I'm sorry if i have put this in the wrong forum area but i didn't see anything for crashes and other problems like that. i will now try to explain my problem as best as i can. I have just received my graphics card back from Scan.co.uk as i thought i had a graphics card problem. I then installed the card and put it into power saving mode using ASUS EPU-4 ENGINE as i was busy at the time and when i come back 30 minutes later my screen had turned off. So i then tried to wake up the screen by moving the mouse but nothing happened, so i had to hit the reset button on my case. This then gave me 8 beeps from my internal speaker and the screen also never came on, so i therefore had to hold the power button to shut it down. I then turned it back on after 1 minute and everything worked fine until i played a game (Total War: Shogun 2), which i managed to play for 1 hour before it then did the same thing and shut the computer down. I have now looked on my Reliability Monitor to see what caused this and showed me that i had a Dump file which i have attached to this post. Any help at this time would be greatful, Thanks.
