If you want to check the memory, there is the manual way. Take off the cover, if you have more than one memory stick, use only one at a time in the first slot and boot. If you don't get the error with one but with the other, you know one is bad. However, it could mean the other isn't far behind.

Note: if you don't know the ins and outs of digging in, suggested to first ask or to have someone do so.
