I'm having a problem with my laptop. It has been rebooting automatically without prompting. I have ran the Windows Memory diagnostics tool and have found no problems to report.
I have read that a possible cause could be faulty RAM or a power supply. I did a complete system restore about a month ago but this problem has been occuring in the last week.
Could my problem be RAM, power supply, virus, malware or other? I'm really not sure what else to do. I have done a complete virus scan (AVG), used SpyBot and AdAware, CCleaner, Smart Defrag and Registry Cleaner.
I have also ensured that my Windows Vista Home Premium is updated and allowed ZoneAlarm to operate using the recommended settings.
Can anyone suggest what could be done to prevent my laptop from rebooting on it's own?
