Good day! So, lets get into the gist of it: The system in question is an Asus G71 gx running windows 7 home premium 64 bit. I randomly get bluescreen errors. I have no idea why, since the recurrence of these BSDs have no apparent frequency. Sometimes I leave the laptop on for more than 4 days and no bluescreen, sometimes it hits while nothings running in the background. I must mention that I have not installed any RAM or changed any of the HDD's. Everything is stock, right up to the clock speeds. Out of the brief glimpse I can get from the BSD, it says something along the lines of "PAGE_FAULT_ ERROR" or "Buffer overrun...." "SYSTEM_FAULT...." Doesn't leave the screen on long enough for me to take notes. The temperatures are normal, in load the GPU will do somewhere around 80 degrees celsius. When I do manage to log onto windows: it does say something along the lines of: BC Code 50 and so on. If there is any other information I can give that might assist with this problem, I will. I must mention that the original OS was Windows Vista Home Premium 64 bit. Any help is greatly appreciated, these BSD's are rendering the laptop neigh on unusable.
