I built a PC over the summer and recently it started to randomly shut down. Sometimes multiple times a day, and other times it is fine. I do not get any error messages, and it seems to turn it back on i have to tilt it forward. I am going to open it and see if maybe there is a loose wire, but other than that i do not even know what i should be looking for.

Hi

Have you checked the obvious - i.e the cpu temperatures?

Yes I have using Everest, which now doesn't want to work but i believe the CPU was around 40º. Sorry, but I do not know what the temperature should be at.
Just Checked using HWMonitor they were 32-36

Your cpu temps seem fine so doesn't look like that's the cause.

Random shut downs with no warnings can be very hard to diagnose. If you haven't already done so, then check all the connections inside the computer. You've got a modular PSU so remember to check the connections at the PSU as well as at the motherboard etc.

I would also check Event Viewer just to make sure that nothing has been logged in there at the moment, or just prior to the system shutting down. Obviously you'll need to make a note of the exact time when the next shut down occurs so you know what to look for in the logs

It may even be worth trying a different power outlet if possible
