I got the computer in 2009. The power supply is something i didn't think about. so I will look into that. I had a CPU fan issue a little while ago and had to replace the fan/heat sink and the CPU may have over heated. other wise CPU would be at the bottom of list of suspected problems. - Andy <div class="gmail_quote">On Sep 6, 2014 10:14 PM, "Chick Tower" <<a href="mailto:c.e.tower@gmail.com">c.e.tower@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">On 09/06/2014 09:58 PM, Andy Ball wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Looking for some help and tips. I am currently running Ubuntu 12.04 (64bit) I am having some crash issues lately and suspect Hard drive or CPU issues are there tools that are recommended to help identify what the problem might be. Not the best with command line so graphical tools are desired. I am looking at upgrading from 12.04 to 14.04 I leaning towards fresh install. My main concern is keeping Virtual Box machines from breaking most of them are on an external drive is there something I need to be aware of and back up. </blockquote> If you're worried about a hard drive failing, Andy, check out smartctl and smartd. I don't know of any GUI interfaces for them, but they're what you want. How old is the problematic PC? I thought I was had a failing video card on my eleven-year-old PC, but a replacement video card didn't make any difference. Later, Bill Marr suggested that it might well be the power supply, which I now suspect could be true. I replaced that PC, though, so I'm not going to spend any more time trying to figure it out. But, depending on your symptoms, if there's any reason to suspect the power supply you might want to find out how to check that out or how to replace it. In my case, the PC would suddenly start the boot process, with no shutdown beforehand. -- Chick _______________________________________________ linux-user mailing list <a href="mailto:linux-user@egr.msu.edu" target="_blank">linux-user@egr.msu.edu</a> <a href="http://mailman.egr.msu.edu/mailman/listinfo/linux-user" target="_blank">http://mailman.egr.msu.edu/mailman/listinfo/linux-user</a> </blockquote></div>
