a different computer question...maybe someone knows

before you go to dell try a couple things first. You may have a memory leak(not to be mistaken for a rear main leak)..lol Or possibly a bad stick of memory. the memory leak is a little harder to determine so we will go with the RAM . try removing all but 1 stick of memory (dont know how yours is set up) then go play cards or try surfing...nothing too memory intensive-if it runs ok then add another until you hang up again. as you add sticks get more demanding on your comp ...run grafic appz and surf or render a movie (if your into that) and surf . When it hangs undo the last thing you did .and you have forund your bad memory.

Now a memory leak is where a program doesnt release the ram to be reused again. poor programmers are the cause there. use task manager and keep an eye on cpu useage as you play with computer and sometimes you can see a minor app using major resorces

hope this helps
