Okey so I have a gigabyte ga-h110m-a and I had 2 4gb ram sticks in there. I decided to upgrade my ram so I unplug the ac cable from the psu. My eps cable to my CPU is in the way so I unplug that then go on take out the ram. I put in the new ram and then plug the eps cable back on. Plug in the ac cable and turn the system on. My screen stays blank saying no hdmi signal my fans and gpu turn on for about 10 seconds then shut off and restart in like 5 seconds. I've tried switching the ram spots. Removed the cmos battery. I've tried many things the thing that grabs my attention is that I try to start my system with the old ram and the same thing the fans and gpu turn on and off. Even though it was working yesterday just fine. So now I'm not sure if I messed up my mobo or my ram is compatible which I'm sure it is because I made another thread about it and they said it was compatible.
