I have built my PC a couple of months ago. during the build I already had problems with the RAM, and after changing the order in which I installed the sticks they finally worked. it ran fine for the last couple of months, until now. I just came back from a LAN party this weekend, and suddenly I get Q-code 55. the motherboard manual says this means the memory is not installed. after trying to boot a couple more times I give up. I will have to remove the CPU cooler in order to get to the RAM, which is very difficult(it took me and a friend more than an hour to install it). I can see the RAM is seated properly, however, and everything should be fine. is there anything I can do without having to remove the CPU cooler? I will not be able to do anything until tomorrow otherwise.
