Hello guys, I need help whit my motherboard , 
this is my first time getting a Gigabyte motherboard , 
I have the GA-890GPA-UD3H Model . 
a AMD 965 x4 Phenom II black edition , 
Ram Corsair XMS3 DDR3 mod # TW3X4G1333C9  like the one below 
http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=4505190&csid=_21and 2 sata HD GB gigas each one identical 
the problem is the  can't install any operating system    XP, VISTA, or 7 
the installation stops or freeze , and nothing happen , just still like that installing or formatting and never finishing , 
I try just whit one hard drive , y exchange HD . change optical drives ,  
I disconnected USB , speakers  etc ..  and nothing change 
I try using a RAID 3.0 or 3.1  or just regular installation and nothing 
I don't know whats wrong ? 
some friend say is the RAM .and I try using just One at time and replace one for other.. and  the same happen  
probably the ram is not compatible whit this Motherboard ! 
but before i want to now before expend another 100s for another RAM model  
Any Idea whats wrong ?
