Solve : pc randomly turns off?

1.	Solve : pc randomly turns off?
Answer» When it "turns off" the monitor goes black and my speaker loudly echoes whatever the last MOMENT of sound was it got from the pc. All of my fans and leds still appear to be on as if my computer just stopped outputting. MEMTEST86 should be run on this system... RAM ( Memory ) Issues can cause this audio noise loop and black screen. Additionally a power supply that is not up to par can dip ( low voltage ) and cause a drop out of the system but it to stay running and black screen. What make/model computer or specs?i added my specs to my profile i believe please run memtest86 for a few passes to make sure RAM healthy. then crystaldiskinfo to make sure hard drive healthy in case issue with virtual memory crash. How are your temps & fan SPEEDS? Any error messages or it just drops out/off? Also do make sure that you have all the Windows latest updates and drivers installed. windows is up to date. i have two 140 mm fans PULLING air in the front. 2 120 mm in a push/pull config pulling air in the rear through my cpu's radiator. and 3 140 mm exhaust fans blowing out the top. i never get an error message. when i pull google chrome up after it crashes it asks to restore my pages. i just did memtest86 and got no errors it passed perfectly. took 55 min. going to download crystaldiskinfo next and try that. just downloaded the program it says both my ssd and hdd are in good conditionsooooo no help then?How much stuff do you have at hand? Do you have another motherboard that will accept all lour things? Try a test of everything in the spare motherboard.* FYI Memtest86 does not test all memory. - Unless you use the 64 bit version. Quote 64bit - From version 5, MemTest86 is native 64bit code http://www.memtest86.com/ no i dont have a second motherboard unfortunately. this is my first custom pc build and i love it its my new hobby but i have absolutely no spare parts. idk if this helps but it also turns on by itself completely randomly. like i got home today and it was on...waiting for me...which is cool but not something i want obviously. not sure if the problems are related though Booting itself could be WoL ENABLED in BIOS, look in there and see if its enabled or disabled and signal is triggering it to boot on the LAN or power supply ripple or motherboard capacitor dying and causing ripple causing it to trigger soft power boot. Its probably Wake on LAN that is causing it to boot. I have had my one computer with WoL enabled turn itself on as for somehow the local network is triggering it. Disabling this in BIOS fixed my issue with WoL booting the system when shut off.awesome ill try that. anything for why its turning off? open up "event viewer" i can only find it on Win 7 if i do the file search for "event viewer" in the START menu but it should have logs for everything that happened on ur PC perfect for figuring out why crashes are happening u may have to scroll quite a bit to find the date and time of the crash but it should be in there. if they are random crashes that happen in a number of different programs or regardless of what you are doing on there, it should be in the "System" logs in the Windows log drop file

Try a test of everything in the spare motherboard.

no i dont have a second motherboard unfortunately. this is my first custom pc build and i love it its my new hobby but i have absolutely no spare parts. idk if this helps but it also turns on by itself completely randomly. like i got home today and it was on...waiting for me...which is cool but not something i want obviously. not sure if the problems are related though
Booting itself could be WoL ENABLED in BIOS, look in there and see if its enabled or disabled and signal is triggering it to boot on the LAN or power supply ripple or motherboard capacitor dying and causing ripple causing it to trigger soft power boot.

open up "event viewer" i can only find it on Win 7 if i do the file search for "event viewer" in the START menu but it should have logs for everything that happened on ur PC perfect for figuring out why crashes are happening u may have to scroll quite a bit to find the date and time of the crash but it should be in there. if they are random crashes that happen in a number of different programs or regardless of what you are doing on there, it should be in the "System" logs in the Windows log drop file
