Hey guys.
A little over a week ago, my computer started freezing when playing games. Anything from hearthstone to more 3D heavy games, results in my PC locking up, forcing me to do a hard reset.
No BSOD, just the sound going crazy and eventually silent, as long with the picture freezing up.

It's not very consistent, sometimes it happens within a minute, sometimes i can play for hours.
I've tried pretty much all the solutions i could find, relating to the "Kernel Power 41 (63)" entry in my windows log. But as far as i know, it pretty much just says, that i had to do a hard reset, so it's a bit of a wild goose chase.

I've updated all my drivers.
Tried reverting back to some older NVIDIA drivers using clean install.
Installed MSI Afterburner to monitor temps.
Disabled extra HD Audio devices.
Unplugged wireless gamepad dongle (weird I know, but it helped for some :D)

I'm running Win7 64-Bit
i5-2500K 3.30Ghz
8GB Ram
Geforce GTX 560Ti
OS is installed on Samsung SSD 850 Pro 256GB
Motherboard is a MSI P67A-G45 B3, Socket-1155.

Help me Obi-Wan Kenobi's, you're my only hope! :D

EDIT* To add specs and stuff.

I'm certain it's your PSU.
Probably dying due to age and use.
600W is sufficient. Purchase another CX 600.

You may prolong the life of a PSU with proper ventilation and perhaps a surge protector.
