Hello,
I have a new system that has been nothing but issues.  I have an 890gpa-ud3h with 2 adata s599 SSD's in raid 0.  I have 2 2GB OCZ 1333 mhz sticks in both blue slots.  I had to change the timings of the memory and increase the voltage to 1.65 in order to get the system stable.  I also had to update the firmware of the SSD's to get the sleep mode issue fixed.  Now, I can run the system at 100% load for 14 plus hours with absolutely no issues.
However, if I shutdown the PC and let it sit for a while it will act VERY VERY strange on startup.  I would get all sorts of errors.  Programs would reset themselves.  Windows Essentials would stop working, etc.  If I pull the power plug for a while and then start it up, it runs forever again with no issues.   The reason why I think this is a motherboard or configuration issue, is that I have a 3 1/2" card reader that has power lights on it.  When the system runs well, these lights will light up as soon as I start the PC.  If they do not light up, it acts odd and will error on something or another.  
Has anyone ever seen this sort of thing?  I have been trying everything I see regarding CE1, and anything else.  
Thanks,
