Testing PSU?

I've been having problems recently with my PC.

When I used to turn it on, the fans would come on full for a second or two and then they'd die down and it'd boot up (all normal), but recently they've been staying on full speed and I get absolutely no output to the screen, the monitor thinks the PC is turned off. I have to totally disconnect the power for a few minutes and then try again, and usually it boots up fine after that.

I'm starting to think it's probably a power supply problem for some reason, but it's extremely hard to diagnose because it's so random. Things can be fine for a month then it'll happen again.

What's the easiest/best way to test the power supply properly? Without having to borrow someone else's to see if that fixes it. Saw a tester thing online but wasn't sure how well they'd work for this problem?

Thanks

What's your setup? What I'd do is make my conf the simplest I can : 1 RAM, no graphics card if you have an integrated one, then reset your BIOS and try to boot that way.

If there's still no boot then you'll have to borrow a test-PSU...

Hope that helps...
 
Well I've tried that before, but as I say (not sure if you posted before I edited), I can't really diagnose it with the usual methods because at the moment it's working perfectly with everything in. I can turn it on and off now and it'll work fine, but in a few days it'll probably mess up again.

I was hoping for a way that I could actually plug the power supply into something for a while and check it's working as it should.
 
Ahhh alright! Nah I didn't see your edit. Right... well I'm not an expert (and by this I mean I've never had to do this) but I'm generally knowledgeable enough. You might wanna check OCCT or some equivalent that might give you voltages values and look if they are coherent...
 
OCUK used to sell a psu tester you just plugged your psu onto it and it showed voltages for all your rails :(
can`t see them on the site any more though

This is what it comes up with... doesn't mean a massive amount to me but hopefully someone else will know if there's anything wrong with that.

Hmm, that sounds like the kinda thing I need. I've seen the multimeter things but they look a bit awkward to use!
