PC randomly shuts off and randomly boots up after (sometimes).
Hi there,
I am here in bad need of help to figure out what is going on with my pc of late.
A quick run down of the problem. When the PC is on it will depending on how long its been on will randomy just shut off. When it shuts off, it "sometimes" reboots but most often it "tries" to reboot but fails and then stays off. After this failed try to reboot if I press the power button on the case and mobo, nothing.
Now if I turn OFF the PSU leave it for a few minutes and come back turn the PSU switch on and press the power button the system comes to life for a second or two then dies and will no respond to the power buttons until I turn off the PSU again.
I have gotten it up and running from this state by leaving it off and unplugged for a couple of hours. When I say the PC comes to life for a second or two, I mean the case fans. If I get it booted up the BIOS is reset to default for some reason. Also if it makes it to windows, the notification area icons also gets reset... very very odd.
I have a short video of the problem, sorry for the darkness, I finally decided to video it and it was 11pm.
My first thought... PSU dying or Mobo. I dont have extra's so I cant test them.
Forgot to mention, ive checked for heat problems but none of my temps are high, they are all normal and its a Antec 1200 with tons of air movement. I keep my PC clean but this problem I just cant solve.
Event Viewer shows nothing expect for unexpected shutdown. My event viewer is clean from any errors also. I do not get any BSOD and this is on a fresh Win7 install from late Jan. Its been doing this thing now for a couple of months. I am 99.9% positive it is not a software problem.
