I just built a new system and the hardware seems to be fine. However, when I installed Vista, both 32 and 64 bits, I get random BSODs and crashes. I just reinstalled 64 bit today and while I was trying to upgrade to SP1 (from the downloaded file) the computer crashed. I tried using Windows Update to update, but there were more BSODs. I've attached all of the minidumps from the crashes. Please read them and help me figure out what the problem is! In addition, there are random problems with Vista. These errors do not always occur, but some include Task Scheduler Engine and Windows Defender User Interface have "stopped working" and Windows Modules Installer ran into "CbsPackageServicingFailure". Microsoft says these problems can be fixed by updating Windows, but updating Windows is a problem in itself! Oh, there are also random BSOD crashes, some with the title "Memory management", yet I've ran Memtest multiple times for 6+ passes and there were no errors. I've checked my Western Digital 640 GB HDD with the WD diagnostic tool and saw no problems. All the minidumps of the crashes are attached, so please help me read them!
