Sometimes my machine has a mind of its own and it reboots spontaneously. It happens randomly (sometimes 3 times a day and sometimes it can take some 5 or 7 days before it happens again). No difference between idling or working state. There is no BSOD, it just reboots. In eventviewer I only get the message that Windows has shut down unexpectedly.
What I've done so far to try to solve all this: I removed/disabled all programs/services that I don't need. That helped for a while and greatly improved boot time. I made sure my drivers are all up to date and working fine (Windows found a newer version of my graphics card driver and installed it). This helped for some days.
Then I went into the BIOS. Well, in fact it is UEFI to check settings. I changed some settings, like chassis fan 2 (it showed red, when in fact nothing was wrong: rpm's, etc). I made sure that all other settings were correct.
So far, this has worked correctly for over two weeks now. But what I want is a real solution and no workarounds.
My PC specs:
Motherboard: Asus P8Z68 deluxe
Processor: Intel I5 Quadcore at 3.1 Ghz.
Memory (RAM): 16 GB Corsair (4x4 GB modules at a safe setting of 1333 Mhz (standard setting))
Western Digital 2 TB harddisk
Graphics: nVidia 550 GTX (1 GB video memory)
This PC has always worked flawlessly, until I decided to reinstall in October this year.
All updates for Windows 7 (x64) are installed.
Although things seem fine now, I'm still not sure.
Maybe any advice?
