Earlier I was using Ubuntu version 8.04 and then got upgraded to the latest version of Ubuntu 9.10. This upgradation I have done 15 days ago. From that day onwards, my system gets struck while working. I will have to restart the system to work again. This happens nearly 20 times a day. I have called up my computer technical support person and he has checked the system thoroughly. We are unable to find out what exactly could be the problem. When I was using Ubuntu 8.04 version, my system did not hang. But now, my system is being restarted nearly 20 times a day. Please suggest some possible reasons and solutions to this situation. Looking forward for the valuable reply.
