3.3V jumping very HIGH

[trax7]

So recently my computer started to turn off by itself. At first, I ignored it but then it became more frequent started turning off earlier so I became worried. Now most of the time it can stay on for about a minute and then it turns off by itself. Then I can't turn it on without turning off the PSU itself from the little button in the back. I checked in the BIOS and with a voltmeter and it showed that the 3.3V was way WAY high and rising until 3.8V - then it turns off. I have a Corsair TX650W PSU and my MB is ASUS M4A785TD-V EVO.

Check what voltages are showing in the bios please.

I have checked - the 5V, 12V and VCORE are all stable and ok but the 3.3V gradually rises from 3.4 to 3.8V from the time I start the computer. Here's a pic from just before it turned off.

Yeah, it figures... But I wondered if there is a way to fix it. It's warranty period has passed anyway so I've opened it. I can take pictures of it open if it's of any help.

No, it is not worth going through trying to repair... Just purchase a new quality Corsair supply or the like and you won't have to worry about it any longer. I have a 650 Watt Corsair powering my rig going on for almost six years now, still going strong

Well, mine is 5yrs old. Anyway, I think I'll have a go at it. I just thought I'd ask if anyone already had a solution. Thanks guys
