Run CPU-Z and look at the SPD tab. Find the "667" category (should be the maximum one) and look at the settings. The voltage will probably say 1.8V or some such. Duplicate those settings in your BIOS.
Why in the world would you have a Celeron and DDR3?
Be aware also that many Seagate drives have had serious issues lately. Not that I think that's your immediate problem. I think you are under-volted.
Thanks Proxim. When I ran CPU-Z the small slt test kept stopping after 3 or 4 seconds. The conroe processor was the issue. I replaced it with an Intel E8500 3 ghz processor and the system is running great. I ran the intel burn test and there appeared to be no issues with the cpu. I wonder if the issues are related to an underperforming cpu. I adjusted the Ram as specified with the SPD tab and it kept freezing with the 1.86 ghz dual core conroe processor. Once it was replaced with the other processor everything worked beautifully.
