Hey guys,

In the past week or so my PC has been misbehaving quite a bit :(

It’s been restarting pretty much when it feels like it? Once or twice every few days or so?

I’ve narrowed it down to my (New at Xmas) PSU, it’s the only thing it can be right? The other thing I thought it might be was my RAM, but I ran memtest+ the other night for 12 hours and it was fine, no errors?

So, back to my PSU? Here’s my latest readings, and by watching them it would seem that the +5v is very erratic – it frequently drops below 2.12v in just seconds?

Is that the cause of my problem? Nothing else has changed in my system, see spec bellow.

Cheers,

SW.
 
Wow, thanks for the responce guys :D

I've got a multimeter so I'll probably give that a try first - but looking at the 5v rail now it's, 2.85v, and that can't be right?

I'll also have a look in the BIOS because that can display my rails too can't it?

It’s a Enermax, so I should be okay for a RMA? Anyone had any experience with their procedures? Do I get in touch with them direct or get in contact with my supplier :rolleyes:

Cheers,

Hi guys,

Just an update, my machines been on and fine all day? the 5v rail has been up and down the whole time though? But then I just went to play CoD and I got a restart :(

I'm going to start an RMA off tomorrow with the supplier, it's annoying, I bought the Enermax on the strength that they never go wrong...

It's lasted 3 months I suppose :rolleyes:

I got as far as taking the side of the case off, then I realised I didn't actually know what to do :eek:

I haven't used one of these things since high school...

Any chance of some brief instructions Phil99?

Cheers,

SW.
 
Thanks for the instructions ;)

I took two readings from the molex (750v~ and 200v~) 011 and 10.4 - does that make any sense to anyone or am I doing it wrong :(

Cheers,

SW.
 
I took that reading from the molex pins like you said? I had another restart last night so I'm concluding that the PSU is actually faulty... :(

Thanks for your help ;)
