My Desktop PC running Windows 7 on Intel Core i3 dual processor machine started shutting down during the boot process a couple of days ago. I left it alone for about 48 hours and tried again. The boot process informed me about Processor Thermal Trip as being the cause of boot failures and suggested a Windows recovery process. I went through the recovery process which completed without problems. The PC booted normally and Windows 7 worked as expected but after 10 minutes it again tripped and now whenever I start it, it shuts down during the boot process.
What should I do next?... is there a boot menu / setup settings that needs to be adjusted to avoid it... Or is there a hardware problem (which seems unlikely as the machine occasionally boots perfectly )?
UPDATE: Thanks folks for the help . I wasnt confident enough to mess with the PC myself so I took it to my dealer. He fixed the issue. Below is my answer. Each one of your answers/comments have some truth in it.
