pc keeps on shutting down

[darkangelire66]

I recently bought a r9 280x & after I installed it I got a warning 3.3v voltage 3.744. soon after that it started shutting down. the power supply is 750 watts so lack of power shouldn't be an issue. any ideas as to what's going on ?

have you plugged in both the connectors?

It's not shutting down from lack of power, it is shutting down from too much power on the 3.3v rail...

If you have another power supply available switch it out and see if it still gives the error, if not you found the problem, if the error persists it is unlikely but it could be the motherboard, my bet is the psu.

Maybe find a friend who is wiling to help you out, or go to a pc repair shop and see if they will help you out.

reinstall your drivers for the gpu and mobo. I had this same problem but mine turned out to be a power supply issue.
