i have a fairly new pc i brought from dell. I take it to and from my office and lately i have errors on start up, saying my memory has changed from 1024 to 512, i just thought the ram was loose but then it started saying something about the drives d e and a i dont know what about i think it was formatting or them not being their???? its doing my nut. i looked inside nothing wrong i can see i took the ram out, then put it back in it worked fine. then i started it back up days later and the same again system memory change then the same thing with the a d and e formatting thing. ahhhhh!!!! can it be something to do with loose hardware thats the only thing i can think of as its being moved a lot. if so what do i do.
