I have an "older" Dell (2010 model), when I start the computer up, it loads the BIOS, shows grub, but when I try to boot into Ubuntu, Recovery or Memtest it dies. I should also note that the grub display looks funny, not that nice ubuntu purple shade but white and black.
Background: Last night, I was working away on the computer, and "a" fan (I don't know which one) started going like crazy, given that I wasn't doing anything to push the machine (I'm a data guy, so sometimes - it gets maxed crunching numbers) I thought this was strange. It continued for a little bit and I figured it was a loose process or something of that nature. So I shut the computer down, normally. Now I can't get it to boot back into the operating system.
Dell Vostro i7-860 8gb ram Diamond ATI hd5670 Ubuntu 12.04 (Not dual boot)
Troubleshooting advice greatly appreciated.
- I'm able to load the operating system without issue. Seems as though it was just a significant build up of dust.
- I opened the box, and began a thorough dust removal. There was a significant amount of dust on the primary heat sink. I am now able to perform memtest.
