Vladd, i already told him that. the BSoD (Blue Screen of Death) will happen when Windows crashes, instead of restarting, it will go to a blue screen and display an error message and then a dump notification. copy down the error message to a piece of paper (all of it) and go to support.microsoft.com and search for that error and most likely there's a solution there.
what Microbell suggested was, when you get to the Event Viewer, expand it, and click on System and look for recent ERRORS. they would have a red mark by them. double click that and read the message and copy it here so we can look at it also.
