your power supply is dying
they are about anywhere from $50 to $100 avg

I think I found the problem. You have your monitor set to some microscopic resolution.

EventViewer told you the problem: Kernal Power.

Plug that into Google, and we find a solution very quickly (top link actually):

If event 41 is logged because power to the computer was interrupted, consider obtaining an uninterruptible power supply (UPS) such as a battery backup power supply. An underpowered or failing power supply may cause this behavior. For example, if you added RAM or additional devices or hard disks when this problem began, the power supply may cause the problem.

TL;DR: Get a new power supply.

Yeah this happened to me, the power went out during a thunderstorm. Then my computer would keep restarting, it was the power supply that was f***ed.

There are many things that could cause this issue..

I would first start by checking the fans that are on your CPU and your GPU...

Sounds like a similar problem I had and it turned out to be a dead graphics card fan....... It could just be an overheat issue....

It looks as a hardware issue, the event viewer can't help you. Clean your pc carefully with a can of compressed air for electronics, use a software to monitor the temperatures, the voltages of your motherboard and the fans RPM. Does it restart when CPU is loaded or even when it's in idle state? Have you a quality power supply or a 10$ unbranded one?

It's most certainly power supply related. Either the box itself is damaged, or the lines/connectors in and out of the motherboard. If your area is prone to surges, I'd check to make sure your surge protector isn't bricked as well.

I had a similar if not even the same issue - PC would randomly restart, especially when playing games - could do 2-3 hours at first, after a while it wouldn't last even 5 min. :p
Bought a new PSU and it works nicely now. :)
