I take it out and re-install the 850 and everything is good again.

DO I need to clear the bios and then boot up?? everyone says the athlon 1.3 should work and it worked when it was pulled from my friends system.

any answers???
