Question Pc randomly halting, freezing and restarting

[gamesx3]

While I'm doing anything either browsing or just playing games, my pc sometimes just freezes for a couple of seconds and then restarts randomly. A few months ago I thought it could be the PSU so I changed it but the problem kept going.
Any suggestions ?

Could be a variety of reasons. Keep an eye on your system temps and see if they are within normal range. Another thing worth trying is see whether your ram may be developing some issues-try running memtest for a few full cycles and see if it comes up with anything worrisome.

I ran memtest a couple of times and found no erros I'll keep an eye on my temps then to see if I find something unusual. Thanks for the advice.
