Based on the problem description and troubleshooting done so far, I'd recommend the following:
1. Restart the system into BIOS by pressing <F2> during the boot process. Once in the BIOS setup utility, press <F9> to restore BIOS default settings. Reset any customized BIOS settings. Clear all DMI event logs by setting the option to "Enable", which is located in the Advanced/Event Log Configuration section of the BIOS Setup utility. Press <F10> to save the new settings and reboot the system.
2. If the problem continues, see to it that your memory is 1.5V. This is very important.
Also, see to it that your OCZ* memory is shown here:
