Hi guys,

I've got this problem for over 3 months now which I thought was minor at first but now I'm afraid it's going to break some of my other hardware pieces.. My computer goes to sleep mode when it stays idle for a little while like most others do I suppose; problem is, at some point during that process it shuts down and tries to restart on its own, but it does it over and over and over again (You can hear the fans opening up as when you open your computer, then everything shuts down, and it restarts the process again..) until I just close down the power, wait a few seconds then restart power and reopen the computer normally.. It'll give me the little "Windows was closed improperly last time" or something then I just choose restart Windows Normally and it'll come back to the windows screen as if my computer went into sleep mode (User: xxx Locked in windows 7, then I just log in normally).. I suspect it's a hardware problem and one component is failing but I have no idea what it could be and I don't want to start replacing pieces one by one randomly..

More recently, the computer started giving me blue screens of death (yes on Windows 7, I thought those were gone!) randomly (maybe when it's thinking a little too hard?) but that doesn't trigger the repeated sequence mentioned above, it just crashes and restart on its own.. The repeated restarts only are triggered by the sleep mode process if I'm not mistaken..

I'm afraid it's a problem with the power supply and that it might cost problems with the other components eventually, on top of being extremely annoying when I fall asleep with the computer on still and then I get awaken in the middle of the night by the noise of the stupid fan restarting over and over again..

Can you guys help me? Any idea what the problem could be?

Thank you so much in advance.

Simple solution might be to turn it off when not in use.

Put it all on a power strip and turn all the ac adapters off too.Might cost $8 to $30 for the power strip.

Otherwise you would need to look at pc health status in bios for failing voltages. Might be an issue with acpi either in bios or os or both. Might be an odd but known issue with power supplies not reacting to the motherboard. MB and PS makers tend to blame each other. PS may not be getting OK from MB and starting to shut back down.

The solution may require swapping with known good components. Not easy for a home user.

Are you monitoring the system temperatures?

As jefro stated check the settings in PC Health in the BIOS. Having the shutdown threshold set too low will cause that.
Change the setting so that Windows will not automatically restart on system failure.

Read the BSODs to help determine what your problem is.

Try adjusting the power settings to never shut off the hard drive and to never hibernate or sleep.

I checked it, they were all disabled, so no shutdowns due to temperature nor part failures were made.. as far as temperature goes.. I'm using Everest Ultimate, thats the temperatures I have at the moment..
