Hello all,
My computer is rebooting by itself, probably about every 10 or 15 minutes. Any thoughts how to go about fixing it?
Latitude e6430
Windows 7 pro
i7 processor

Thanks for the help

Fan turns on, everything is clean inside, all vents are clean. I have tried system restore back as for as I can go, it did not help. One thing, I no longer have the integrated Intel HD graphics, I am using only Nvidia now. Could this be the problem?
Thanks for the help
