Technical difficulties!

My PC has been having some issues and we've been trying to diagnose them, so things might be a little bit slower for me.  

When I'd be playing games, it'd just turn itself off after a while of playing. Things don't seem to be overheating, but we think it might be the PSU giving in.  

It gave me some trouble in the past and still is a little iffy at times with powering on/off correctly, so we're going to try and replace it and hopefully that solves it.  

Apologies if I'm slower with works! But it's been very stressful since I'm not the most technical minded with this kind of thing.

I'm also scared I'll break things and lose my PC, since I don't have a lot of money right now to replace everything.

But I'm doing my best to keep positive and hopefully we fix it!
