You have memory problem, Try either setting a lower divider for the ram to slow it down to stabalize it, or take your PC to a local pc repair shop and see if they have a EuroSoft PC Check disk to run diagnostics on it and they will be able to tell you exactly what the problem is. (They will probably charge a bench fee)...That is what I would do, because that is what it seems like you have a problem with!
