I don't know how else to describe it, but my computer kind of stalls every minute or so, like it is gathering itself.  I purchased an Inspiron 5150 less than a month ago, and ever since I got it, it has had this problem.  Is this normal???  Everything I read about the 5150 was great; how it is extremely fast.  My hard drive is 80% free.  Just a couple of examples: I can't watch a DVD b/c it pauses every minute.  I thought it was the disc, but I tried many and it still happens.  And when I type, it won't record what I type every minute or so, and then it will catch up after a pause.  It is very annoying.  I would appreciate any help you could give me.

Thanks
