During the Ubuntu boot, if you get to see a Grub menu (with kernel options, etc), can you try to run the Memtest86+ option (that will automaticaly go into a blueish program with lots of information on the several RAM tests it will start to run... and leave it running until it says it has completed at least 2 PASS)
If you have got some bad RAM, it will most certainly accuse (and some how, your Linux host have not been using the faultly address recently) - hardware do crash also... - and the message on Memtest86+ will be PRETTY OBVIOUS (RED CAPITAL LETTERS WITH A BUNCH OF HEXADECIMAL MEMORY ADDRESSES) If you have no bad RAM, with will also list a short 0 ERRORS somewhere in the middled/right side of the screen To exit the Memtest86+, anytime during the tests, just press ESC, and your computer should reboot (and hopefully back to OS) If you do have a faulty RAM, try removing a DIMM (that are the name of the RAM boards) a time, and test the rest again until you are sure there ones installed are fully operational... you might need to buy another RAM if you do find any broken ones 2011/11/23 Serge Hallyn <[email protected]> > Quoting [email protected] ([email protected]): > > Dear all, > > > > On one of my windows Vms (KVM), I get from time to time a 'windows > > recovered from a serious error' message, and if I click the wonderfully > > useful (ahum) support link, I reach this page: > > > http://wer.microsoft.com/responses/Response.aspx/1445/en/5.1.2600.2.00010100.3.0?SGD=67dba5c9-dc73-4bb8-8065-512ebd1c74ac > > > > I quote the first part of it here: > > > > "Consider BIOS upgrade > > > > Microsoft is unable to determine the exact cause of this error.
