I have a Biostar NF325-A7 motherboard. I put my w4605's mobile sempron 2800 in it and boots and works perfectly. I bought a mobile athlon 3400 64 for the laptop but it runs too hot or something and finally crashes..... So now I want to put the mobile sempron back in the laptop and the mobile athlon in the NF325-A7.....problem is, with the athlon in the NF325-A7 it powers up but does not boot....Any ideas why? The board is suppose to support up to a 3700 athon 64...It is a verson 1.1 with the latest bios...I guess If there is no way to boot the 3400 in the NF325-A7 how do I keep the lw4605 cool enough to run it? HELP!!!
