Unusual computer

Today I came across a very interesting computerAccording to the hostess, he stopped working, loading. I'm not special, but I know that this can be due to problems with RAM.There are two DDR2 slots, one of them seems to be creating a problem. I had to remove the memory from this slot, but with two gigabytes the operating system now works fine.After turning off the network, time is lost. So you need to look for where the battery is.Everything is not very convenient, but I still got to it. )The battery, as in laptops, was replaced by a regular computer.Another hour and a half, and I collected this miracle.Everything works, tomorrow I'll go confuse the mind, is it possible to put more memory there. And also let them see what is with the slot for RAM.
