this is the first time i've encountered a weird problem like this. it first occurred right after I saved an image on paint, after I named the file and hit "save", my mouse pointer suddenly became sluggish and very slow. After a few seconds, my comp just restarted itself automatically, and then gave me a BSOD error result after the restart. the next BSOD happened while I was playing KOA - Reckoning. I was just listening to a character dialogue and then everything froze, comp restarted automatically, and gave a BSOD error after restart. I wanted to know what might have caused this BSOD problem, so I did a memory test and a hard drive test, but there were no errors. I also downloaded a "blue screen viewer" software that helped me detect the causes of BSOD's, and I found out that it was caused by the file called "ntoskrnl.exe" I do not know how to fix that, I hope someone can help me. After those 2 BSOD's, I was just playing Reckoning again today and was using fraps, and then my comp was completely frozen. There was no automatic restart however, just a complete lockup and it needed a forced restart. Here's one weird thing that also happened. I wanted to change my headset to another one while I was about to watch a youtube video, then right after I plugged the 3.55mm jack into the front panel, my comp restarted right away, and then gave another BSOD error after restart which was caused by "ntoskrnl.exe" again. What the hell was that? What could be the cause of all these? i'm using the latest amd drivers, realtek hd audio driver R267. I'm also uploading my BSOD .dmp files with the "blue screen viewer", and my DXDIAG BSOD .dmp files with "blue screen viewer" software: http://www.mediafire.com/?0rdlh13qdd4p9ke DXDIAG: http://www.mediafire.com/?68os3z5zmx07mm8 P.S. i forgot to mention that i've recently been using the software called sapphire trix to make a custom fan profile, could it also be caused by software?
