The main issues others and me have had has to do with the RAM speed. latest current drivers/BIOS won't fix it, but clearign the CMOS might (it did for me):
Clear RTC RAM procedure
1. Turn OFF the computer and unplug the power cord.
2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5–10 seconds, then move the cap back to pins 1-2.
3. Plug the power cord and turn ON the computer.
4. Hold down the "Del" key during the boot process and enter BIOS setup to re-enter data.
*If the steps above do not help, remove the onboard battery and move the jumper again to clear the CMOS RTC RAM data. After the CMOS clearance, reinstall the battery.
