New Build Constantly Restarting

[BabyPCMR]

Hello all,

 

So i just put together a new build, it's just an office machine with no GPU. After I put it all together it was doing this strange thing where every time it got into Windows the PC would restart. Sometimes it was a couple seconds into logging in and sometimes it would not let me log in at all before restarting. Here's the kicker though, if I entered the BIOS and did not go into Windows then the PC would be completely fine and not restart no matter how long I stayed on the BIOS. As soon as I leave the BIOS it would try to load windows and restart. I thought it might have been a software thing, so I reinstalled Windows, but even trying to get into the USB drive that I had to install Windows with would cause a restart. This leads me to thinking it must be hardware. The only thing I did was mess around with the power supply, draining the power from it, flicking it off and on, and the machine would finally go to Windows. I am not sure that completely fixed everything however because it did do a sudden restart once more after that but has not done it since for some reason. Another issue that may be related is that occasionally the monitor would just turn black while using the PC, sometimes I have to restart the PC to get the image back or just move the mouse a little and the image will come back. It's weird because it wasn't like I hadn't touched the mouse in a few minutes and the screen turned black, It was literally happening within a few seconds of last using the mouse. I am not sure what the problem is, a few areas that I think might be the issue: The case I'm using is the Fractal Era ITX, and it has one of those power cables extenders that you have to use because the power supply is in the front of the case, the cable might be bad but i'm not certain. Another culprit could obviously be the power supply, I am using the Corsair CX450 at the moment. Perhaps it's the RAM? I am really not sure. One side note, the power supply fan does not seem to get a ton of airflow to it in its current orientation, might this be an issue causing the problem? It's not completely blocked off or anything, and the machine does not draw a lot of power to begin with. 

 

Thanks to anyone who took the time to read this, and hopefully has any insight as to what the issue might be, I appreciate it very much!

Thanks for the link jonny!

It mentions on there that the system would get a blue screen of death (BSOD) when an error occurs and then restart, but I never got that blue screen however I did notice that windows was "Trying to repair" itself before it then abruptly restarted over and over again. Not sure if they are related. 

I mentioned that this restarting problem is not happening anymore, or at least has not happened since fiddling with the PSU but I am having a few other issues that I mentioned in my above post. Do you have any guess as to what the problems might be connected to? Could the PSU be faulty or was it some other component that was responsible?

I just don't have enough knowledge about this to come to an exact conclusion.

By default, "automatically restart" is checked.  So you would not get a BSOD.

 

If you uncheck the "automatically restart" and the problem is not PSU related, then you get a BSOD instead of a restart.
