About a year and a half ago, I built a new computer. It has been as solid as a rock until two weeks ago. At that point, a suffered I nasty crash which including screeching sounds from my speakers until the computer automatically rebooted while play a game of Diablo 3 with some friends. I could not reboot the computer until I ran windows repair from the boot menu, and I had to run windows repair twice before I could get the system to run again, as my first attempt resulted in an error. Upon rebooting windows recognized their was a problem and reported it as a video hardware error. I have since updated to video drivers but that failed to rectify the problem. This time windows crashed while play Dishonored. I was able to enter task manager, but before I could select end process on Dishonored the machine froze with a black and white pattern of streaks on the screen. Again I needed to run Windows repair from the boot menu. Again my first attempt at repairing Windows failed, this time with a bluescreen displaying decimal hex. After the first failed attempt, the machine would not even boot past the BIOS screen. I had to turn the machine off for a minute before booting and running Windows repair, which successfully brought the machine back online. At this point I am considering replacing the video card, which is unfortunately a very expensive component. However, I was hoping someone could help me better understand what is going wrong before I dump $300 on a new video card. System Specs: Motherboard: MSI X79A-GD45 Processor: Intel Core i7-3820 RAM: 4 GB DDR3 Video Card: Radeon HD 7870 I have attached a minidump file from the first crash in a .zip extension as well as a data file associated with the second crash. Unfortunately, the second crash did not generate a minidump file. If you need more system information, please do not hesitate to ask. Thanks for the help.
