Well, I've had my AMD phenom 2 for over a year, and have recorded an antire album plus many other things with it the specs AMD phenom 2 x3 720 (2.8) 8gb ram (gskill ddr3 1333) windows 7 ultimate 64bit SONAR 8.3 gigabyte mobo 1tb hd (2 500gb disks) Juli@ recording interface ATI XFXforce 4890 1gb video card OK, so the thing is that I've been recently having the horrid blue screens and the system crashes with no previous warning: you're doing anything (from typing in Word to recording in sonar) and everything goes to hell, blue screen and restart. most of the times the message I got was MEMORY_MANAGEMENT this started some months ago, sporadically, but now it's just unbearable, Windows starts and I get problems with explorer, the Catalyst program (from the XFX radeon 4890 video card) and so on so forth, now it's at the point in which I can scarcely do anything except in safe mode I've looked into this, browsed forums, many said that it could be a problem with drivers (I've recently updated the video one to the latest, checked hard drive issues, but nothing). I still have to try moving the memory sticks from one slot to a different one (I've even read someone solve the problem this way) and have also tried removing them, disconnecting the pc and pushed the on/off button. this seemed to work a couple of days ago, and I was able to use it for hours, but then again yesterday I started the system and there we went again... the only hardware change I've had recently was upgrading from 4gb ram to 8 (I had 2 2gb sticks, now 4), but I got the same type, same make, different model though. and some weeks ago I thought THIS was the problem, probably faulty ram (the new one), but after removing them, hell broke loose nevertheless... any opinions/suggestions? has this happened to anyone?? I'm desperate!!
