I used the MB bout 10 yrs ago. Gave my trusty MB to my brother. So I was get GA-990FXA-UD3 up and running again
till I replace my trusty. But now it will not post. I have the correct stuff installed. Got the info from gig web site.
Cleared the CMOS and unplugged all but PSU, CPU, RAM. Fan turns on stays running but no post.
