Hello all,

I would like to ask you for help.

I have recently bought a case for my PC and I managed to put everything together nicely and the computer was running without any problems.

Then, when I started a game, the 3.3V was at 3.8 voltage and my VDDA was at 2.8, giving me warning about high voltage. After 2-3 sec after giving me the warning, the Interned fails and I have to restart the system. After this happened, I tried to do the same, so I started the game again and the same warning came up again. The internet connection was lost again and it never came back (meaning: I still have no internet even after restarting my PC).

I don't know if this is important, but after turning on my computer for the first time after putting it together, my AI Suite II language changed to Chinese and Windows date was completely messed up (it was set to 2009 and completely wrong time zone).

My specs are:
900W Power Supply
CrossAir H80I Cooler
AMD FX-8150 black edition CPU
motherboard Asus m5a99x evo R2.0
Gigabyte HD7950
2 x 4GB RAM
3 x chasis fans
TP-Link TL-WN881ND 300Mbps Wireless N PCI-E Adapter

Thanks for the help guys!

The VDDA thing is weird, I don't know what's up with that. Someone else might know though.

I believe the norm for PSUs is that a divergence of 5% from the given voltage is acceptable. For 3.3v that would mean an actual voltage that's between 3.135 and 3.465 at all times. That kind of unstable VCore is worrying too, it's never completely stable but a 0.7v difference is really bad.
Software monitoring can be off a bit though. If you can't check the PSU with a voltmeter/multimeter/whatever yourself then your best bet would be to take the PSU to a computer repair shop, they can check if everything is working correctly for you.

I have a Pentium P4 MODEL: PC-950AUBA-B

And the 3.3V was actually at 2.8v not 3.8v

And yes it is the same person replying i just asked someone else yesterday to make the post because i didin't had internet connection

Is your system overclocked? If so, put everything back to stock and see if that helps.

Did you only change the case or did you also change other parts? It sounds like a failing PSU but the timing is a little weird if you didn't change any other parts.

Before we jump to conclusions though you'll want to make sure all the cables are properly connected, redo it if you have to and if you have any replacement cables this would be the time to try them out.
Also if you have a voltmeter use that to check the actual voltage output of your PSU, if you haven't already.

My sistem is not overclocked. I changed the cade and the cooler.

I also noticed that after removing the wireless adapter the +VDDA no longer gives any problems the only problem now is the +3.3V which goes to 2.8V when I run a few programs or even a game and the Vcore it is jumping from 0.8V to 1.5V so it is not stable but i dont know if it's normal or not.

I already checked all the cables and the only thing that comes to my mind is the fact that i didn't had the screws for the CPU Cooler bracket so i used a different kind of scrwes but i checked and the bracket is well fixed to the motherboard.

Also when I notice that the voltage is getting to low i stop doing what I was doing and eventually it goes to normal voltage of 3.2~3.3V
