Help needed: PC shuts down, is it the power supply?

#1lolman7712Posted 6/7/2014 7:42:16 PM(edited)
Okay, so here's the deal. I'm busy doing some lazy internet browsing on my PC like it's nothing. Then it shuts down randomly.

"Oh boy," I think, "this better not be the cpu again." I boot to the BIOS to see nothing out of the ordinary temperature-wise, so I wonder what it could be. I go back to just sit on the desktop, and it shuts off again.

The thing is in a state where it should be on, but it's like it gets cut off from power so it shuts down until power comes back, if that paints the right picture. I'm worried here, guys. I put together the thing myself and it's been working the past 2 months all right, so I wonder what the cause of it is. Nothing seems out of the ordinary when I checked inside. Am I missing anything? The thing is just sitting there, off. I'm waiting to understand more about this.

Please help me, PC board. What should I do? I'll post specs if I need to. Thanks in advance.

The PSU is a good place to start, but it's always hard to tell in these situations. If you get a different (good quality) PSU and the problem goes away, that's basically the only way you'll know...
What PSU do you have now (brand and specific model, not just wattage) ?

Yeah the PSU would be one of the first places I'd look. Check your system logs too and see if the errors have anything useful

Some roads you shouldn't go down because maps used to say there'd be dragons there. Now they don't, but that don't mean the dragons aren't there.

It's an Antec VP-450. How well is it? I'm hoping good quality power supplies aren't too expensive.

In my experience the motherboard is the most fragile part of a PC.

Edit: Correction HDD is the most fragile then motherboard.

It's an OK unit, but that doesn't mean it couldn't be crapping out on you.

Not really... I'm not 100% sure what you meant, there are a great number of factors at play here.
