Asus maximus vi hero post code 55

About a month ago I put together my first build amd everything was working good. Yesterday I wanted to re do my thermal paste. So I got that done and put everything back together now when I try to power on my computer I get the post code 55 and the dram led is solid red. I didn't even touch the ram when I was doing the thermal paste. My monitor doesn't come on either. I followed the manual about clearing the cmos with the jumper amd I did that. I also took out the battery and that didn't help either. Before today everything was working fine. I could really use some help guys.

I didn't take the cpu out at first. After I tried to boot up and got the error code I took the cpu out and checked for bent pins. I didn't see any so I put it back in. I'm pretty sure I put it back in the right way. I'm at work right now so when I get home I'll check again. I'll also post my specs when I get home too.

Can anyone think of anything else?
