I have managed to carry out a system restore which fixed the problem I thought but it did the same thing after the next re-boot.
I have checked the hard drive for errors and it didnt find any, I have also checked the OS for viruses etc. I have norton internet security - no viruses. I have spybot and eiwo - no viruses found.
I ran PC MIghty Max, which found some errors in windows sartup - 7 total but coulndt fix them
I need help fast to prevent format
