    Red face Ubuntu 12.04 crash after cleaning computer ...

    Cleaned my computer carefully with aerosol and now it crashes right after loging in.

    How can I rule out if it's a hardware damage? If it isn't I could at least try reinstalling. Any suggestions on how to proceed?

    Here is the link to the logfile of Boot-Repair - which I tried without success:

    Details
    Ubuntu will boot fine up to the login screen. Then - after I enter the password and hit login - it will hang. I am not able to enter anything at the resulting screen (see attachment)

    Running memtest86 from the boot-up program resulted in 0 errors found. Neither, did a check on the harddrives yield an error message.

    It's possible you loosened a connection somewhere, I'd start by checking to make sure everything is securely attached.

    Have you tried booting a live CD or USB to see if that will load?

    Yes, Stoogie, that is from where I launched memtest86 - resulting in 0 errors found - as well as a check on the harddrives. The live CD will boot without a problem.

    Well, if it was me I'd try a reinstall next. If you can save your home folder (including the hidden files), or if you have your home folder in a seperate partition, a reinstall doesn't take too much work.

    Having said that, the fact that this happened right after you cleaned the computer does suggest a hardware problem... but reinstalling doesn't take that long and seeing as all your checks passed, it might be the logical next step.

    Hi

    Can you boot into an older kernel ?

    Kind regards

    Open up the machine and use compressed air--75 psi and really clean it out. The cans just move the dirt around.

    Matt, that worked! I've gotten back into my system with full functionalty.

    Had to go back to a kernel as low as 2.6.x, though. I won't reinstall for now but if I notice unusual behavior I will. Now, is a good time to run a backup on /home.

    (an explanation on how to boot into an older kernel is here:

    Thank you!
