BSOD WHEA uncorrectable error

Hi all,

I am facing with the BSOD (Whea uncorrectable error) issue with my Optiflex 7060. It only occur after I plug dual monitor to the system. Strangely, it occcur only in the morning, a few minutes after I start up the computer. After that, it work fine during the day. I have update all the lastest BIOS and Graphic Driver. The error still occur. 

Do you have any idea for this problem?
