I've just built a new computer and it crashes occasionally - it just switches off and then restarts and I'm not sure about the best way to diagnose the problem. All the components are seated nicely and nothing seems to be overheating, the bios is set to fail-safe. What tools could I use to track down any possible issues?
I've run memtest86+ with no problems. It's running Win7 Ultimate.
Ubuntu 9.10 freezes, although could be some sort of unrelated incompatibility. BIOS screen seems to be fine. I guess I'll probably need to start swapping out parts. – Alister – 2010-04-08T02:16:37.843
How new are your parts? Ubuntu 9.10 incompatibility that would lead to a freeze sounds unusual. And, how long did you leave the BIOS screen? at least 2-3 times longer than your mean failure time? – nik – 2010-04-08T02:18:57.997
All parts are new (Core i3 system with integrated video) I've had memtest going for quite some time without problems - which should be a bit more stressful than the BIOS screen. I'll keep trying various combinations. – Alister – 2010-04-08T03:07:48.633
Does the crash appear after a specific time? Is it always the same time? Maybe your Powersource doesn´t provide enough power for all of your Hardware. – Diskilla – 2010-04-08T06:49:45.600
@Alister: With Ubuntu freezing it sounds like your Windows is 'skipping' a bluescreen and is directly rebooting. Please try this to deactivate the automatic restart: http://pcsupport.about.com/od/windows7/ht/automatic-restart-windows-7.htm
