Computer randomly restarts without warning plz help

[tristan65487]

I don't know what is causing it. The computer will randomly even while no one is in the room, turn off completely / or / Restart instantly. There is no warning or notification and there is no pattern to the restarts. The computer goes directly off, no screen or anything. From gaming to black screen and the tower goes off as well.

Here is a pastbin of my MSinfo, if any other info is needed please just let me know how and where to get it and I'll post it as soon as possible.

No one responded, but it was the temperature. For now I have a box fan pointed at my tower to control the heat because I don't have the money to replace the heatsink...

may not be just the heatsink.
also replace the thermal paste and consider getting better, or adding more, chassis fans.
don't forget there is a fan in the PSU, it may not be working.
same goes for a graphics card if you have one and it uses active cooling.

@ardogan,

his reply #1 pointed at a temp issue.  good 'ol external fan solution seems to have worked.

was your issue with the HD temp or a failing HD?
