this morning i was deep into p5 grouping when POP!... reboot... i dont know what happened but when i typed in my pw to logon, i found my keyboard was fried... what makes you so sure poser is at fault and not just faulty ram chips or some other config problem? a blue sceen can mean several things. was it a ram related error? post it here then, so others can see. what os are you using? maybe you should just get new ram chips if is indeed a ram issue. my guess is its probably a combination of not enough memory and fauly (insert technical name here) for you to get a blue screen. which, again, can mean a few things so if is a ram error, get new ram and see if it helps. there is such a things as crappy ram no matter how expensive it was when you bought it. hope things work out. we need p5'ers to keep working at it. its hard to find/fix the issues THAT are program issues while filtering out the general computer stability/capability/compatibility of all the different specs out there when people with problems dont share them aliong with their issue.
