Why won't it boot?
Ok so I was just going about my business paying some World of Warcraft when out of no where I got an error window then my laptop crashed and won't boot. I couldn't see what error because it crashed before I could get a good look.. but it was one of the 0xc00000XX errors. I unplugged all usb devices took out the battery and ac adapter then held the power down for about 1 minute then plugged only the ac adapter in and it powers up with no display and I did try hooking up external monitors at both AVG and HDMI ports. I've also done all that but changed the ram with my other laptops ram and then turned it on but still have the same issue. the fan also starts up on high and my laptop gets pretty hot.
Edit: I can get into the BIOS by holding shift down and power button down for about 5 seconds. out of the BIOS I still have the same problem.
Edit 2: I ran a diagnostic on it through BIOS menu and it said everything was perfectly fine. after that I still had the issues but I had kept messing with it turning it on and off and it's booting up properly now. If it does it again I'll screen shot and post more details.
