:disgust: I have had lots of problems with the MSI K8N Neo4 Platinum and i wholeheartedly suggest you go elsewhere. my biggest problem is random reboots about every 4 days for reasons that have eluded me for more than 3 months. all the parts listed in my sig below are new and i have updated the drivers to everything and the bios to the latest 1.5 version, and still no go. when it restarts it no longer can 'see' the ide drives (CD-RW, DVDR, PATA hard drive), and will only come back to life if i hard reboot. my working theory here is that something blows up, causes the reboot, and upon reboot the bios doesn't reload into RAM as the bios sees the corrupted one that's there and thinks it doesn't need to reload. another symptom is that occasionally i'll hear a click from the box (like a small solenoid), and the machine freezes for a few seconds and then works fine. it has only crashed twice in my presense, so i have an annoying lack of data on the problem, but from all the work i've done i can tell you it just shouldn't be happening. my other 3 machines all work great and are stable.
problem two is that it restarts itself after i power it down... i don't get this one at all.
the MSI 6600gt i have (which i bought from the same mfg as my mobo to hopefully insure compatiblity) ships with drivers that if combined with directX 9.0c and the game XIII (which is bundeled with the card) actually crashes to the desktop if you try to play it... this one blew me away... the software that the firm ships with its own card crashes. nice testing there i'd say. these are my three major issues.
problems that i've read of but not experienced: is that the nvidia ethernet port is reported to be quite buggy as if that isn't enough the the nvidia firewall is full of system bugs as well. consequently i have the nvidia enet port disabled in the bios and use the marvell enet port.
i have overclocked nothing and run everything at its stock speeds and specs. i have no interest in oc'ing. i place too high a premium on reliability.
in short, i hate this mobo, and my sence is that it's a bios or nvidia chipset driver problem, but i don't have a firm answer as to what's wrong. all i know is i went to a lot of trouble to buy higher end stuff to insure reliability, and all i've got is a headache.
