Hi, I've been getting freezes and blue screens pretty regularly on my PC for at least a month, mostly while gaming, but only windows 10. I have no problem running linux, but running netbeans isn't exactly pushing my computer to its limits... All I can tell from looking at the dumps with windbg is that it's always "Probably caused by:" a system driver. I put windbg's output for the last blue screen on pastebin (http://pastebin.com/ZZ6MJhJu) if you want to look at it. A couple weeks ago I had a gut feeling it was the hard drive, so I downloaded seatools (it's a seagate barracuda) and ran the long generic test, it failed with a couple of bad sectors. I used the bootable iso to "repair" them, and I still have freezes, but seatools doesn't find bad sectors anymore. Could it still be the hard drive? Note that the games that make it crash more often are very large (60GB and 25GB). I ran memtest86 for like 1.5 hours and I came back, 1st pass was complete with no errors. I don't think it's the graphics card, when my GPUs failed they usually overheated very quickly. All the temps are good, always under 50C under load. As far as I know, the only way to test motherboards, PSUs and CPUs is to swap them, obviously that's not an option for me, but if I bring it to a repair shop, will they be able to tell me without a doubt what I have to replace? Money is very tight right now.
