Computer Randomly Restarts

[Icemanskis]

I built a computer with a water cooling system about 2.5 years ago. It randomly restarts or shuts off with no warning. Sometimes it goes months without doing this and then becomes a problem for a while again. There is no rhyme or reason to why it does this.

There is no overheating issue and he PSU is working fine. If I jostle the case or touch the graphics card with my hand it usually will turn back on. It feels like some type of a hardware issue. Do i simply change out part by part (i.e., motherboard, graphics card, RAM) to see if any of that will correct the issue?

Or any ideas on how to figure out what the problem is?

Thank you

This seems like it may be a motherboard issue. perhaps your motherboard is shorting on something. or it could just be a dying Motherboard.
