Hit or Miss

I got my computer back yesterday afternoon and this morning it was already not working again. I believe that the second of my two sticks of RAM has gone bad (the computer store determined that the first one went bad, which led to my system locking up and crashing randomly). Unfortunately, with NO working sticks of RAM, my computer will not run. So, a new stick of RAM will hopefully reach me on Monday via crucial.com (because my warranty, lucky me, does not cover RAM).
