Hi, I am a college student who's laptop, which is the key to my higher education and homework and communication seems to have a few bugs. It runs fine for about 30-45 mins, then out of nowhere a blue screen popsup and says something like windows has encountered an error and needs to shut down. It says something about memory problems and then my computer restarts before I have a chance to copy down what it says. Can you help me, this problem is pretty annoying. Vista.
