I have a 2 year old Dell D520. In the last 2 months it is randomly restarting. After hours of calls with Dell support, they claim this is a software issue. Their hardware diagnostics tool marked all hardware components as "good". I also replaced the memory sticks on the box.
I installed a clean OS multiple times (Win 7, Win XP, Ubuntu) and the problem persists. I have one image that was created with a vanilla XP and the recommended Dell drivers. That seemed to work for a short while but had the same issue eventually. Going back to this initial image didn't help.
My main suspicion is heat related failure. But I'm not sure this is it.
Any suggestions for more diagnostics?
Any suggestions to address the heating issue?
If it's restarting from a heat related issue it will have the exact same effect as a momentary power cut. I haven't experienced this alleged stinginess and as someone who runs a repair shop my experience makes me skeptical to this claim. That said, if harlev recently installed a much more powerful graphics card then this could have realistically tipped it over the power edge. Here (http://extreme.outervision.com/psucalculatorlite.jsp) is a power calculator to try to see where the power demands are holding.
