I have a client with a brand new Insprion 660 computer, fresh out of the box 2 weeks ago. I setup the comptuer for him, Windows 7 64bit, 8GB memory. I installed all his programs and moved all his data over to the new computer. The computer worked great for about a week, when he called me to tell me that it keeps restarting on him. I went by there yesterday to check for dump files, there are none. There is no rhyme or reason as to the reboot. There is no Blue Screen, No Minidump files, just random reboots with the Safe Mode/Repair Screen after rebooting. They the computer turns on and says the System has recovered from a Serious Error. This happens randomly, no particular software being used, nothing resently installed. The last piece of software was installed 7 days before the random reboots.
Any thoughts, sounds like a hardware issue to me, but running a Dell Diagnostics of course showed no issues.
