In the past few months, I've had sporadic issues with booting up my PC, like once every couple of months. Clearing the CMOS battery always did the trick.

However this morning when my PC didn't boot, clearing the CMOS was not enough. I thought it was probably time to replace it but I heard an electricity-type noise when trying to remove it, so decided to try booting again. It worked.


A few hours later, my PC hard crashed (no freezes, nothing, it just turned off) when opening a couple of "heavy" tabs on chrome. I had to give it a slight nudge again for it to restart. A bit of googling tells me the CMOS battery shouldn't be responsible for shutdowns and it's probably a PSU issue. I guess I just want to make sure I'm not missing anything obvious before I go and buy a new 550W+ one.

I would replace it or see if you can borrow another persons to make sure its the issue and not some other component. A bad PSU can ruin your stuff so I would be careful with this one. (Me personally I would just get a new one)

I am a human that makes mistakes! If I'm wrong please correct me and tell me where I made the mistake. I try my best to be helpful.

How old is the PSU? if more than 3 years, it's okay to buy a new one, even if it's not the problem.

If less, you can send it back for replacement.

This time you buy a better quality that that one.

with things like these you don't play.

I had an old pc crash and do all sorts of weird things because of a blown up psu.

You should really look into getting a NEW decent PSU.

PSU celebrated its third birthday a few months ago. Don't really have anyone I can borrow a PSU from, so it looks like it's time for me to get a new one and see how it goes. Thank you very much for the replies, guys !
