Hello,

I recently had some help upgrading some parts of my computer (motherboard, CPU, and CPU Cooler). The computer was running fine for the most part, but now I am getting Kernel Power Error 41 63 in the Events Viewer after the computer randomly restarts. I have tried multiple things that I have read on the internet so far, such as disabling audio drivers and restoring the BIOS to default settings (although I never overclocked anything so i dont see how that would affect anything).

One thing that I am noticing is that before my computer restarts, the one video card reaches temps of about 90 degrees, which I feel is a little high. Any insight or things that I can try would be appreciated.

My current build looks like this:

Well, I will be the first to admit that I am not the most computer-saavy person. I believe that it is hooked up correctly. I have an 8-pin connector plugged into the motherboard, but out of the 8 pin connector there is a 4 pin connector that is coming back out. Is that the one that should be there?
