system restarts randomly

[AngryCherry]

I have been having random restarts while playing games recently and I was wondering if someone could help?
I have looked at the event logs and in system it says kernel-power is critical and I have a warning for Kernel-PnP it talks about driver/WudfRd failed to load for the device SWD/SensorsAndLocationEnum/LPSensorSWDevice

Someone help?

Thanks in advance

Please tell us your complete system specifications, including power supply, cpu, gpu, motherboard, etc.

I have a rosewill 630W PSU
CPU: AMD A6-3620
GPU: EVGA GTX 660 SuperClocked 2GB
Motherboard: Acer Aspire m3470g (Pre-Built but with an upgraded psu and gpu.)
RAM: 4GB DDR3
HDD: WD Caviar Green 1TB

That should be it.

Looks like some plug n play device may be malfunctioning or possibly your power supply is having a hard time giving juice, although it seems highly unlikely with your PSU.

I think I missed your OS - what are you using?

Try updating all of your drivers.

I have windows 8.1 64-Bit and could you help me find drivers my nvidia ones are up to date and the amd processor drivers I can't find.
Any other drivers would be great as well.

If you go here you should be able to find your drivers:

Put in your model/ or serial number.

I just did a quick check and I found this: "Need to know the hardware on your system to choose the right drivers?" This download should allow you to see all of the hardware you have - you may need to download the drivers individually for each component.

Did you install windows 8.1 over your current computer, or did it already come with windows 8?
