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.
