thank you for answering andrew. this machine is only 1 month into a new gigabyte motherboard shop installed, so I would assume that it would be the latest bios. It was running perfectly until an automatic update required a restart and failed to boot properly since then. I had windows 7 shop installed and ubuntu dual boot. It proved problematic until I got rid of win7 and is now solely ubuntu.The motherboard fitted is gigbyte GA-F2A68HM-DS2. the chipset is AMD A68H with onboard graphics.I hope this information is usefull. sorry for being so tardy in replying ,but us old luddites need our sleep
